Cessna 526 CitationJet
The Cessna 526 CitationJet was a twinjet trainer candidate for the United States Joint Primary Aircraft Training System proposed by Cessna. It was a twin-engined, tandem seat aircraft, based on the Cessna CitationJet executive aircraft. However, it was unsuccessful, with only two prototypes built. Design and development The United States military issued a request for proposal for a trainer to be used by the United States Air Force and United States Navy. Cessna responded with the 526, based on its Cessna CitationJet, 525 CitationJet civilian business jet. The 526 and 525 shared 75% commonality including the wings, engines and landing gear. The electrical- hydraulic- and fuel systems were also common to the two types. The 526 had a redesigned fuselage featuring a tandem two-seat cockpit with zero-zero ejection seats; and a new empennage with a low-mounted tailplane instead of the 525's T-tail. The prototype first flew on 20 December 1993 and was followed by a second prototype with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Low-wing Aircraft
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplanes, which have multiple planes. A monoplane has inherently the highest efficiency and lowest drag of any wing configuration and is the simplest to build. However, during the early years of flight, these advantages were offset by its greater weight and lower manoeuvrability, making it relatively rare until the 1930s. Since then, the monoplane has been the most common form for a fixed-wing aircraft. Characteristics Support and weight The inherent efficiency of the monoplane is best achieved in the cantilever wing, which carries all structural forces internally. However, to fly at practical speeds the wing must be made thin, which requires a heavy structure to make it strong and stiff enough. External bracing can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, the weight reduction allows it to fly slower ...

Cessna Aircraft
Cessna () is an American brand of general aviation aircraft owned by Textron Aviation since 2014, headquartered in Wichita, Kansas. Originally, it was a brand of the Cessna Aircraft Company, an American general aviation aircraft manufacturing corporation also headquartered in Wichita. The company produced small, piston-powered aircraft, as well as business jets. For much of the mid-to-late 20th century, Cessna was one of the highest-volume and most diverse producers of general aviation aircraft in the world. It was founded in 1927 by Clyde Cessna and Victor Roos and was purchased by General Dynamics in 1985, then by Textron, Inc. in 1992. In March 2014, when Textron purchased the Beechcraft and Hawker Aircraft corporations, Cessna ceased operations as a subsidiary company and joined the others as one of the three distinct brands produced by Textron Aviation. Throughout its history, and especially in the years following World War II, Cessna became best-known for producing high- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rockwell Ranger 2000
The Rockwell Ranger 2000 was a jet trainer candidate for the United States Joint Primary Aircraft Training System proposed by Rockwell International with assistance from Rhein-Flugzeugbau GmbH (RFB) in Germany. Design and development The United States military issued a Request for proposal for a jet trainer for use by the United States Air Force and United States Navy. Rockwell responded with the Ranger 2000 two-seat, single engined cantilever monoplane. The design was based on the work of RFB, in particular the RFB Fantrainer and the prototypes were built in Germany. The Ranger 2000 was powered by a Pratt & Whitney Canada JT15D-5C turbofan mounted in the rear fuselage and fed by two air intakes above the wing roots. It used retractable tricycle landing gear, the wing was straight and low-mounted, and the crew of two sat in tandem with the rear instructor raised to maintain visibility. Both crew had a Stencel zero-zero ejection seat. The aircraft first flew on 15 January ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Williams FJ44
The Williams FJ44 is a family of small, two-spool, turbofan engines produced by Williams International for the light business jet market. Until the recent boom in the very light jet market, the FJ44 was one of the smallest turbofans available for civilian applications. Although basically a Williams design, Rolls-Royce was brought into the project at an early stage to design, develop, and manufacture an air-cooled high-pressure (HP) turbine for the engine. The FJ44 first flew on July 12, 1988 on the Scaled Composites/Beechcraft Triumph aircraft. The Williams FJ33 is a newer, smaller engine based on the basic FJ44 design. Development Production started in 1992 with the thrust FJ44-1A. The FJ44-1C is derated to . The uprated to FJ44-2A was introduced in 1997. The thrust FJ44-3A was introduced in 2004. In 2005, a new low end version, the FJ44-1AP, was introduced, with a takeoff thrust. Released in 2007 was the new thrust FJ44-4. In 2010 this engine was in use on the Cessna ...

Pilatus PC-9
The Pilatus PC-9 is a single-engine, low-wing tandem-seat turboprop training aircraft manufactured by Pilatus Aircraft of Switzerland. Designed as a more powerful evolution of the Pilatus PC-7, the PC-9's first flight was made in May 1984 after which certification was achieved in September 1985. After this, the first production orders for the type were received from the Royal Saudi Air Force, with deliveries commencing in 1985. Since then, more than 250 airframes have been produced across five different variants and the type is employed by a number of military and civilian operators around the world, including the Swiss Air Force, the Croatian Air Force, and the Royal Thai Air Force. Design and development The PC-9 is a more powerful evolution of the PC-7. It retains the overall layout of its predecessor, but it has very little structural commonality with it. Amongst other improvements, the PC-9 features a larger cockpit with stepped ejection seats and also has a ventral airb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
T-tail
A T-tail is an empennage configuration in which the tailplane is mounted to the top of the fin. The arrangement looks like the capital letter T, hence the name. The T-tail differs from the standard configuration in which the tailplane is mounted to the fuselage at the base of the fin. Advantages T-tails were common in early jet aircraft. Designers were worried that an engine failure would otherwise damage the horizontal tail. The T-tail is very common on aircraft with engines mounted in nacelles on a high-winged aircraft or on aircraft with the engines mounted on the rear of the fuselage, as it keeps the tail clear of the jet exhaust. Rear-mounting the engines keeps the wings clean and improves short-field performance. This was necessary in early jet aircraft with less powerful engines. T-tail aircraft can have better short-field performance, such as on the Avro RJ-85. The disturbed airflow over a lower stabilizer can make control more difficult at lower speeds. Dur ...
