Bombardier Challenger 604
The Bombardier Challenger 600 series is a family of business jets developed by Canadair after a Bill Lear concept, and then produced from 1986 by its new owner, Bombardier Aerospace. At the end of 1975, Canadair began funding the development of LearStar 600, and then bought the design for a wide-cabin business jet in April 1976. On 29 October, the programme was launched, backed by the Canadian federal government, and designed to comply with new FAR part 25 standards. In March 1977, it was renamed the Challenger 600 after Bill Lear was phased out, and the original conventional tail was changed for a T-tail among other developments. The first prototype was rolled out on 25 May 1978, and performed its maiden flight on 8 November. The flight test program saw a deadly crash on 3 April 1980, but Transport Canada approved the CL-600 type certification on 10 August 1980. In 1986, Canadair was close to bankruptcy and was bought by Bombardier. The jet was later stretched into the B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dassault Falcon 50
The Dassault Falcon 50 is a French super-midsize, long-range business jet, featuring a trijet layout with an S-duct air intake for the central engine. It has the same fuselage cross-section and similar capacity as the earlier twin-engined Falcon 20, but was a new design that is area ruled and includes a more advanced wing design.Taylor 1988, p.75. Design and development The first prototype flew on 7 November 1976, with French airworthiness certification on 27 February 1979, followed by U.S. Federal Aviation Administration certification on 7 March 1979. Dassault developed a maritime surveillance and environmental protection version as the Gardian 50. The Falcon 50 was later updated as the Falcon 50EX, the first of which flew in 1996, and the last of which was delivered in 2008. The Falcon 50EX features improved engines and other enhancements to give further range improvements to an already long-range jet. The Falcon 50EX designation applies to serial numbers 253–352, which ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lockheed Jetstar
The Lockheed JetStar (company designations L-329 and L-1329; designated C-140 in US military service) is a business jet produced from the early 1960s to the 1970s. The JetStar was the first dedicated private jet to enter service, as well as the only such airplane built by Lockheed. It was also one of the largest aircraft in the class for many years, seating ten plus two crew. It is distinguishable from other small jets by its four engines, mounted on the rear of the fuselage, and the "slipper"-style fuel tanks fixed to the wings. Development The JetStar originated as a private project within Lockheed, with an eye to winning a United States Air Force (USAF) requirement that was later dropped due to budget cuts. Lockheed decided to continue the project on its own for the business market. The first two prototypes were equipped with two Bristol Siddeley Orpheus engines, the first of these flying on 4 September 1957. The second of these was also equipped with the wing-mounted "s ...

Geared Turbofan
The geared turbofan is a type of turbofan aircraft engine with a planetary gearbox between the low pressure compressor / turbine and the fan, enabling each to spin at its optimum speed. The benefit of the design is lower fuel consumption and much quieter operation. The drawback is that it increases weight and adds complexity. Technology In a conventional turbofan, a single shaft (the "low-pressure" or LP shaft) connects the fan, the low-pressure compressor and the low-pressure turbine (a second concentric shaft connects the high-pressure compressor and high-pressure turbine). In this configuration, the maximum tip speed for the larger radius fan limits the rotational speed for the LP shaft and thus the LP compressor and turbine. At high bypass ratios (and thus also high radius ratios) the rotational speed of the LP turbine and compressor must be relatively low, which means extra compressor and turbine stages are required to keep the average stage loadings and, therefore, overa ...

Garrett 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] |
Winglets
Wingtip devices are intended to improve the efficiency of fixed-wing aircraft by reducing drag. Although there are several types of wing tip devices which function in different manners, their intended effect is always to reduce an aircraft's drag. Such devices reduce drag by increasing the height of the lifting system, without greatly increasing the wingspan. Extending the span would reduce lift-induced drag, but would increase parasitic drag and would require boosting the strength and weight of the wing. At some point, there is no net benefit from further increased span. There may also be operational considerations that limit the allowable wingspan (e.g. available width at airport gates). Physics When a conventional wing generates lift, it also experiences lift-induced drag. Higher pressure air under the wing flows to the lower pressure surface on top at the wingtip, which results in a vortex caused by the forward motion of the aircraft. Trefftz-plane theory shows t ...
