The North American X-15 is a hypersonic rocket-powered aircraft which was operated by the United States Air Force and the National Aeronautics and Space Administration (NASA) as part of the X-plane series of experimental aircraft.

2014年2月28日 · The X-15 was a follow-on research aircraft to the early X-planes, which had explored the flight regime from just below the speed of sound (Mach 1) to Mach 3.2. In 1952, the NACA had begun preliminary research into space flight and associated problems.

On Sept. 17, at the controls of X-15-2, Crossfield completed the first powered flight of an X-15. Firing all eight of the XLR-11 engines for 224 seconds, he reached a speed of Mach 2.11, or 1,393 miles per hour, and an altitude of 52,341 feet.

2023年10月13日 · On Oct. 15, 1958, the first X-15 hypersonic rocket-powered aircraft rolled out of its factory. A joint project among NASA, the U.S. Air Force, and the U.S. Navy, the X-15 greatly expanded our knowledge of flight at speeds exceeding Mach 6 and altitudes above 250,000 feet.

The X-15 and other X-planes are more than a historical legacy for NASA. The program is the core of NASA’s New Aviation Horizons, an array of new experimental aircraft that will carry on the legacy of demonstrating advanced technologies to push back the frontiers of aviation.

The X-15 is a famous and significant part of aviation history. Its purpose was to fly high and fast, testing the machine and subjecting pilots to conditions that future astronauts would face.

From 1959 through 1968 a decade-long research program employed the North American Aviation X-15 to explore hypersonic flight and technologies needed for space flight.
