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.

2024年1月5日 · At nearly 5,000 mph, the March flight easily broke the previous world speed record for a jet-powered (air breathing) vehicle. The X-43A research vehicle was boosted to 95,000 feet for a brief preprogrammed engine burn at …

2024年3月8日 · The X-43, an experimental aircraft, holds the distinction of being not only the fastest fighter jet but the fastest aircraft ever built period, having achieved a top speed of Mach 9.6. As part of a $230 million Hyper-X program, the National Aeronautics and Space Administration (NASA) developed the X-43 to explore hypersonic flight.

美国国家航空航天局研发的X-43是用来研究 超燃冲压发动机 的无人驾驶试验机。 X-43长3.66 m，质量为1 361 kg，仅携带9.9 kg的氢燃料。 X-43高超声速飞行器吸入空气，所以不需要携带氧化剂。 B-52载机和1枚空中发射的火箭将X-43高超声速飞行器带入高空，并推进其到飞行所需的速度。 美国共研制了3架X-43高超声速飞行器，并进行了3次测试，耗资2．3亿美元。 [1] 美国宇航局事前透露，X-43将在5月底进行第一次无人驾驶遥控试飞。 随着首次试飞时期的临近，X-43A …

The X-43A easily broke the record for the fastest free-flying air breathing aircraft in the world. A ramjet-powered missile that flew at a little over Mach 5 in July 2001 held the previous record in the same category.

This paper provides an overview of the final flight of the NASA X-43A project. The project consisted of three flights, two planned for Mach 7 and one for Mach 10. The third and final flight, November 16, 2004, was the first Mach 10 flight demonstration of an airframe-integrated, scramjet-powered, hypersonic vehicle.

NASA's X-43A scramjet-powered research vehicle broke the air speed record November 16 and showed that an "air-breathing" engine can fly at nearly 10 times the speed of sound.

X-43A ballasted for flight weight and CG location. Purpose: demonstrate that mechanical systems function as expected, test adapter cameras, and validate separation simulation.

The X-43 is powered by a scramjet (Supersonic Combustion Ramjet) engine. Unlike traditional jet engines that compress air and mix it with fuel at subsonic speeds, a scramjet operates with air intake at supersonic speeds, maintaining its velocity throughout the combustion process.
