52 mothership with its rocket engine ignited The white patches near the middle of the ship are frost from the liquid oxygen used in the propulsion system although very cold liquid nitrogen was also used to cool the payload bay cockpit windshields and nose The X 15 was a rocket powered aircraft 50 ft long with a wingspan of 22 ft It was a missile shaped vehicle with an unusual wedge shaped vertical tail thin stubby wings and unique fairings that extended along the side of the fuselage The X 15 weighed about 14 000 lb empty and approximately 34 000 lb at launch The XLR 99 rocket engine manufactured by Thiokol Chemical Corp was pilot controlled and was capable of developing 57 000 lb of rated thrust actual thrust reportedly climbed to 60 000 lb North American Aviation built three X 15 aircraft for the program lt p gt The X 15 research aircraft was developed to provide in flight information and data on aerodynamics structures flight controls and the physiological aspects of high speed high altitude flight A follow on program used the aircraft as a testbed to carry various scientific experiments beyond the Earth s atmosphere on a repeated basis lt p gt For flight in the dense air of the usable atmosphere the X 15 used conventional aerodynamic controls such as rudder surfaces on the vertical stabilizers to control yaw and canted horizontal surfaces on the tail to control pitch when moving in synchronization or roll when moved differentially lt p gt For flight in the thin air outside of the appreciable Earth s atmosphere the X 15 used a reaction control system Hydrogen peroxide thrust rockets located on the nose of the aircraft provided pitch and yaw control Those on the wings provided roll control lt p gt Because of the large fuel consumption the X 15 was air launched from a B 52 aircraft at 45 000 ft and a speed of about 500 mph Depending on the mission the rocket engine provided thrust for the first 80 to 120 sec of flight The remainder of the normal 10 to 11 min flight was powerless and ended with a 200 mph glide landing lt p gt Generally one of two types of X 15 flight profiles was used a high altitude flight plan that called for the pilot to maintain a steep rate of climb or a speed profile that called for the pilot to push over and maintain a level altitude lt p gt The X 15 was flown over a period of nearly 10 years June 1959 to Oct 1968 and set the world s unofficial speed and altitude records of 4 520 mph Mach 6 7 and 354 200 ft over 67 mi in a program to investigate all aspects of piloted hypersonic flight Information gained from the highly successful X 15 program contributed to the development of the Mercury Gemini and Apollo manned spaceflight programs and also the Space Shuttle program lt p gt The X 15s made a total of 199 flights and were manufactured by North American Aviation lt p gt X 15 1 serial number 56 6670 is now located at the National Air and Space Museum Washington DC lt p gt North American X 15A 2 serial number 56 6671 is at the United States Air Force Museum Wright Patterson AFB Ohio The X 15 3 serial number 56 6672 crashed on 15 November 1967 resulting in the death of Maj Michael J Adams ත රස ව භ
