The NASA X-43 was an experimental unmanned hypersonic aircraft with multiple planned scale variations meant to test various aspects of hypersonic flight.It was part of the X-plane series and specifically of NASA's Hyper-X program developed in the late 1990s. [1] It set several airspeed records for jet aircraft.The X-43 is the fastest jet-powered aircraft on …

2024年1月5日 · The highest speed attained by a rocket-powered airplane, NASA’s X-15 aircraft, was Mach 6.7. The fastest air-breathing, crewed vehicle, the SR-71 achieved slightly over Mach 3. The X-43A more than doubled the top speed of the jet-powered SR-71. 2001 Flight and Investigation. The first flight attempt of the X-43A was in June of 2001.

NASA X-43. NASA's X-43A or Hyper-X air vehicle achieved a record-breaking speed of close to Mach 10 (12,000km/hr or 7,000mph) in a test flight in November 2004, which was the culmination of a three-flight test program. ... A B-52 aircraft was used to carry the X-43A on the starboard wing pylon to an altitude over 40,000ft (12,000m). The B-52 ...

2016年3月7日 · After being launched by Dryden’s venerable B-52B mothership off the coast of Southern California, a modified first-stage Pegasus booster rocketed the X-43A to 95,000 feet before the X-43A separated and flew under its own scramjet power at an airspeed of Mach 6.8, or about 5,000 mph, for about 11 seconds.

2024年8月24日 · The first two X-43 test vehicles were produced to fly at Mach 7, which was faster than any air-breathing aircraft had ever flown; while a third X-43 was even able to achieve a speed of nearly Mach ...

X-43A Mishap Investigation Board (MIB) was immediately convened following the accident on June 5, 2001 and ended 9 months later. • “ The X-43A HXLV failed because the vehicle control system design was deficient for the trajectory flown due to inaccurate analytical models which overestimated the system margins ”-- Root Cause MIB Report ...

The X-43 was an unmanned experimental hypersonic aircraft with multiple planned scale variations meant to test various aspects of hypersonic flight. It was part of the X-plane series and specifically of NASA's Hyper-X program. It set several airspeed records for jet-propelled aircraft. The X-43 is the fastest aircraft on record at approximately Mach 9.6 (Template:Convert/sround mph) (11,000 km ...

The other X-43 programmes were also suspended shortly after the X-43C was cancelled. Top. The Vehicles. The X-43As were small, unmanned lifting body/wave-riding vehicles only 12 ft 4 in (3.7 metres) long and weighing a mere 2 800 pounds (1 300 kg).
