71-409: The Cessna 182 Skylane is an American four-seat, single-engined light airplane built by Cessna of Wichita, Kansas . It has the option of adding two child seats in the baggage area. Introduced in 1956, the 182 has been produced in a number of variants, including a version with retractable landing gear, and is the second-most popular Cessna model still in production after the 172 . The Cessna 182
142-465: A cranked or polyhedral wing the dihedral angle varies along the span. (Note that the description "cranked" varies in usage. See also Cranked arrow planform.) Some designs have no clear join between wing and fuselage, or body. This may be because one or other of these is missing, or because they merge into each other: Some designs may fall into multiple categories depending on interpretation, for example many UAVs or drones can be seen either as
213-399: A basic plane and must then be completed by the builder. Few companies produce planes on a large scale. However, the production of a plane for one company is a process that actually involves dozens, or even hundreds, of other companies and plants, that produce the parts that go into the plane. For example, one company can be responsible for the production of the landing gear, while another one
284-578: A combustion chamber or a solid fuel with oxidizer may burn in the fuel chamber. Whether liquid or solid-fueled, the hot gas is accelerated through a nozzle. In World War II , the Germans deployed the Me 163 Komet rocket-powered aircraft . The first plane to break the sound barrier in level flight was a rocket plane – the Bell X-1 in 1948. The North American X-15 broke many speed and altitude records in
355-646: A different engine, new seating design, etc. By mid-2013, Cessna planned to introduce the next model of the 182T, designated the JT-A, using the 227 hp (169 kW) SMA SR305-230 diesel engine running on Jet-A with a burn rate of 11 U.S. gallons (42 L; 9.2 imp gal) per hour and cruise at 155 kn (287 km/h). Cessna has no timeline for the JT-A. The normally aspirated, avgas -fueled 182 went out of production in 2012, but came back in 2015. Cessna 182s were also built in Argentina by DINFIA , as
426-781: A first flight. The flight tests continue until the aircraft has fulfilled all the requirements. Then, the governing public agency of aviation of the country authorizes the company to begin production. In the United States, this agency is the Federal Aviation Administration (FAA). In the European Union, European Aviation Safety Agency (EASA); in the United Kingdom it is the Civil Aviation Authority (CAA). In Canada,
497-468: A form of roll control supplied either by wing warping or by ailerons and controlled by its pilot with a joystick and rudder bar. It was an important predecessor of his later Blériot XI Channel -crossing aircraft of the summer of 1909. World War I served as a testbed for the use of the airplane as a weapon. Airplanes demonstrated their potential as mobile observation platforms, then proved themselves to be machines of war capable of causing casualties to
568-412: A frame and made rigid by the lift forces exerted by the airflow over them. Larger aircraft have rigid wing surfaces which provide additional strength. Whether flexible or rigid, most wings have a strong frame to give them their shape and to transfer lift from the wing surface to the rest of the aircraft. The main structural elements are one or more spars running from root to tip, and many ribs running from
639-702: A hand pump to pressurize the hydraulic system. The system does not, however, allow the landing gear to be manually retracted. Cessna has historically used model years similar to U.S. auto manufacturers, with sales of new models typically starting a few months prior to the actual calendar year. The 182 is used by a multitude of civil operators, cadet organizations, and flight schools worldwide.

710-414: A jet-powered aircraft with a speed of Mach 9.7, nearly 12,100 kilometers per hour (7,500 mph). Whereas jet aircraft use the atmosphere both as a source of oxidant and of mass to accelerate reactively behind the aircraft, rocket aircraft carry the oxidizer on board and accelerate the burned fuel and oxidizer backwards as the sole source of mass for reaction. Liquid fuel and oxidizer may be pumped into
781-491: A long span from side to side but have a short chord (high aspect ratio ). But to be structurally efficient, and hence light weight, a wing must have a short span but still enough area to provide lift (low aspect ratio). Wing configuration The wing configuration of a fixed-wing aircraft (including both gliders and powered aeroplanes ) is its arrangement of lifting and related surfaces. Aircraft designs are often classified by their wing configuration. For example,

#1732787048182852-551: A presence in all the major battles of World War II . The first jet aircraft was the German Heinkel He 178 in 1939. The first jet airliner , the de Havilland Comet , was introduced in 1952. The Boeing 707 , the first widely successful commercial jet, was in commercial service for more than 60 years, from 1958 to 2019. First attested in English in the late 19th century (prior to the first sustained powered flight),
923-416: A propeller creates is determined, in part, by its disk area—the area through which the blades rotate. The limitation on blade speed is the speed of sound ; as when the blade tip exceeds the speed of sound, shock waves decrease propeller efficiency. The rpm required to generate a given tip speed is inversely proportional to the diameter of the propeller. The upper design speed limit for propeller-driven aircraft
994-477: A shaft through a reduction gearing to the propeller. The propelling nozzle provides a relatively small proportion of the thrust generated by a turboprop. An electric aircraft runs on electric motors with electricity coming from fuel cells , solar cells , ultracapacitors , power beaming , or batteries . Currently, flying electric aircraft are mostly experimental prototypes, including manned and unmanned aerial vehicles , but there are some production models on
1065-462: A side effect. The wing chord may be varied along the span of the wing, for both structural and aerodynamic reasons. Wings may be swept back, or occasionally forwards, for a variety of reasons. A small degree of sweep is sometimes used to adjust the centre of lift when the wing cannot be attached in the ideal position for some reason, such as a pilot's visibility from the cockpit. Other uses are described below. Some types of variable geometry vary
1136-426: A single wing plane, a biplane has two stacked one above the other, a tandem wing has two placed one behind the other. When the available engine power increased during the 1920s and 30s and bracing was no longer needed, the unbraced or cantilever monoplane became the most common form of powered type. The wing planform is the shape when seen from above. To be aerodynamically efficient, a wing should be straight with
1207-435: A small and simple engine for high-speed use, such as with missiles. Ramjets require forward motion before they can generate thrust and so are often used in conjunction with other forms of propulsion, or with an external means of achieving sufficient speed. The Lockheed D-21 was a Mach 3+ ramjet-powered reconnaissance drone that was launched from a parent aircraft . A ramjet uses the vehicle's forward motion to force air through
1278-468: A span of 14 m (46 ft). All-up weight was 300 kilograms (660 lb). On 9 October 1890, Ader attempted to fly the Éole . Aviation historians give credit to this effort as a powered take-off and uncontrolled hop of approximately 50 m (160 ft) at a height of approximately 200 mm (7.9 in). Ader's two subsequent machines were not documented to have achieved flight. The American Wright brothers 's flights in 1903 are recognized by
1349-538: A tailless blended wing-body or as a flying wing with a deep centre chord. A variable geometry aircraft is able to change its physical configuration during flight. Some types of variable geometry craft transition between fixed wing and rotary wing configurations. For more about these hybrids, see powered lift . A polymorphic wing is able to change the number of planes in flight. The Nikitin-Shevchenko IS "folding fighter" prototypes were able to morph between biplane and monoplane configurations after takeoff by folding
1420-461: A type of rotary aircraft engine, he did not create and fly a powered fixed-wing aircraft. The Frenchman Clement Ader constructed his first of three flying machines in 1886, the Éole . It was a bat-like design run by a lightweight steam engine of his own invention, with four cylinders developing 20 horsepower (15 kW ), driving a four-blade propeller . The engine weighed no more than 4 kilograms per kilowatt (6.6 lb/hp). The wings had

Reciprocating engines in aircraft have three main variants, radial , in-line and flat or horizontally opposed engine . The radial engine is a reciprocating type internal combustion engine configuration in which the cylinders "radiate" outward from a central crankcase like the spokes of a wheel and was commonly used for aircraft engines before gas turbine engines became predominant. An inline engine

A flat engine is an internal combustion engine with horizontally-opposed cylinders. A turboprop gas turbine engine consists of an intake, compressor, combustor, turbine, and a propelling nozzle, which provide power from
1704-484: Is common to refer to a plane as a wing, as in "a biplane has two wings", or alternatively to refer to the whole thing as a wing, as in "a biplane wing has two planes". Where the meaning is clear, this article follows common usage, only being more precise where needed to avoid real ambiguity or incorrectness. Fixed-wing aircraft can have different numbers of wings: A fixed-wing aircraft may have more than one wing plane, stacked one above another: A staggered design has
1775-420: Is less than 1% of the world's cargo movement. Most airplanes are flown by a pilot on board the aircraft, but some are designed to be remotely or computer-controlled such as drones. The Wright brothers invented and flew the first airplane in 1903, recognized as "the first sustained and controlled heavier-than-air powered flight". They built on the works of George Cayley dating from 1799, when he set forth
1846-438: Is particularly so for variable geometry and combined (closed) wing types. Most of the configurations described here have flown (if only very briefly) on full-size aircraft. A few theoretical designs are also notable. Note on terminology: Most fixed-wing aircraft have left hand and right hand wings in a symmetrical arrangement. Strictly, such a pair of wings is called a wing plane or just plane. However, in certain situations it

The production of such parts is not limited to the same city or country; in the case of large plane manufacturing companies, such parts can come from all over the world. The parts are sent to the main plant of the plane company, where the production line is located. In the case of large planes, production lines dedicated to the assembly of certain parts of the plane can exist, especially
1988-408: Is the silhouette of the wing when viewed from above or below. See also variable geometry types which vary the wing planform during flight. The aspect ratio is the span divided by the mean or average chord. It is a measure of how long and slender the wing appears when seen from above or below. Most variable geometry configurations vary the aspect ratio in some way, either deliberately or as
2059-580: The Fédération Aéronautique Internationale (FAI), the standard-setting and record-keeping body for aeronautics , as "the first sustained and controlled heavier-than-air powered flight". By 1905, the Wright Flyer III was capable of fully controllable, stable flight for substantial periods. The Wright brothers credited Otto Lilienthal as a major inspiration for their decision to pursue manned flight. In 1906,
2130-488: The Beechcraft Staggerwing . To support itself a wing has to be rigid and strong and consequently may be heavy. By adding external bracing, the weight can be greatly reduced. Originally such bracing was always present, but it causes a large amount of drag at higher speeds and has not been used for faster designs since the early 1930s. The types are: Wings can also be characterised as: The wing planform
2201-621: The Supermarine Spitfire is a conventional low wing cantilever monoplane of straight elliptical planform with moderate aspect ratio and slight dihedral. Many variations have been tried. Sometimes the distinction between them is blurred, for example the wings of many modern combat aircraft may be described either as cropped compound deltas with (forwards or backwards) swept trailing edge, or as sharply tapered swept wings with large leading edge root extensions (or LERX). Some are therefore duplicated here under more than one heading. This

Leonardo da Vinci researched the wing design of birds and designed a man-powered aircraft in his Codex on the Flight of Birds (1502), noting for the first time the distinction between the center of mass and the center of pressure of flying birds. In 1799, George Cayley set forth the concept of
2343-605: The 1920s and 30s, wings could be made heavy and strong enough that bracing was not needed any more. This type of unbraced wing is called a cantilever wing. The number and shape of the wings varies widely on different types. A given wing plane may be full-span or divided by a central fuselage into port (left) and starboard (right) wings. Occasionally, even more wings have been used, with the three-winged triplane achieving some fame in WWI. The four-winged quadruplane and other multiplane designs have had little success. A monoplane has

The Cessna 182 is an all-metal (mostly aluminum alloy) aircraft, although some parts – such as engine cowling nosebowl and wingtips – are made of fiberglass or thermoplastic material. Its wing has the same planform as the smaller Cessna 172 and the larger 205/206 series; however, some wing details, such as flap and aileron design, are
2556-742: The Brazilian Alberto Santos-Dumont made what was claimed to be the first airplane flight unassisted by catapult and set the first world record recognized by the Aéro-Club de France by flying 220 meters (720 ft) in less than 22 seconds. This flight was also certified by the FAI. An early aircraft design that brought together the modern monoplane tractor configuration was the Blériot VIII design of 1908. It had movable tail surfaces controlling both yaw and pitch,
2627-634: The Cessna 182 is the R182. Cessna gave the R182 the marketing name of "Skylane RG". The R182 and TR182 offer 10-15% improvement in climb and cruise speeds over their fixed-gear counterparts, or alternatively, 10-15% better fuel economy at the same speeds at the expense of increased maintenance costs and decreased gear robustness. The 1978 R182 has a sea-level climb rate of 1140 ft/min and cruising speed (75% BHP) at 7,500 feet (2,300 m) of 156 KTAS at standard temperature. The landing-gear retraction system in

An aircraft propeller , or airscrew , converts rotary motion from an engine or other power source, into a swirling slipstream which pushes the propeller forwards or backwards. It comprises a rotating power-driven hub, to which are attached two or more radial airfoil -section blades such that the whole assembly rotates about a longitudinal axis. Three types of aviation engines used to power propellers include reciprocating engines (or piston engines), gas turbines , and electric motors . The amount of thrust

Other aviators who made similar flights at that time were Otto Lilienthal , Percy Pilcher , and Octave Chanute . Sir Hiram Maxim built a craft that weighed 3.5 tons, with a 110-foot (34 m) wingspan that was powered by two 360-horsepower (270 kW) steam engines driving two propellers. In 1894, his machine

The system includes a gear position warning that emits an intermittent tone through the cabin speaker when the gear is in the retracted position and either the throttle is reduced below about 12 inHg manifold pressure MAP) or the flaps are extended beyond 20°. In the event of a hydraulic pump failure, the landing gear may be lowered using
2911-485: The air entering the engine must be decelerated to a subsonic speed and then re-accelerated back to supersonic speeds after combustion. An afterburner may be used on combat aircraft to increase power for short periods of time by injecting fuel directly into the hot exhaust gases. Many jet aircraft also use thrust reversers to slow down after landing. A ramjet is a form of jet engine that contains no major moving parts and can be particularly useful in applications requiring

2982-437: The behavior of the aircraft. Computers are used by companies to draw, plan and do initial simulations of the aircraft. Small models and mockups of all or certain parts of the plane are then tested in wind tunnels to verify its aerodynamics. When the design has passed through these processes, the company constructs a limited number of prototypes for testing on the ground. Representatives from an aviation governing agency often make
3053-906: The case of international sales, a license from the public agency of aviation or transport of the country where the aircraft is to be used is also necessary. For example, airplanes made by the European company, Airbus , need to be certified by the FAA to be flown in the United States, and airplanes made by U.S.-based Boeing need to be approved by the EASA to be flown in the European Union. Regulations have resulted in reduced noise from aircraft engines in response to increased noise pollution from growth in air traffic over urban areas near airports. Small planes can be designed and constructed by amateurs as homebuilts. Other homebuilt aircraft can be assembled using pre-manufactured kits of parts that can be assembled into

Most jet aircraft use turbofan jet engines, which employ a gas turbine to drive a ducted fan, which accelerates air around the turbine to provide thrust in addition to that which is accelerated through the turbine. The ratio of air passing around

In the 1890s, Lawrence Hargrave conducted research on wing structures and developed a box kite that lifted the weight of a man. His box kite designs were widely adopted. Although he also developed
3337-479: The end of WWII all-metal aircraft were common. In modern times, increasing use of composite materials has been made. Typical structural parts include: The wings of a fixed-wing aircraft are static planes extending either side of the aircraft. When the aircraft travels forwards, air flows over the wings, which are shaped to create lift. This shape is called an airfoil and is shaped like a bird's wing. Airplanes have flexible wing surfaces which are stretched across
3408-537: The enemy. The earliest known aerial victory with a synchronized machine gun-armed fighter aircraft occurred in 1915, by German Luftstreitkräfte Leutnant Kurt Wintgens . Fighter aces appeared; the greatest (by number of Aerial Combat victories) was Manfred von Richthofen , also known as the Red Baron. Following WWI, aircraft technology continued to develop. Alcock and Brown crossed the Atlantic non-stop for

A scramjet is a specialized ramjet that uses internal supersonic airflow to compress, combine with fuel, combust and accelerate the exhaust to provide thrust. The engine operates at supersonic speeds only. The NASA X-43 , an experimental unmanned scramjet, set a world speed record in 2004 for
3550-628: The first time in 1919. The first international commercial flights took place between the United States and Canada in 1919. Airplanes had a presence in all the major battles of World War II . They were an essential component of the military strategies of the period, such as the German Blitzkrieg , The Battle of Britain , and the American and Japanese aircraft carrier campaigns of the Pacific War . The first practical jet aircraft
3621-465: The horizontal stabilizer. Angling the wings up or down spanwise from root to tip can help to resolve various design issues, such as stability and control in flight. Some biplanes have different degrees of dihedral/anhedral on different wings. The Sopwith Camel had a flat upper wing and dihedral on the lower wing, while the Hanriot HD-1 had dihedral on the upper wing but none on the lower. In

#17327870481823692-399: The leading (front) to the trailing (rear) edge. Early airplane engines had little power, and lightness was very important. Also, early airfoil sections were very thin, and could not have a strong frame installed within. So, until the 1930s, most wings were too lightweight to have enough strength, and external bracing struts and wires were added. When the available engine power increased during
3763-453: The lower wing up into a cavity in the underside of the upper wing. The slip wing is a variation on the polymorphic idea, in which a low-wing monoplane is fitted with a second detachable "slip" wing above it to assist takeoff. The upper wing is then released and discarded once in the air. The idea was first flown on the experimental Hillson Bi-mono . Aircraft may have additional minor aerodynamic surfaces. Some of these are treated as part of
3834-422: The manufacturer or the customer. The structural parts of a fixed-wing aircraft are called the airframe. The parts present can vary according to the aircraft's type and purpose. Early types were usually made of wood with fabric wing surfaces, When engines became available for powered flight around a hundred years ago, their mounts were made of metal. Then as speeds increased more and more parts became metal until by
3905-440: The market. Jet aircraft are propelled by jet engines , which are used because the aerodynamic limitations of propellers do not apply to jet propulsion. These engines are much more powerful than a reciprocating engine for a given size or weight and are comparatively quiet and work well at higher altitude. Variants of the jet engine include the ramjet and the scramjet , which rely on high airspeed and intake geometry to compress
3976-406: The modern airplane as a fixed-wing flying machine with separate systems for lift, propulsion, and control. Cayley was building and flying models of fixed-wing aircraft as early as 1803, and he built a successful passenger-carrying glider in 1853. In 1856, Frenchman Jean-Marie Le Bris made the first powered flight, by having his glider "L'Albatros artificiel" pulled by a horse on a beach. Then
4047-405: The objective of producing them in quantity for customers. The design and planning process, including safety tests, can last up to four years for small turboprops or longer for larger planes. During this process, the objectives and design specifications of the aircraft are established. First the construction company uses drawings and equations, simulations, wind tunnel tests and experience to predict
4118-429: The overall wing configuration: Additional minor features may be applied to an existing aerodynamic surface such as the main wing: High-lift devices maintain lift at low speeds and delay the stall to allow slower takeoff and landing speeds: On a swept wing, air tends to flow sideways as well as backwards and reducing this can improve the efficiency of the wing: Vortex devices maintain airflow at low speeds and delay
4189-586: The public agency in charge and authorizing the mass production of aircraft is Transport Canada's Civil Aviation Authority. When a part or component needs to be joined together by welding for virtually any aerospace or defense application, it must meet the most stringent and specific safety regulations and standards. Nadcap , or the National Aerospace and Defense Contractors Accreditation Program sets global requirements for quality, quality management and quality assurance for aerospace engineering. In

The model designation nomenclature differs from some other Cessna models with optional retractable gear. For instance, the retractable version of the Cessna 172 was designated as the 172RG and the 177RG , whereas the retractable gear version of
4331-619: The term "airplane" is used for powered fixed-wing aircraft. In the United Kingdom and Ireland and most of the Commonwealth , the term "aeroplane" ( / ˈ ɛər ə p l eɪ n / ) is usually applied to these aircraft. Many stories from antiquity involve flight, such as the Greek legend of Icarus and Daedalus , and the Vimana in ancient Indian epics . Around 400 BC in Greece , Archytas

They represent a compromise between turbojet (with no bypass) and turboprop forms of aircraft propulsion (primarily powered with bypass air). Subsonic aircraft, such as airliners, employ high by-pass jet engines for fuel efficiency. Supersonic aircraft , such as jet fighters, use low-bypass turbofans. However at supersonic speeds,

Long thought to reduce the interference caused by the low pressure air over the lower wing mixing with the high pressure air under the upper wing; however the improvement is minimal and its primary benefit is to improve access to the fuselage. It is common on many successful biplanes and triplanes. Backwards stagger is also seen in a few examples such as

Also it cannot provide any significant pitch control, requiring a separate control surface (elevator) mounted elsewhere - usually on
4615-408: The wings and the fuselage. When complete, a plane is rigorously inspected to search for imperfections and defects. After approval by inspectors, the plane is put through a series of flight tests to assure that all systems are working correctly and that the plane handles properly. To meet a particular customer need, the airplane may be customised using components or packages of components provided by
4686-481: The word airplane , like aeroplane , derives from the French aéroplane , which comes from the Greek ἀήρ ( aēr ), "air" and either Latin planus , "level", or Greek πλάνος ( planos ), "wandering". " Aéroplane " originally referred just to the wing, as it is a plane moving through the air. In an example of synecdoche , the word for the wing came to refer to the entire aircraft. In the United States and Canada,
4757-548: Was introduced in 1956 as a tricycle gear variant of the 180 . In 1957, the 182A variant was introduced, followed by a deluxe version the following year known as the Skylane . As production continued, later models were improved regularly with features such as a wider fuselage, swept tailfin with rear "omni-vision" window, enlarged baggage compartment, higher gross weights, landing gear changes, etc. The "restart" aircraft built after 1996 were different in many other details including

The craft was uncontrollable and it is presumed that Maxim realized this because he subsequently abandoned work on it. Between 1867 and 1896, the German pioneer of human aviation Otto Lilienthal developed heavier-than-air flight. He was the first person to make well-documented, repeated, successful gliding flights. Lilienthal's work led to him developing
