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. The X-15 set speed and altitude records in the 1960s, crossing the edge of outer space and returning with valuable ...

x-15 高超音速研究项目是由 nasa 牵头，联合美国空军、海军和北美航空公司共同进行的。x-15的速度和高度记录在20世纪60年代出现，到达外层空间的边缘，并返回与在飞机和航天器设计中使用的有价值的数据。

2014年2月28日 · In the joint X-15 hypersonic research program that NASA conducted with the U.S. Air Force, the Navy, and North American Aviation Inc., the aircraft flew during a period of nearly 10 years and set the world’s unofficial speed and altitude records of 4,520 mph (Mach 6.7) and 354,200 feet in a program to investigate all aspects of piloted ...

Three X-15 spaceplanes performed 199 free flights. The flights of the North American X-15, an experimental American spaceplane built by North American Aviation and operated by the United States Air Force and NASA, were conducted from 1959 to 1968.

2024年9月17日 · The X-15 hypersonic rocket-powered aircraft, built by North American Aviation (NAA), greatly expanded our knowledge of flight at speeds exceeding Mach 6 and Explore Search

2025年2月2日 · The X-15 was the first aircraft to cross the boundaries of outer space. It was also the first airplane to reach hypersonic speed. Neil A. Armstrong, a NASA pilot and the first person to moon, has been documented at the contracted flight test program. The B-52 carrying the X-15 for a research flight on 13 April 1960 on Air Force Maj.

This joint program by NASA, the Air Force, the Navy, and North American operated the most remarkable of all the rocket research aircraft. Composed of an internal structure of titanium and a skin surface of a chrome-nickel alloy known as Inconel X, the X-15 had its first, unpowered glide flight on June 8, 1959, while the first powered flight ...

Ultimately, the X-15 flew 199 times, and on Oct. 3, 1967, U.S. Air Force pilot Pete Knight set a speed record of Mach 6.7. But as important as the records was everything that NACA, and later NASA, researchers learned about operating craft at high speeds and altitudes.

2024年3月4日 · The North American X-15 rocket plane was perhaps the most important of the USAF/USN X-series of experimental aircraft. Although not as famous as the Bell X-1, the X-15 set numerous speed and altitude records in the early 1960s, reaching the edge of space and bringing back valuable data that was used in the design of later aircraft and spacecraft.

The Shenyang J-15 (Chinese: 歼-15), also known as Flying Shark (Chinese: 飞鲨; pinyin: Fēishā; NATO reporting name: Flanker-X2, [3]) is a Chinese all-weather, twin-engine, carrier-based 4.5 generation [4] multirole fighter aircraft developed by the Shenyang Aircraft Corporation (SAC) and the 601 Institute, specifically for the People's Liberation Army Naval Air Force (PLANAF) to …
