After completing its initial test flights in 1959, the X-15 became the first winged aircraft to attain velocities of Mach 4, 5, and 6.

Highlighted in this image is an ejection seat label on the North American x-15.The North American X-15 rocket-powered research aircraft bridged the gap between manned flight within the atmosphere and manned flight beyond the atmosphere into space. See more ideas about Experimental aircraft, Fighter jets, Aircraft. The X-15 was based on a concept study from Walter Dornberger for the National Advisory Committee for Aeronautics (NACA) for a hypersonic research aircraft. After completing its initial test flights in 1959, the X-15 became the first winged aircraft to attain velocities of Mach 4, 5, and 6. Sorry, there was a problem. Learn how aviation and spaceflight transformed the world. Because the X-15 also had to be controlled in an environment where there was too little air for aerodynamic The X-15 type with multiple control sticks for the pilot included a traditional rudder and stick, and another joystick on the left which sent commands to the reaction control system.The second setup used the MH-96 flight control system which allowed one joystick in place of three and simplified pilot input.Among the many controls were the rocket engine throttle and a control for jettisoning the ventral tail fin.The X-15 had an ejection seat that allowed ejection at speeds up to Mach 4 and/or 120,000 feet (X-15 attached to its B-52 mother ship with a T-38 flying nearbyThe X-15 had a thick wedge tail to enable it to fly in a steady manner at hypersonic speeds.Members of the X-15 flight crew, left to right: Engle, Rushworth, McKay, Knight, Thompson, and Dana.Altitudes attained by X-15 aircraft do not match those of Three X-15s were built, flying 199 test flights, the last on 24 October 1968.

Republic. Highlighted in this image are the rocket engine of the North American X-15.The North American X-15 rocket-powered research aircraft bridged the gap between manned flight within the atmosphere and manned flight beyond the atmosphere into space. The North American X-15 was the culmination of the rocket powered research aircraft that peppered the 1940s and 1950s beginning with the famous Bell X-1. California. After completing its initial test flights in 1959, the X-15 became the first winged aircraft to attain velocities of Mach 4, 5, and 6.

Without the main engine on, the X-15's instruments and control surfaces remained functional, but the plane could not maintain altitude. After completing its initial test flights in 1959, the X-15 became the first winged aircraft to attain velocities of Mach 4, 5, and 6.

After completing its initial test flights in 1959, the X-15 became the first winged aircraft to attain velocities of Mach 4, 5, and 6. Because the X-15 also had to be controlled in a region where there was too little air for aerodynamic surfaces, it had a The X-15 type with multiple control sticks for the pilot, included a traditional rudder and stick, and another joystick on the left which gave commands to the reaction control system.The other setup used the MH-96 flight control system which allowed one joystick in place of three and simplified pilot inputs.Among the many other controls, were the rocket engine throttle and a control for ejecting the bottom tail fin.The X-15 had an ejection seat that allowed ejection at speeds up to Mach 4 and/or 120,000 feet (37 km) altitude, although it was not used during the program.The X-15 had a thick wedge tail for stability at hypersonic speeds.Additionally, stability at hypersonic speeds was aided by side panels that could extend out from the tail to further increase area, and these panels doubled as air-brakes.Altitudes attained by X-15 aircraft do not match those of Three X-15s were built, flying 199 test flights, the last on 24 October 1968.
Looking at it another way, Mach 6 is about one mile per second, and flight above 264,000 ft. qualifies an Air Force pilot for astronaut wings.


At one point, NASA scientists planned to test a hydrogen-fueled supersonic combustion ramjet engine mounted on the X-15s lower vertical fin.
