Official records versus unofficial. The Lockheed SR-71 Blackbird holds the official Air Speed Record for a crewed airbreathing jet engine aircraft with a speed of 3,530 km/h (2,190 mph). The record was set on 28 July 1976 by Eldon W. Joersz and George T. Morgan Jr. near Beale Air Force Base, California, USA.
The SR-71 was the world's fastest and highest-flying air-breathing operational manned aircraft throughout its career and it still holds that record. On 28 July 1976, SR-71 serial number 61-7962, piloted by then Captain Robert Helt, broke the world record: an "absolute altitude record" of 85,069 feet (25,929 m).
After burnout, controllers were still able to maneuver the vehicle and manipulate the flight controls for several minutes; the aircraft, slowed by air resistance, fell into the ocean. With this flight the X-43A became the fastest free-flying air-breathing aircraft in the world. NASA flew a third version of the X-43A on November 16, 2004.
The X-15 was built by two manufacturers: North American Aviation was contracted for the airframe in November 1955, and Reaction Motors was contracted for building the engines in 1956. Like many X-series aircraft, the X-15 was designed to be carried aloft and drop launched from under the wing of a B-52 mother ship.
Tupolev Tu-95 MS. Previously, the Guinness Book of World Records listed the Soviet Tupolev Tu-95 and Tu-142 bombers as "the fastest propeller-driven aircraft in standard production form", with a maximum level speed of 925 km/h (575 mph; 499 kn) or Mach 0.82. [ 6 ] XF-84H "Thunderscreech". Even earlier, in 1997, the Guinness Book of World ...
HTV-2 (artist rendering), the fastest uncrewed aerial vehicle. North American X-15, the fastest piloted rocket-powered aircraft. SR-71 Blackbird, the fastest piloted air-breathing aircraft. Rare Bear, the fastest piston-engined aircraft. Musculair 2, the fastest human-powered aircraft.
The aircraft was the largest and fastest passenger plane at that time and also had the longest range, at 10,900 km (6,800 mi). It has held the official title of fastest propeller-driven aircraft since 1960. [2] [3] Due to its swept wing and powerplant design, the Tu-114 was able to travel at speeds typical of modern jetliners, 880 km/h (550 mph).
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 ...
