The Republic XF-84H "Thunderscreech" is an American experimental turboprop aircraft derived from the F-84F Thunderstreak.Powered by a turbine engine that was mated to a supersonic propeller, the XF-84H had the potential of setting the unofficial air speed record for propeller-driven aircraft, but was unable to overcome aerodynamic deficiencies and engine reliability problems, resulting in the ...
A number of aircraft have been claimed to be the fastest propeller-driven aircraft. This article presents the current record holders for several sub-classes of propeller-driven aircraft that hold recognized, documented speed records in level flight. Fédération Aéronautique Internationale (FAI) records are the basis for this article. [1]
The first production Cheyenne III flew for the first time on May 18, 1979, and FAA certification was granted in early 1980. Compared with the Cheyenne II, the PA-42-720 was about 1 m (3 ft) longer, was powered by 537 kW (720-shp) PT6A-41 turboprops and introduced a T-tail, the most obvious external difference between the PA-31T and PA-42, as ...
Production period column shows overall production date span of all types included in "Numbers produced" column, disregarding production hiatuses and changes in manufacturer, while including close variants and licensed production. a pale-green background indicates aircraft still in production.
To “break the sound barrier” means to fly faster than the speed of sound, with Mach numbers greater than 1. The Mach number is an important ratio: as a plane flies, it disturbs the air in ...
The fractional aircraft operator Avantair was Piaggio's largest client, with a fleet of 57 Avanti aircraft, [28] before they went bankrupt and the fleet was liquidated. [77] [78] In May 2017, 220 aircraft were in operation around the world, [79] with 89 being first-generation Avanti, 126 second-generation Avanti II and 6 Avanti EVO models. [80]
While the program may not have lived up to its full potential, the XB-70’s legacy still stands, Landis says: “All large, high-speed aircraft designs benefit from the work done by the XB-70.
The Dornier 328 is a turboprop-powered commuter airliner.Initially produced by Dornier Luftfahrt GmbH, the firm was acquired in 1996 by Fairchild Aircraft.The resulting firm, named Fairchild-Dornier, manufactured the 328 family in Oberpfaffenhofen, Germany, conducted sales from San Antonio, Texas, United States, and supported the product line from both locations.
