ATR 52
The ATR 52 was a project to develop a military transport aircraft and a 50-seat airliner to add to ATR's product range.Taylor 1993, p.917Lambert, Munson & Taylor 1992, p.708 The manufacturer pursued the project throughout the 1990s, but was never able to attract sufficient interest from customers to make the project viable. Over the course of the decade, the design shifted from being a stretched ATR 42Sedbon 1992, p.6 to a shortened ATR 72.Taylor, Lambert & Munson 1993, p.133 Design and development Like other members of the ATR family, the ATR 52 was to be a high-wing cantilever monoplane of conventional design with a T-tail. It was to be powered by two wing-mounted turboprop engines driving tractor-mounted propellers. The design featured retractable tricycle undercarriage, the main units of which retracted into sponsons on the fuselage sides. ATR announced the project in April 1992 and undertook a market survey among prospective customers. At the time, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

French Air Force
The French Air and Space Force (, , ) is the air force, air and space force of the French Armed Forces. Formed in 1909 as the ("Aeronautical Service"), a service arm of the French Army, it became an independent military branch in 1934 as the French Air Force (). On 10 September 2020, it assumed its current name, the French Air and Space Force, to reflect an "evolution of its mission" into the area of outer space. The number of aircraft in service with the French Air and Space Force varies depending on the source; the Ministry of Armed Forces (France), Ministry of Armed Forces gives a figure of 658 aircraft in 2014.

Aircraft With Retractable Tricycle Landing Gear
An aircraft ( aircraft) is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or the dynamic lift of an airfoil, or, in a few cases, direct downward thrust from its engines. Common examples of aircraft include airplanes, rotorcraft (including helicopters), airships (including blimps), gliders, paramotors, and hot air balloons. Part 1 (Definitions and Abbreviations) of Subchapter A of Chapter I of Title 14 of the U. S. Code of Federal Regulations states that aircraft "means a device that is used or intended to be used for flight in the air." The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called ''aeronautics.'' Crewed aircraft are flown by an onboard pilot, whereas unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
T-tail Aircraft
A T-tail is an empennage configuration in which the tailplane of an aircraft 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 lowe ...

High-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 wings. 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 an ...

Pratt & Whitney Canada PW127
The Pratt & Whitney Canada PW100 aircraft engine family is a series of turboprops manufactured by Pratt & Whitney Canada. Pratt & Whitney Canada dominates the turboprop market with 89% of the turboprop regional airliner installed base in 2016, leading GE Aviation and Allison Engine Company. Development The engine was first introduced as a technology demonstrator in 1977. The PW100 was first tested in March 1981, made its initial flight in February 1982 on a Vickers Viscount testbed aircraft, and then entered service in December 1984 on a Dash 8 regional aircraft for NorOntair. The PW150 engine was introduced on 24 April 1995, when Bombardier selected the engine for the launch of its de Havilland Dash 8-400 regional turboprop. The PW150 was a higher-power version of the PW100 series, with the low-pressure compressor changed from a single-stage centrifugal compressor to a three-stage axial compressor, and the turbine modified to have improved cooling.

Fokker 50
The Fokker 50 is a turboprop-powered airliner manufactured and supported by Dutch aircraft manufacturer Fokker. It was designed as an improved version of the successful Fokker F27 Friendship. The Fokker 60 is a stretched freighter version of the Fokker 50. The Fokker 50 was developed during the early 1980s following a decline in the sales of the company's earlier F27 Friendship. It was decided that the new airliner would be a derivative of its predecessor, sharing much of its airframe and design features, while incorporating new advances and several improvements, such as the adoption of Pratt & Whitney Canada PW127B turboprop engines, in order to produce a successor that had a 30 percent reduction in fuel consumption over the F27. The Fokker 50 performed its maiden flight on 28 December 1985, and entered revenue service during 1987. The Fokker 60 has been operated by the Royal Netherlands Air Force (RNLAF), ex-RNLAF aircraft are also in service with the Peruvian Naval Aviati ...
