The North American X-15 is a hypersonic rocket-powered aircraft 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 data used ...
28 Φεβ 2014 · Because of the large fuel consumption of its rocket engine, the X-15 was air launched from a B-52 aircraft at about 45,000 feet and speeds upward of 500 mph. Depending on the mission, the rocket engine provided thrust for the first 80 to 120 seconds of flight.

The X-15 was air launched from a B-52 aircraft at 45,000 feet and at a speed of about 500 mph. After dropping from the B-52, the rocket engine provided thrust for the first 80 to 120 seconds of flight.
13 Οκτ 2023 · 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.
3 Οκτ 2021 · On October 3, 1967, the X-15 rocket plane achieved a world record speed of Mach 6.7, which is 7,274 km/h (4,520 mph or over a mile per second) with U.S. Air Force pilot Pete Knight. As by today, this record still holds for the highest speed ever reached by a manned, powered aircraft.
18 Μαρ 2014 · Mounted under the wing of a B-52 jet bomber, on that day the X-15 and Crossfield were carried to an altitude of 11,445 meters (37,550 feet), and then released. This first flight was a gliding flight; the rocket powered flights were to come later. Nevertheless, the X-15 reached a speed of Mach 0.79 on its decent to the desert floor below.
