Learjet Aircraft
Learjet was a manufacturer of business jets for civilian and military use based in Wichita, Kansas, United States. Founded in the late 1950s by William Powell Lear as Swiss American Aviation Corporation, it became a subsidiary of Canadian Bombardier Aerospace in 1990, which marketed the company’s aircraft as the "Bombardier Learjet Family". The 3,000th Learjet was delivered in June 2017. The Learjet line was once sufficiently popular that the Learjet name became synonymous and interchangeable with the terms business jet or private jet in the popular vernacular. In February 2021, Bombardier announced the end of production for all new Learjet aircraft in 2021, with the continuation of support and maintenance for aircraft currently in service. History Learjet was one of the first companies to manufacture a private, luxury aircraft. Lear's preliminary design was based upon an experimental American military aircraft known as the Marvel, substituting fuselage-mounted turbojet engi ...

Bombardier Aerospace
Bombardier Aviation, a division of Bombardier Inc., is headquartered in Dorval, Quebec, Canada. The company currently produces the Global and Challenger series of business jets. At its peak, Bombardier operated manufacturing plants in 27 countries and employed over 70,000 workers. However, under financial pressure, it significantly reduced its workforce and divested its entire commercial aircraft portfolio including the Q-Series regional turboprop, CRJ-Series of regional jets, and the C-Series narrowbody jet. History Early activities Bombadier acquired the state-owned Canadair from the government of Canada in 1986 and restored it to profitability. Canadair had been nationalized in 1976. In 1989, Bombardier acquired the near-bankrupt Short Brothers aircraft manufacturing company in Belfast, Northern Ireland. This was followed in 1990 by the acquisition of the bankrupt American company Learjet, a manufacturer of business jets headquartered in Wichita, Kansas. ...

Landing Gear
Landing gear is the undercarriage of an aircraft or spacecraft that is used for taxiing, takeoff or landing. For aircraft, it is generally needed for all three of these. It was also formerly called ''alighting gear'' by some manufacturers, such as the Glenn L. Martin Company. For aircraft, Stinton makes the terminology distinction ''undercarriage (British) = landing gear (US)''. For aircraft, the landing gear supports the craft when it is not flying, allowing it to take off, land, and taxi without damage. Wheeled landing gear is the most common, with skis or Seaplane, floats needed to operate from snow/ice/water and skids for vertical operation on land. Retractable undercarriages fold away during flight, which reduces drag (physics), drag, allowing for faster airspeeds. Landing gear must be strong enough to support the aircraft and its design affects the weight, balance and performance. It often comprises three wheels, or wheel-sets, giving a tripod effect.

Learjet 35
The Learjet Model 35 and Model 36 are a series of American multi-role business jets and military transport aircraft manufactured by Learjet between 1973 and 1993. When used by the United States Air Force, they carry the designation C-21A. Learjet was acquired by Bombardier Aviation in 1990 and is now a subsidiary, so the aircraft is also known as the Bombardier Learjet 35. When first released in 1973, the Learjet 35 was among the fastest medium haul jets of its era. As of 2020, more Learjet 35s have been sold than any other Learjet aircraft, with many still in service after 50 years. The aircraft are powered by two Garrett TFE731-2 turbofan engines. Its cabin can be arranged for six to eight passengers. The longer-range Model 36 has a shortened passenger area to provide more space in the aft fuselage for fuel tanks. The engines are mounted in nacelles on the sides of the aft fuselage. The wings are equipped with single-slotted flaps. The wingtip fuel tanks distinguish the d ...

Turbofan
A turbofan or fanjet is a type of airbreathing jet engine that is widely used in aircraft engine, aircraft propulsion. The word "turbofan" is a combination of references to the preceding generation engine technology of the turbojet and the additional fan stage. It consists of a gas turbine engine which achieves mechanical energy from combustion, and a ducted fan that uses the mechanical energy from the gas turbine to force air rearwards. Thus, whereas all the air taken in by a turbojet passes through the combustion chamber and turbines, in a turbofan some of that air bypasses these components. A turbofan thus can be thought of as a turbojet being used to drive a ducted fan, with both of these contributing to the thrust. The ratio of the mass-flow of air bypassing the engine core to the mass-flow of air passing through the core is referred to as the bypass ratio. The engine produces thrust through a combination of these two portions working together. Engines that use more Propel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Honeywell TFE731
The Garrett TFE731 (now Honeywell TFE731) is a family of geared turbofan engines commonly used on business jet aircraft. Garrett AiResearch originally designed and built the engine, which due to mergers was later produced by AlliedSignal and now Honeywell Aerospace. Since the engine was introduced in 1972, over 11,000 engines have been built, flying over 100 million flight-hours. Development The TFE731 was based on the core of the TSCP700, which was developed for use as the auxiliary power unit (APU) on the McDonnell Douglas DC-10. The design featured two important factors: low fuel consumption, and low noise profiles that met the newly established U.S. noise abatement regulations. The first test run of the TFE731 occurred in 1970 at Garrett's plant in Torrance, California. The first production model, the TFE731-2, began rolling off the assembly line in August, 1972, and was used on the Learjet 35/36 and Dassault Falcon 10, both of which entered production in 1973. The TF ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Learjet 25
The Learjet 25 is an American ten-seat (two crew and eight passengers), twin-engine, high-speed business jet aircraft manufactured by Learjet. It is a stretched version of the Learjet 24. Development The first Model 25 flew on August 12, 1966, and the first delivery was in November 1967. The Learjet 25 is similar to the Model 24 but is longer, allowing for three additional passengers. In 1970 the Learjet 25B was produced along with the Learjet 25C in the same year. Type development continued with the Models 25D and 25G, which included more advanced CJ610-8A engines and a ceiling increase to . By 2018, 1970s Learjet 25s were sold for under $200,000.

Learjet 24
The Learjet 24 is an American six-to-eight-seat (two crew and four to six passengers) twin-engine, high-speed business jet, which was manufactured by Learjet as the successor to the Learjet 23. History The Learjet 24 was designed as an improved version of the Learjet 23, which was limited to gross weight. Engineers designed the model 24 to accept up to the full gross weight permitted by Federal Aviation Regulations#Part 25, FAR-25 standards. Other improvements introduced in the Learjet 24 included: * increased cabin pressurization, to allow a higher operating altitude * the addition of one extra window on the right side of the cabin * more powerful engines * a new windshield * auxiliary fuel in wing tip tanks * a fire-extinguishing system for the engines With these changes, the LJ24 became the first business jet to be certified under FAR-25. The first flight of a Learjet 24 took place on January 24, 1966. From May 23 to 26, 1966, a Learjet 24 flew around the world in 50 h ...
