Supersonic speed is the speed of an object that exceeds the speed of sound ( Mach 1). For objects traveling in dry air of a temperature of 20 °C (68 °F) at sea level , this speed is approximately 343.2 m/s (1,126 ft/s; 768 mph; 667.1 kn; 1,236 km/h). Speeds greater than five times the speed of sound (Mach 5) are often referred to as hypersonic . Flights during which only some parts of the air surrounding an object, such as the ends of rotor blades, reach supersonic speeds are called transonic . This occurs typically somewhere between Mach 0.8 and Mach 1.2.
87-545: The Lockheed D-21 is an American supersonic reconnaissance drone . The D-21 was initially designed to be launched from the back of an M-21 carrier aircraft, a variant of the Lockheed A-12 aircraft. The drone had maximum speed in excess of Mach 3.3 (2,200 miles per hour; 3,600 kilometers per hour) at an operational altitude of 90,000 feet (27,000 meters). Development began in October 1962. Originally known by
174-665: A Boeing B-52 Stratofortress . Several successful test flights were made, followed by at least four unsuccessful operational D-21 flights over China, before the program was canceled in 1971. In the 1960s, Lockheed's secret Skunk Works developed the Mach 3 A-12 reconnaissance aircraft for the Central Intelligence Agency (CIA). After the shooting down of the U-2 piloted by Gary Powers in 1960, several different concepts were proposed as alternatives. Kelly Johnson ,
261-540: A Fortune 500 company, ranked 115th in 2023. In 2023, the corporation had a global workforce of approximately 95,000 employees. The current chairman & chief executive officer (CEO) is Vimal Kapur . The corporation's current name, Honeywell International Inc., is a product of the merger of Honeywell Inc. and AlliedSignal in 1999. The corporation headquarters were consolidated with AlliedSignal's headquarters in Morristown, New Jersey. The combined company chose
348-733: A player piano to relay instructions to the aircraft's autopilot at certain way points during the flight, significantly reducing the pilot's workload. Technologically, this effort had parallels to contemporary efforts in missile guidance and numerical control . Honeywell also developed the Wagtail missile with the USAF. From the 1950s until the mid-1970s, Honeywell was the United States' importer of Japanese company Asahi Optical's Pentax cameras and photographic equipment. These products were labeled "Heiland Pentax" and "Honeywell Pentax" in
435-643: A "patent cross-license" agreement that "fully resolves" the long-standing dispute. Honeywell sued Nest Labs in 2012. In 2017, Honeywell opened a new software center in Atlanta, Georgia. David Cote stepped down as CEO on April 1, 2017, and was succeeded by Darius Adamczyk , who had been promoted to president and chief operating officer (COO) in 2016. Cote served as executive chairman to April 2018. In October 2017, Honeywell announced plans to spin off its Homes, ADI Global Distribution , and Transportation Systems businesses into two separate, publicly traded companies by
522-647: A Japan-based distributor. Later in 1934, Minneapolis-Honeywell started distributorships across Canada, as well as one in the Netherlands, their first European office. This expansion into international markets continued in 1936, with their first distributorship in London, as well as their first foreign assembly facility being established in Canada. By 1937, ten years after the merger, Minneapolis-Honeywell had over 3,000 employees, with $ 16 million in annual revenue. With
609-494: A better position in those markets. Under Binger's stewardship from 1961 to 1978 he expanded the company into such fields as defense, aerospace, and computing. During and after the Vietnam Era , Honeywell's defense division produced a number of products, including cluster bombs , missile guidance systems, napalm , and land mines . Minnesota-Honeywell Corporation completed flight tests on an inertia guidance sub-system for
696-548: A cramped "Q-bay" below the drone's air intake . These components were built into a module that fit into the bay and was known as a "hatch". The hatch would be ejected at the end of the mission and then snagged out of the air by a JC-130 Hercules , a technique that had been developed by the USAF to recover film canisters from balloons and satellites. If the C-130 missed, the hatch was equipped with flotation devices so it could be recovered by ship if released over water. Honeywell built
783-603: A definitive agreement to acquire Xtralis, a leading global provider of aspirating smoke detection along with advanced perimeter security technologies and video analytics software, for $ 480 million, from funds advised by Pacific Equity Partners and Blum Capital Partners. The deal was completed in April 2016. In May 2016, Honeywell International Inc. settled its patent dispute regarding Google subsidiary Nest Labs, whose thermostats Honeywell claimed infringed on several of its patents. Google parent Alphabet Inc. and Honeywell said they reached
870-402: A global joint venture with Compagnie des Machines Bull of France and NEC Corporation of Japan to become Honeywell Bull. In 1988 Honeywell Bull was consolidated into Groupe Bull and in 1989 renamed to Bull, a Worldwide Information Systems Company. By 1991, Honeywell was no longer involved in the computer business. 1986 marked a new direction for Honeywell, beginning with the acquisition of
957-460: A half at high altitudes. The modified engine was designated RJ43-MA20S-4 . A full-scale mockup of the Q-12 was ready by 7 December 1962, and had already undergone preliminary tests to measure its radar cross-section. Marquardt had also successfully tested the modified RJ-43 in its wind tunnel in the meantime. The CIA was not enthusiastic about the Q-12, mostly because the agency was overextended at

Sweatt survived rough spots and turned an innovative idea – thermostatic heating control – into a thriving business. Harold took over in 1934, leading Honeywell through
1479-658: A period of growth and global expansion that set the stage for Honeywell to become a global technology leader. The merger into the Minneapolis-Honeywell Regulator Company proved to be a saving grace for the corporation. 1934 marked Minneapolis-Honeywell's first foray into the international market, when they acquired the Brown Instrument Company and inherited their relationship with the Yamatake Company of Tokyo,
1566-430: A stripped nut on the pylon before the aircraft reached its intended launch point. Johnson admitted that the incident was "very embarrassing". Three more launches were performed from November 1967 to January 1968. None were completely successful, so Johnson ordered his team to conduct a thorough review before renewing launch attempts. The next launch was on 10 April 1968. It also failed as the engine did not ignite. On 16 June
1653-614: A £1.2bn ($ 2.3bn) bid for Novar plc in December 2004. The acquisition was finalized in March 2005. In October 2005, Honeywell bought out Dow's 50% stake in UOP for $ 825 million, giving them complete control over the joint venture in petrochemical and refining technology. In May 2010, Honeywell outbid UK-based Cinven and acquired the French company Sperian Protection for $ 1.4 billion, which

#17327767505911914-428: Is crack formation faster than the speed of sound in a brittle material. The word supersonic comes from two Latin derived words ; 1) super : above and 2) sonus : sound, which together mean above sound, or faster than sound. At the beginning of the 20th century, the term "supersonic" was used as an adjective to describe sound whose frequency is above the range of normal human hearing. The modern term for this meaning
2001-444: Is more complex. The main key to having low supersonic drag is to properly shape the overall aircraft to be long and thin, and close to a "perfect" shape, the von Karman ogive or Sears-Haack body . This has led to almost every supersonic cruising aircraft looking very similar to every other, with a very long and slender fuselage and large delta wings, cf. SR-71 , Concorde , etc. Although not ideal for passenger aircraft, this shaping

No modern-day passenger aircraft are capable of supersonic speed, but there have been supersonic passenger aircraft , namely Concorde and the Tupolev Tu-144 . Both of these passenger aircraft and some modern fighters are also capable of supercruise , a condition of sustained supersonic flight without
2262-559: The Electric Heat Regulator Company now-renamed Minneapolis Heat Regulator Company. In 1927, this led to the merging of both companies into the publicly-held Minneapolis-Honeywell Regulator Company. Honeywell was named the company's first president, alongside W.R. Sweatt as its first chairman. In 1929, combined assets were valued at over $ 3.5 million, with less than $ 1 million in liabilities just months before Black Monday . In 1931, Minneapolis-Honeywell began
2349-561: The European Commission 's competition commissioner, Mario Monti , blocked the move. This decision was taken on the grounds that with GE's dominance of the large jet engine market, led by the General Electric CF34 turbofan engine, its leasing services ( GECAS ), and Honeywell's portfolio of regional jet engines and avionics , the new company would be able to "bundle" products and stifle competition through

The Butz Thermo-Electric Regulator Company was founded in 1885 when the Swiss-born Albert Butz invented the damper-flapper , a thermostat used to control coal furnaces, bringing automated heating system regulation into homes. In 1886, he founded the Butz Thermo-Electric Regulator Company. In 1888, after a falling out with his investors, Butz left
2523-727: The RUR-5 ASROC for the US Navy. In 1953, in cooperation with the USAF Wright-Air Development Center, Honeywell developed an automated control unit, that could control an aircraft through various stages of a flight, from taxiing to takeoff to the point where the aircraft neared its destination and the pilot took over for landing . Called the Automatic Master Sequence Selector , the onboard control operated similarly to

The vehicle, driven by Andy Green , holds the world land speed record, having achieved an average speed on its bi-directional run of 1,228 km/h (763 mph) in the Black Rock Desert on 15 October 1997. The Bloodhound LSR project planned an attempt on the record in 2020 at Hakskeenpan in South Africa with a combination jet and hybrid rocket propelled car. The aim was to break
2697-562: The Tupolev Tu-160 and Rockwell B-1 Lancer are also supersonic-capable. The aerodynamics of supersonic aircraft is simpler than subsonic aerodynamics because the airsheets at different points along the plane often cannot affect each other. Supersonic jets and rocket vehicles require several times greater thrust to push through the extra aerodynamic drag experienced within the transonic region (around Mach 0.85–1.2). At these speeds aerospace engineers can gently guide air around

Designers use the Supersonic area rule and the Whitcomb area rule to minimize sudden changes in size. However, in practical applications, a supersonic aircraft must operate stably in both subsonic and supersonic profiles, hence aerodynamic design
3132-467: The speed of sound decreases somewhat with altitude, due to lower temperatures found there (typically up to 25 km). At even higher altitudes the temperature starts increasing, with the corresponding increase in the speed of sound. When an inflated balloon is burst, the torn pieces of latex contract at supersonic speed, which contributes to the sharp and loud popping noise. To date, only one land vehicle has officially travelled at supersonic speed,
3219-546: The wave motion travelling through the bullwhip that makes it capable of achieving supersonic speeds. Most modern firearm bullets are supersonic, with rifle projectiles often travelling at speeds approaching and in some cases well exceeding Mach 3 . Most spacecraft are supersonic at least during portions of their reentry, though the effects on the spacecraft are reduced by low air densities. During ascent, launch vehicles generally avoid going supersonic below 30 km (~98,400 feet) to reduce air drag. Note that
3306-777: The 1960s, Honeywell was one of the " Snow White and the Seven Dwarfs " of computing. IBM was "Snow White", while the dwarfs were the seven significantly smaller computer companies: Burroughs , Control Data Corporation , General Electric , Honeywell, NCR , RCA , and UNIVAC . Later, when their number had been reduced to five, they were known as "The BUNCH ", after their initials: Burroughs, UNIVAC, NCR, Control Data Corporation, and Honeywell. In 1970, Honeywell acquired GE's computer business, rebadging General Electric 's 600-series mainframes to Honeywell 6000 series computers, supporting GCOS , Multics , and CP-6 , while forming Honeywell Information Systems . In 1973, they shipped

The fourth, and last, Senior Bowl flight was on 20 March 1971. It was lost over China on the final segment of the route over China's Yunnan province ; wreckage was found by local authorities. In 2010, after being in
5916-400: The home comfort sector. Honeywell is in the consortium that runs the Pantex Plant that assembles all of the nuclear bombs in the United States arsenal. Honeywell Federal Manufacturing & Technologies, successor to the defense products of AlliedSignal, operates the Kansas City Plant which produces and assembles 85 percent of the non-nuclear components of the bombs. Honeywell began
6003-453: The junkyard of the China Aviation Museum for years, the wreckage was moved to the exhibition area. According to writer Lloyd Spanberger, at least two additional operational D-21B flights may have been made. Spanberger cites an interview with Lt. Col. Alfred Crane, who worked with classified spy satellites and drones during the Cold War , in which Crane described processing two D-21B film capsules, both from flights over China. In both cases,
6090-432: The leader of Skunk Works, developed the concept of a long-range drone that used much of the A-12's technology. In October 1962, the CIA and the United States Air Force (USAF) instructed Lockheed to study a high-speed, high-altitude drone concept. Johnson specified speeds of Mach 3.3–3.5, an operational altitude of 87,000–95,000 feet (27,000–29,000 m), and a range of 3,000 nautical miles (3,500 mi; 5,600 km). It
6177-475: The majority were forced to find new jobs or retire. Soon after the merger, the company's stock fell significantly, and did not return to its pre-merger level until 2007. In 2000, the new Honeywell acquired Pittway for $ 2.2 billion to gain a greater share of the fire-protection and security systems market, and merged it into their Home and Building Control division, taking on Pittway's $ 167 million in debt. Analyst David Jarrett commented that "while Honeywell offered
6264-563: The medium. In gases, sound travels longitudinally at different speeds, mostly depending on the molecular mass and temperature of the gas, and pressure has little effect. Since air temperature and composition varies significantly with altitude, the speed of sound, and Mach numbers for a steadily moving object may change. In water at room temperature supersonic speed means any speed greater than 1,440 m/s (4,724 ft/s). In solids, sound waves can be polarized longitudinally or transversely and have higher velocities. Supersonic fracture
6351-582: The name "Honeywell" because of the considerable brand recognition. Honeywell was a component of the Dow Jones Industrial Average index from 1999 to 2008. Prior to 1999, its corporate predecessors were included dating back to 1925, including early entrants in the computing and thermostat industries. In 2020, Honeywell rejoined the Dow Jones Industrial Average index. In 2021, it moved its stock listing from
6438-659: The outbreak of World War II , Minneapolis-Honeywell was approached by the US military for engineering and manufacturing projects. In 1941, Minneapolis-Honeywell developed a superior tank periscope, camera stabilizers, and the C-1 autopilot. The C-1 revolutionized precision bombing and was ultimately used on the two B-29 bombers that dropped atomic bombs on Japan in 1945. The success of these projects led Minneapolis-Honeywell to open an Aero division in Chicago on October 5, 1942. This division
6525-547: The remaining shares of the company from the other stockholders. In 1906, Mark Honeywell founded the Honeywell Heating Specialty Company in Wabash , Indiana , to manufacture and market his invention, the mercury seal generator. As Honeywell's company grew, thanks in part to the acquisition of Jewell Manufacturing Company in 1922 to better automate his heating system, it began to clash with
6612-496: The three previous launches this one was performed straight and level, not in an outside loop to assist in the separation of the drone from the aircraft. The D-21 suffered an engine unstart and struck the M-21's tail after separation, leading to the destruction of both aircraft. The two crew ejected and landed at sea. The pilot, Bill Park, survived, but the Launch Control Officer, Ray Torrick, drowned. Following
6699-507: The time with U-2 missions, getting the A-12 up to speed and covert operations in Southeast Asia. The USAF was interested in the Q-12 as both a reconnaissance platform and a cruise missile and the CIA finally decided to work with the USAF to develop the new drone. Lockheed was awarded a contract in March 1963 for full-scale development of the Q-12. The camera and its film magazines with an inertial navigation system were carried in
6786-405: The use of an afterburner . Due to its ability to supercruise for several hours and the relatively high frequency of flight over several decades, Concorde spent more time flying supersonically than all other aircraft combined by a considerable margin. Since Concorde's final retirement flight on November 26, 2003, there are no supersonic passenger aircraft left in service. Some large bombers , such as
6873-436: Was a two-seat version of the A-12, with a pylon on the fuselage centerline between the vertical stabilizers to carry the drone in a nose-up attitude. A D-21 mounted on an M-21 began captive flight-testing on 22 December 1964. Aerodynamic covers were initially placed over the D-21's intake and exhaust to reduce drag , but had to be removed after the first few tests, as no way of discarding them at Mach 3 without damaging
6960-556: Was acquired by AlliedSignal , who elected to retain the Honeywell name for its brand recognition. The former Honeywell moved their headquarters of 114 years to AlliedSignal's in Morristown , New Jersey . While "technically, the deal looks more like an acquisition than a merger...from a strategic standpoint, it is a merger of equals." AlliedSignal's 1998 revenue was reported at $ 15.1 billion to Honeywell's $ 8.4 billion, but together
7047-404: Was firing. The booster had a burn time of 87 seconds and a thrust of 27,300 pounds-force (121 kN). During ground handling everyone within 25 feet (7.6 m) was required to wear anti-static straps to prevent any discharge of static electricity that might ignite the booster. The first attempted launch of a D-21B was on 28 September 1967, but the drone fell off the B-52's launch pylon due to
7134-557: Was increased in size by approximately 20%. The modified drone version was designated D-21B (there was no D-21A ). Two B-52Hs were modified to carry two drones each by means of two large underwing pylons that replaced the smaller pylons used for the AGM-28 Hound Dog cruise missiles. The tail gunner 's and electronic warfare officer's stations were replaced with two launch control stations. Command and telemetry systems were added, and high-speed cameras were installed to track
7221-403: Was intended to make a one-way trip, eject its camera payload at the end of the mission for recovery, then self-destruct. It had a double- delta wing similar to the A-12's wing design. The Q-12 was to be air-launched from the back of an A-12, and used key technology from the A-12 project, including titanium construction and radar cross-section reduction design features. Johnson wanted to power
7308-494: Was lost due to a hydraulic pump failure after a flight of over 1,200 nmi (1,400 mi; 2,200 km). The USAF's interest in the program continued and more D-21s were ordered after the second launch. A third flight took place on 16 June with the D-21 flying 1,550 nmi (1,800 mi; 2,900 km) through its complete flight profile; its camera hatch was not released due to an electronics failure. The fourth and final launch from an M-21 on 30 July ended in disaster. Unlike
7395-449: Was responsible for the development of the formation stick to control autopilots, more accurate fuel quantity indicators for aircraft, and the turbo supercharger. In 1950, Minneapolis-Honeywell's Aero division was contracted for the controls on the first US nuclear submarine, USS Nautilus . In 1951, the company acquired Intervox Company for their sonar, ultrasonic, and telemetry technologies. Honeywell also helped develop and manufacture
7482-473: Was then incorporated into its automation and controls safety unit. In 2015, the headquarters were moved to Morris Plains, New Jersey . The 475,000-square-foot building on 40 acres in Morris Plains featured state-of-the-art technology and greater energy efficiency than Honeywell's Morristown campus, which was underutilized, outdated and costly, according to Cote. In December 2015, Honeywell completed
7569-660: Was valued at over US$ 113.25 billion in September 2020. Honeywell relocated its corporate headquarters in October 2019 to Charlotte, North Carolina. In July 2019, Honeywell moved employees into a temporary headquarters building in Charlotte before their new building was complete. Honeywell Forge launched as an analytics platform software for industrial and commercial applications such as aircraft, building, industrial, worker and cyber-security. In collaboration with Carnegie Mellon University National Robotics Engineering Center,
