81-504: Curtiss-Wright purchased a license for the Sapphire in 1950, with plans to have the production lines running in 1951. However a series of delays due to design changes by Curtiss-Wright, such as substituting the Sapphire's machined midsection solid forged diffuser frame with a fabricated one of welded nodular iron, led to its service introduction slipping two years. The fabricated assembly, a more practicable production job with about one fifth

162-525: A Boeing XB-47D test bed from 26 August 1955. By this time however, the market for the engine had vanished. Related development Comparable engines Related lists Curtiss-Wright The Curtiss-Wright Corporation is a manufacturer and services provider headquartered in Davidson, North Carolina , with factories and operations in and outside the United States. Created in 1929 from

243-704: A 768,000 sq ft (71,300 m) portion of a purpose built plant in Willow Springs, Illinois . A 6,500–10,380 shp (4,850–7,740 kW) turboprop version of the J65 (Sapphire) was developed by Curtiss-Wright as the Wright T49 , and a commercial derivative, the Wright TP51A2 was also designed. The T49 first ran in December 1952 at 8,000 shp (6,000 kW), followed by flight testing in

324-523: A cost of $ 3 million. These simulators were unlike earlier ones produced in the late 1940s for airliners but now included visuals, sound, and movement. They were the first of today's modern flight simulators for commercial aircraft. In 1956, financially strapped automaker Studebaker-Packard Corporation entered into a management agreement with Curtiss-Wright to allow the nation's fifth-largest automobile manufacturer to avoid insolvency. The relationship lasted until 1959 at which time Curtiss-Wright withdrew from

405-481: A density 0.5539 times that of air (0.678 kg per standard cubic meter). In the early 1800s, natural gas became known as "natural" to distinguish it from the dominant gas fuel at the time, coal gas . Unlike coal gas, which is manufactured by heating coal, natural gas can be extracted from the ground in its native gaseous form. When the use of natural gas overtook the use of coal gas in English speaking countries in

486-594: A few exceptions. Throughout the 1930s, Curtiss-Wright designed and built aircraft for military, commercial, and private markets but it was the Wright engine division and the longstanding relationship with the U.S. military that helped the company through the difficult years of the Great Depression . Guy Vaughan was appointed president in 1935. In 1937, the company developed the P-36 fighter aircraft, resulting in

567-421: A major source of natural gas in the United States and Canada. Because of increased shale gas production the United States was in 2014 the number one natural gas producer in the world. The production of shale gas in the United States has been described as a "shale gas revolution" and as "one of the landmark events in the 21st century." Following the increased production in the United States, shale gas exploration

648-533: A move aimed at expanding its presence in the military aircraft emergency arresting systems sector. SAA, a subsidiary of Safran Aerosystems, specializes in designing and manufacturing aircraft emergency arresting systems and will operate within Curtiss-Wright's Naval & Power segment post-acquisition. The completion of the acquisition, valued at $ 240 million, is contingent on regulatory approval and other closing conditions, with expectations for finalization in

729-564: A supplier of specialized data communications products for real-time systems, primarily for the aerospace and defense, industrial automation and medical image markets. The acquisition also reintroduced Curtiss-Wright to Dayton, Ohio. In 2010, Curtiss-Wright acquired Hybricon Corporation for $ 19 million in cash. Hybricon is a supplier of electronic packaging for the aerospace, defense, and commercial markets, and provides electronic subsystem integration. In 2011, Curtiss-Wright acquired Ireland-based Acra Control for $ 61 million in cash. Acra Control

810-542: A synthetic crude that can be further refined into finished products, while MTG can produce synthetic gasoline from natural gas. STG+ can produce drop-in gasoline, diesel, jet fuel and aromatic chemicals directly from natural gas via a single-loop process. In 2011, Royal Dutch Shell's 140,000 barrels (22,000 m ) per day F–T plant went into operation in Qatar . Natural gas can be "associated" (found in oil fields ), or "non-associated" (isolated in natural gas fields ), and

891-493: Is a flammable gaseous fuel made by the destructive distillation of coal . It contains a variety of calorific gases including hydrogen , carbon monoxide , methane , and other volatile hydrocarbons , together with small quantities of non-calorific gases such as carbon dioxide and nitrogen , and was used in a similar way to natural gas. This is a historical technology and is not usually economically competitive with other sources of fuel gas today. Most town "gashouses" located in

972-421: Is a naturally occurring mixture of gaseous hydrocarbons consisting primarily of methane (95%) in addition to various smaller amounts of other higher alkanes . Traces of carbon dioxide , nitrogen , hydrogen sulfide , and helium are also usually present. Methane is colorless and odorless, and the second largest greenhouse gas contributor to global climate change after carbon dioxide. Because natural gas

1053-458: Is a schematic block flow diagram of a typical natural gas processing plant. It shows the various unit processes used to convert raw natural gas into sales gas pipelined to the end user markets. The block flow diagram also shows how processing of the raw natural gas yields byproduct sulfur, byproduct ethane, and natural gas liquids (NGL) propane, butanes and natural gasoline (denoted as pentanes +). As of mid-2020, natural gas production in

1134-540: Is a supplier of data acquisition systems and networks, data recorders, and telemetry ground stations for both defense and commercial aerospace markets. At the beginning of 2013, Curtiss-Wright acquired Exlar Corporation for $ 85 million in cash. Exlar, a private company, is a designer and manufacturer of highly engineered electric actuators used in motion control solutions in industrial and military markets. The acquired business will operate within Curtiss-Wright's Motion Control segment. In October 2013, Curtiss-Wright completed

1215-399: Is also found in coal beds (as coalbed methane ). It sometimes contains a significant amount of ethane , propane , butane , and pentane —heavier hydrocarbons removed for commercial use prior to the methane being sold as a consumer fuel or chemical plant feedstock. Non-hydrocarbons such as carbon dioxide , nitrogen , helium (rarely), and hydrogen sulfide must also be removed before

1296-454: Is anticipated to yield a 100% free cash flow conversion rate, underscoring the robust liquidity position. This strengthened financial position can be leveraged for profitable and revenue-generating strategies. As well as manufacturing engines, a range of electrically actuated constant speed three- and four-bladed propellers were manufactured under the name Curtiss Electric . Albert Kahn Associates designed several industrial buildings for

1377-628: Is beginning in countries such as Poland, China, and South Africa. Chinese geologists have identified the Sichuan Basin as a promising target for shale gas drilling, because of the similarity of shales to those that have proven productive in the United States. Production from the Wei-201 well is between 10,000 and 20,000 m per day. In late 2020, China National Petroleum Corporation claimed daily production of 20 million cubic meters of gas from its Changning-Weiyuan demonstration zone. Town gas

1458-537: Is estimated to have 51,000 cubic kilometers (12,000 cu mi) of natural gas and 50 billion barrels (7.9 billion cubic meters) of natural gas condensates . Because natural gas is not a pure product, as the reservoir pressure drops when non-associated gas is extracted from a field under supercritical (pressure/temperature) conditions, the higher molecular weight components may partially condense upon isothermic depressurizing—an effect called retrograde condensation . The liquid thus formed may get trapped as

1539-694: Is heated and compressed deep underground. Methanogenic organisms produce methane from a variety of sources, principally carbon dioxide. During petroleum production, natural gas is sometimes flared rather than being collected and used. Before natural gas can be burned as a fuel or used in manufacturing processes, it almost always has to be processed to remove impurities such as water. The byproducts of this processing include ethane , propane , butanes , pentanes , and higher molecular weight hydrocarbons. Hydrogen sulfide (which may be converted into pure sulfur ), carbon dioxide , water vapor , and sometimes helium and nitrogen must also be removed. Natural gas

1620-403: Is natural gas produced from shale . Because shale's matrix permeability is too low to allow gas to flow in economical quantities, shale gas wells depend on fractures to allow the gas to flow. Early shale gas wells depended on natural fractures through which gas flowed; almost all shale gas wells today require fractures artificially created by hydraulic fracturing . Since 2000, shale gas has become

1701-408: Is odorless, odorizers such as mercaptan (which smells like rotten eggs ) are commonly added to it for safety so that leaks can be readily detected. Natural gas is a fossil fuel that is formed when layers of organic matter (primarily marine microorganisms) decompose under anaerobic conditions and are subjected to intense heat and pressure underground over millions of years. The energy that

1782-406: Is often stored underground [references about geological storage needed]inside depleted gas reservoirs from previous gas wells, salt domes , or in tanks as liquefied natural gas. The gas is injected in a time of low demand and extracted when demand picks up. Storage nearby end users helps to meet volatile demands, but such storage may not always be practicable. With 15 countries accounting for 84% of

1863-452: Is preparing to export natural gas. Floating liquefied natural gas (FLNG) is an innovative technology designed to enable the development of offshore gas resources that would otherwise remain untapped due to environmental or economic factors which currently make them impractical to develop via a land-based LNG operation. FLNG technology also provides a number of environmental and economic advantages: Many gas and oil companies are considering

1944-548: Is primarily dependent on proximity to markets (pipelines), and regulatory restrictions. Natural gas can be indirectly exported through the absorption in other physical output. The expansion of shale gas production in the US has caused prices to drop relative to other countries. This has caused a boom in energy intensive manufacturing sector exports, whereby the average dollar unit of US manufacturing exports has almost tripled its energy content between 1996 and 2012. A "master gas system"

2025-429: Is primarily used in the northern hemisphere. North America and Europe are major consumers. Often well head gases require removal of various hydrocarbon molecules contained within the gas. Some of these gases include heptane , pentane , propane and other hydrocarbons with molecular weights above methane ( CH 4 ). The natural gas transmission lines extend to the natural gas processing plant or unit which removes

2106-716: Is sometimes informally referred to simply as "gas", especially when it is being compared to other energy sources, such as oil, coal or renewables. However, it is not to be confused with gasoline , which is also shortened in colloquial usage to "gas", especially in North America. Natural gas is measured in standard cubic meters or standard cubic feet . The density compared to air ranges from 0.58 (16.8 g/mole, 0.71 kg per standard cubic meter) to as high as 0.79 (22.9 g/mole, 0.97 kg per scm), but generally less than 0.64 (18.5 g/mole, 0.78 kg per scm). For comparison, pure methane (16.0425 g/mole) has

2187-604: Is traded on a "dry gas" basis and is required to be commercially free from objectionable odours, materials, and dust or other solid or liquid matter, waxes, gums and gum forming constituents, which might damage or adversely affect operation of equipment downstream of the custody transfer point. LNG carrier ships transport liquefied natural gas (LNG) across oceans, while tank trucks can carry LNG or compressed natural gas (CNG) over shorter distances. Sea transport using CNG carrier ships that are now under development may be competitive with LNG transport in specific conditions. Gas

2268-409: Is transported at high pressure, typically above 200 bars (20,000 kPa; 2,900 psi). Compressors and decompression equipment are less capital intensive and may be economical in smaller unit sizes than liquefaction/regasification plants. Natural gas trucks and carriers may transport natural gas directly to end-users, or to distribution points such as pipelines. In the past, the natural gas which

2349-416: Is turned into liquid at a liquefaction plant, and is returned to gas form at regasification plant at the terminal . Shipborne regasification equipment is also used. LNG is the preferred form for long distance, high volume transportation of natural gas, whereas pipeline is preferred for transport for distances up to 4,000 km (2,500 mi) over land and approximately half that distance offshore. CNG

2430-862: The Martin B-57 Canberra , its original application, the J65 went on to power versions of the North American FJ Fury , Douglas A-4 Skyhawk , Republic F-84F Thunderstreak , and the two Lockheed XF-104 Starfighter prototypes. Problems Grumman had with the engine in the F11F Tiger, particularly below-spec afterburning thrust, caused them to specify the General Electric J79 for the Grumman F11F-1F Super Tiger . As part of an expansion in defense contracts, Buick also built J65s. Its version of

2511-643: The Wright J65 . It powered models of the Martin B-57 , and several U.S. fighter aircraft. Subsequent derivative engines were late and did not find substantial markets. Curtiss-Wright briefly licensed rights to the Wankel rotary engine from NSU in 1958 as a possible aircraft power plant. For this project, Curtiss-Wright relied on the design leadership of NSU-Wankel engineer Max Bentele . In 1954, United Airlines bought four Curtiss-Wright flight simulators at

2592-399: The commercial , industrial , defense , and energy markets. It makes parts for commercial and naval nuclear power systems, industrial vehicles, and oil - and gas -related machinery. Curtiss-Wright formed on July 5, 1929, the result of a merger of 12 companies associated with Curtiss Aeroplane and Motor Company of Buffalo, New York , and Wright Aeronautical of Dayton, Ohio . It

2673-424: The consolidation of Curtiss , Wright , and various supplier companies, the company was immediately the country's largest aviation firm and built more than 142,000 aircraft engines for the U.S. military during World War II . It no longer makes aircraft but does make many related components, particularly actuators , aircraft controls , valves , and it provides surface-treatment services. It supplies equipment to

2754-427: The supply chain can result in natural gas having a similar carbon footprint to other fossil fuels overall. Natural gas can be found in underground geological formations , often alongside other fossil fuels like coal and oil (petroleum). Most natural gas has been created through either biogenic or thermogenic processes. Thermogenic gas takes a much longer period of time to form and is created when organic matter

2835-548: The 19th century, natural gas was primarily obtained as a by-product of producing oil . The small, light gas carbon chains came out of solution as the extracted fluids underwent pressure reduction from the reservoir to the surface, similar to uncapping a soft drink bottle where the carbon dioxide effervesces . The gas was often viewed as a by-product, a hazard, and a disposal problem in active oil fields. The large volumes produced could not be used until relatively expensive pipeline and storage facilities were constructed to deliver

2916-406: The 20th century, it was increasingly referred to as simply "gas." In order to highlight its role in exacerbating the climate crisis , however, many organizations have criticized the continued use of the word "natural" in referring to the gas. These advocates prefer the term "fossil gas" or "methane gas" as better conveying to the public its climate threat. A 2020 study of Americans' perceptions of

Natural gas Natural gas (also called fossil gas, methane gas , or simply gas )

3078-786: The Curtiss-Wright Airplane Division, which manufactured airframes ; the Wright Aeronautical Corporation, which produced aircraft engines ; and the Curtiss-Wright Propeller Division, which manufactured propellers . After 1929, most engines produced by the new company were known as Wrights. Existing aircraft continued using the Curtiss name, while new designs used either the Curtiss or Curtiss-Wright name, depending on which location they were designed by, with

3159-432: The US had peaked three times, with current levels exceeding both previous peaks. It reached 24.1 trillion cubic feet per year in 1973, followed by a decline, and reached 24.5 trillion cubic feet in 2001. After a brief drop, withdrawals increased nearly every year since 2006 (owing to the shale gas boom ), with 2017 production at 33.4 trillion cubic feet and 2019 production at 40.7 trillion cubic feet. After

3240-427: The US, over one-third of households (>40 million homes) cook with gas. Natural gas dispensed in a residential setting can generate temperatures in excess of 1,100 °C (2,000 °F) making it a powerful domestic cooking and heating fuel. Stanford scientists estimated that gas stoves emit 0.8–1.3% of the gas they use as unburned methane and that total U.S. stove emissions are 28.1 gigagrams of methane. In much of

3321-523: The United States begins with localized use. In the seventeenth century, French missionaries witnessed the American Indians setting fire to natural gas seeps around lake Erie, and scattered observations of these seeps were made by European-descended settlers throughout the eastern seaboard through the 1700s. In 1821, William Hart dug the first commercial natural gas well in the United States at Fredonia, New York , United States, which led in 1858 to

3402-580: The acquisition of 901D Holdings, LLC (901D) for $ 132 million in cash. Designing and manufacturing electronic systems, subsystems, and shipboard enclosures, 901D is a contributor to major U.S. Navy shipbuilding programs including both nuclear and non-nuclear powered vessels. In February 2020, Curtiss-Wright Corporation (NYSE: CW) completed the acquisition of Dyna-Flo Control Valve Services Ltd. ("Dyna-Flo") for $ 81 million in cash. In January 2022, Curtiss-Wright Corporation (CW) announced an agreement to acquire assets from Safran Aerosystems Arresting Company (SAA),

3483-487: The acquisition of Keronite Group Limited, involving a cash transaction of $ 35 million. This strategic move is expected to enhance Curtiss-Wright's capabilities in Plasma Electrolytic Oxidation ("PEO") surface treatment services. Operating within Curtiss-Wright's Aerospace & Industrial segment, the acquisition is projected to have a neutral impact on the company's earnings in the initial year. It

3564-529: The acquisition of the Parvus Corporation, a business unit of Eurotech S.p.A ., for $ 38 million. Parvus is a leading designer and manufacturer of rugged small form factor computers and communications subsystems for the aerospace, defense, homeland security, and industrial markets. Curtiss-Wright acquired military communications equipment supplier Pacific Star Communications for $ 400 million, on November 2, 2020. Curtiss-Wright Corporation finalized

3645-463: The agreement. The shift of civilian aircraft to jets left the company with little of its old business, and during the 1960s it shifted to components for aircraft and other types of equipment, such as nuclear submarines , a business that continues today. In 2002, Curtiss-Wright acquired Penny & Giles , a supplier of black boxes and sensing devices (Hybrid linear, hybrid rotary and VRVT sensors). In 2003, Curtiss-Wright acquired Systran Corporation,

3726-702: The bottoms of the gashouse ovens was often used for roofing and other waterproofing purposes, and when mixed with sand and gravel was used for paving streets. Huge quantities of natural gas (primarily methane) exist in the form of clathrates under sediment on offshore continental shelves and on land in arctic regions that experience permafrost , such as those in Siberia . Hydrates require a combination of high pressure and low temperature to form. In 2013, Japan Oil, Gas and Metals National Corporation (JOGMEC) announced that they had recovered commercially relevant quantities of natural gas from methane hydrate. The image below

3807-410: The cost, was subsequently adopted for the Sapphire. Another change addressed the Sapphire's only major problem. The Sapphire was found to work well through the entire RPM range without the compressor stalling, which allowed it to dispense with inlet guide vanes or other solutions found on contemporary designs. However, in service it was found that while pressure was maintained even at low speeds and RPM,

3888-654: The decayed organisms originally obtained from the sun via photosynthesis is stored as chemical energy within the molecules of methane and other hydrocarbons. Natural gas can be burned for heating, cooking, and electricity generation . Consisting mainly of methane, natural gas is rarely used as a chemical feedstock . The extraction and consumption of natural gas is a major industry. When burned for heat or electricity , natural gas emits fewer toxic air pollutants, less carbon dioxide, and almost no particulate matter compared to other fossil and biomass fuels. However, gas venting and unintended fugitive emissions throughout

3969-446: The eastern US in the late 19th and early 20th centuries were simple by-product coke ovens that heated bituminous coal in air-tight chambers. The gas driven off from the coal was collected and distributed through networks of pipes to residences and other buildings where it was used for cooking and lighting. (Gas heating did not come into widespread use until the last half of the 20th century.) The coal tar (or asphalt ) that collected in

4050-446: The economic and environmental benefits of floating liquefied natural gas (FLNG). There are currently projects underway to construct five FLNG facilities. Petronas is close to completion on their FLNG-1 at Daewoo Shipbuilding and Marine Engineering and are underway on their FLNG-2 project at Samsung Heavy Industries . Shell Prelude is due to start production 2017. The Browse LNG project will commence FEED in 2019. Natural gas

4131-456: The engine, the J65-B-3, was approved for use by the U.S. Air Force in 1953. Components were produced by subcontractors including Oldsmobile , which built the compressor and turbine rotor assemblies; Harrison Radiator , which built the combustion chamber and tailcone; and Brown-Lipe-Chapin , which built the turbine stator blades and compressor stator assemblies. Final assembly was carried out in

4212-549: The first stages were stalling and this was causing significant vibration and fatigue issues. Wright solved this by adding inlet ramps that closed off the outer portions of the intake at low RPM. Armstrong Siddeley evaluated this for the UK Sapphires, but adopted a different solution instead. By service introduction, the Pratt & Whitney J57 was on the market and took many of the J65's potential sales. Nevertheless, along with

4293-497: The formation of the Fredonia Gas Light Company . Further such ventures followed near wells in other states, until technological innovations allowed the growth of major long distance pipelines from the 1920s onward. By 2009, 66,000 km (16,000 cu mi) (or 8%) had been used out of the total 850,000 km (200,000 cu mi) of estimated remaining recoverable reserves of natural gas. In

4374-461: The fuel found that, across political identifications, the term "methane gas" led to better estimates of its harms and risks. Natural gas can come out of the ground and cause a long-burning fire. In ancient Greece , the gas flames at Mount Chimaera contributed to the legend of the fire-breathing creature Chimera . In ancient China , gas resulting from the drilling for brines was first used by about 400 BC. The Chinese transported gas seeping from

4455-435: The gas needs to be cooled down and compressed, as the friction in the pipeline causes the gas to heat up. Many existing pipelines in the US are close to reaching their capacity, prompting some politicians representing northern states to speak of potential shortages. The large trade cost implies that natural gas markets are globally much less integrated, causing significant price differences across countries. In Western Europe ,

4536-517: The gas pipeline network is already dense. New pipelines are planned or under construction between Western Europe and the Near East or Northern Africa . Whenever gas is bought or sold at custody transfer points, rules and agreements are made regarding the gas quality. These may include the maximum allowable concentration of CO 2 , H 2 S and H 2 O . Usually sales quality gas that has been treated to remove contamination

4617-896: The gas to consumer markets. Until the early part of the 20th century, most natural gas associated with oil was either simply released or burned off at oil fields. Gas venting and production flaring are still practised in modern times, but efforts are ongoing around the world to retire them, and to replace them with other commercially viable and useful alternatives. In addition to transporting gas via pipelines for use in power generation, other end uses for natural gas include export as liquefied natural gas (LNG) or conversion of natural gas into other liquid products via gas to liquids (GTL) technologies. GTL technologies can convert natural gas into liquids products such as gasoline, diesel or jet fuel. A variety of GTL technologies have been developed, including Fischer–Tropsch (F–T), methanol to gasoline (MTG) and syngas to gasoline plus (STG+). F–T produces

4698-525: The government gave the development of the Whittle jet engine to GE , the company concentrated on reciprocating engines and propeller production for military transport and civilian airliners. With the twilight of the big piston aircraft engine, Curtiss-Wright needed a new design direction, and in 1950, Curtiss-Wright licensed the Sapphire jet engine from Armstrong Siddeley in the U.K and manufactured it as

4779-526: The ground in crude pipelines of bamboo to where it was used to boil salt water to extract the salt in the Ziliujing District of Sichuan . Natural gas was not widely used before the development of long distance pipelines in the early twentieth century. Before that, most use was near to the source of the well, and the predominant gas for fuel and lighting during the industrial revolution was manufactured coal gas. The history of natural gas in

4860-442: The higher-molecular weight hydrocarbons to produce natural gas with energy content between 35–39 megajoules per cubic metre (950–1,050 British thermal units per cubic foot). The processed natural gas may then be used for residential, commercial and industrial uses. Natural gas flowing in the distribution lines is called mid-stream natural gas and is often used to power engines which rotate compressors. These compressors are required in

4941-831: The largest peacetime aircraft order ever given by the Army Air Corps. Curtiss-Wright also sold the P-36 abroad, where they were used in the early days of World War II . During World War II , Curtiss-Wright produced 142,840 aircraft engines, 146,468 electric propellers, and 29,269 airplanes. Curtiss-Wright employed 180,000 workers, and ranked second among United States corporations in the value of wartime production contracts, behind only General Motors . Aircraft production included almost 14,000 P-40 fighters, made famous by their use by Claire Chennault 's Flying Tigers in China, over 3,000 C-46 Commando transport aircraft, and later in

Sources that consider that Russia has by far the largest proven reserves include the US Central Intelligence Agency (47,600 km ) and Energy Information Administration (47,800 km ), as well as the Organization of Petroleum Exporting Countries (48,700 km ). Contrarily, BP credits Russia with only 32,900 km , which would place it in second, slightly behind Iran (33,100 to 33,800 km , depending on

5103-489: The main plant at the Buffalo airport. During divestiture of the airframe division, the lab was given to Cornell University along with a cash gift to finish the construction of a transonic wind tunnel. Cornell Aeronautical Labs, or CAL as it was known, was eventually spun off from the university as a private company, Calspan Corporation , which has been responsible for numerous innovations in flight and safety research. After

5184-433: The natural gas can be transported. Natural gas extracted from oil wells is called casinghead gas (whether or not truly produced up the annulus and through a casinghead outlet) or associated gas. The natural gas industry is extracting an increasing quantity of gas from challenging, unconventional resource types : sour gas , tight gas , shale gas , and coalbed methane . There is some disagreement on which country has

5265-441: The pores of the gas reservoir get depleted. One method to deal with this problem is to re-inject dried gas free of condensate to maintain the underground pressure and to allow re-evaporation and extraction of condensates. More frequently, the liquid condenses at the surface, and one of the tasks of the gas plant is to collect this condensate. The resulting liquid is called natural gas liquid (NGL) and has commercial value. Shale gas

5346-737: The rapid development of jet engine technology and near-supersonic flight, this technological lag resulted in Curtiss losing a number of critical postwar military aircraft orders. The final nail in the coffin was the choice of the Northrop F-89 Scorpion over the XF-87 Blackhawk . After the F-87 was cancelled in October 1948, Curtiss-Wright shut down its entire Aeroplane Division and sold the assets to North American Aviation . Curtiss-Wright continued to occasionally venture back into

5427-467: The realization that sufficient quantities of aluminum aircraft alloys would be available for war production, plans for large-scale C-76 production were rejected. The Louisville plant was converted to C-46 Commando production, delivering 438 Commandos to supplement the roughly 2,500 C-46s produced at Buffalo. The C-46 cargo aircraft was fitted with two powerful radial engines and could fly at higher altitudes than most other Allied aircraft. Consequently, it

5508-522: The realm of designing aircraft, such as the TDU-12/B Skydart target drone and the X-19 tilt-rotor, but none of these amounted to anything and by the early 1960s Curtiss-Wright was no longer an aircraft manufacturer. While this marked Curtiss-Wright's departure from preeminence in the aviation industry, one notable spin-off involved Curtiss-Wright's flight research laboratory, founded in 1943 near

5589-550: The source). It is estimated that there are about 900,000 km of "unconventional" gas such as shale gas, of which 180,000 km may be recoverable. In turn, many studies from MIT , Black & Veatch and the US Department of Energy predict that natural gas will account for a larger portion of electricity generation and heat in the future. The world's largest gas field is the offshore South Pars / North Dome Gas-Condensate field , shared between Iran and Qatar. It

5670-598: The third peak in December 2019, extraction continued to fall from March onward due to decreased demand caused by the COVID-19 pandemic in the US . The 2021 global energy crisis was driven by a global surge in demand as the world quit the economic recession caused by COVID-19, particularly due to strong energy demand in Asia. Because of its low density, it is not easy to store natural gas or to transport it by vehicle. Natural gas pipelines are impractical across oceans, since

5751-439: The third quarter of 2022. The strategic acquisition of SAA is part of Curtiss-Wright's efforts to enhance growth prospects and diversify its product portfolio. With an anticipated positive impact on CW's earnings, the $ 240 million transaction is projected to contribute to a robust free cash flow conversion rate exceeding 100%, signaling a favorable liquidity position for the company in the future. In November 2022, CW has finalized

5832-412: The transmission line to pressurize and repressurize the mid-stream natural gas as the gas travels. Typically, natural gas powered engines require 35–39 MJ/m (950–1,050 BTU/cu ft) natural gas to operate at the rotational name plate specifications. Several methods are used to remove these higher molecular weighted gases for use by the natural gas engine. A few technologies are as follows: In

5913-584: The war, over 7,000 SB2C Helldivers . Its most visible success came with the P-40, variously known as the Tomahawk, Kittyhawk, and Warhawk, which were built between 1940 and 1944 at the main production facilities in Buffalo, New York . During the war, a second large plant was added at Buffalo, followed by new plants at Columbus, Ohio ; St. Louis, Missouri ; and Louisville, Kentucky . Engine and propeller production

5994-502: The worldwide extraction, access to natural gas has become an important issue in international politics, and countries vie for control of pipelines. In the first decade of the 21st century, Gazprom , the state-owned energy company in Russia, engaged in disputes with Ukraine and Belarus over the price of natural gas, which have created concerns that gas deliveries to parts of Europe could be cut off for political reasons. The United States

6075-518: Was at plants in New Jersey, Pennsylvania, and Ohio. In May 1942, the U.S. government assigned Curtiss-Wright a defense production factory for wartime aircraft construction at Louisville, Kentucky , to produce C-76 Caravan cargo aircraft, which was constructed mostly of wood, a non-priority war material. After difficulties with the C-76, including a crash of a production model in mid-1943, as well as

6156-549: Was especially true in the first two years of the war. Curtiss' failure to research and develop more advanced wing and airframe designs provided an opening for North American , Bell , Lockheed, Northrop, and other U.S. aircraft manufacturers to win contracts from the Army and Navy for more advanced aircraft designs. The P-60 , the firm's last prop-driven fighter design, was merely an extrapolation of its 1930s P-36 Hawk , offering no advantage over other designs already in service. With

6237-565: Was headquartered in Buffalo, New York . With $ 75 million in capital (equivalent to $ 1.33 billion in 2023), it became the largest aviation company in the United States. By September 1929, Curtiss-Wright had acquired the Moth Aircraft Corporation (which primarily built de Havilland Moth aircraft under licence) and the Travel Air Manufacturing Company . There were three main divisions:

6318-494: Was invented in Saudi Arabia in the late 1970s, ending any necessity for flaring. Satellite and nearby infra-red camera observations, however, shows that flaring and venting are still happening in some countries. Natural gas is used to generate electricity and heat for desalination . Similarly, some landfills that also discharge methane gases have been set up to capture the methane and generate electricity. Natural gas

6399-532: Was later revealed that Wright company officials at Lockland had conspired with civilian technical advisers and Army inspection officers to approve substandard or defective aircraft engines for military use. Curtiss-Wright failed to make the transition to design and production of jet aircraft , despite several attempts. During the war, the company expended only small amounts on aircraft research and development, instead concentrating on incremental improvements in conventional aircraft already in wartime production. This

6480-567: Was recovered in the course of recovering petroleum could not be profitably sold, and was simply burned at the oil field in a process known as flaring . Flaring is now illegal in many countries. Additionally, higher demand in the last 20–30 years has made production of gas associated with oil economically viable. As a further option, the gas is now sometimes re- injected into the formation for enhanced oil recovery by pressure maintenance as well as miscible or immiscible flooding. Conservation, re-injection, or flaring of natural gas associated with oil

6561-780: Was used extensively in the China-Burma-India Theater . From 1941 to 1943, the Curtiss Aeronautical plant in Lockland, Ohio , produced aircraft engines under wartime contract, destined for installation in U.S. Army Air Forces aircraft. Wright officials at Lockland insisted on high engine production levels, resulting in a significant percentage of engines that did not meet Army Air Forces (AAF) inspection standards. These defective engines were nevertheless approved by inspectors for shipment and installation in U.S. military aircraft. After investigation, it
