It has a lot of interesting information about current and past Blackbird activities at NASA Ames-Dryden... --------------------------------------------------------------------- NASA Facts Ames Research Center Dryden Flight Research Facility SR-71 "The Blackbird" Three SR-71 aircraft have been loaned to NASA by the U.S. Air Force as testbeds for high speed, high altitude aeronautical research. The aircraft, two SR-71A's and the only SR-71B pilot trainer aircraft in operation, are based at NASA's Dryden Flight Research Facility, Edwards, Calif. Developed for the U.S. Air Force as a reconnaissance aircraft more than 27 years ago, SR-71's are still the world's fastest and highest-flying production aircraft. The aircraft can fly more than 2200 mph (Mach 3+ or more than three times the speed of sound) and at altitudes of over 85,000 feet. This operating environment makes the aircraft excellent platforms to carry out research and experiments in a variety of areas -- aerodynamics, propulsion, structures, thermal protection materials, high-speed and high-temperature instrumentation, and sonic boom characterization. Data from the SR-71 high speed research program will be used to aid designers of future supersonic/hypersonic aircraft and propulsion systems. Beneficiaries of this data include a future high speed civil transport and the National Aero-Space Plane (NASP) program. Program Management The SR-71 program at Dryden is part of NASA's overall high speed aeronautical research program, and is expected to involve many NASA research centers, and other government agencies. Project manager at Dryden is David P. Lux NASA Flight Crews Each NASA crew consists of a pilot and a flight engineer. Currently assigned as SR-71 project pilots at Dryden are Stephen D. Ishmael and Roger E. Smith. Flight engineers are Robert E. Meyer and Marta Bohn- Meyer. The Meyers are the first husband-wife team of aeronautical engineers on flight status at Dryden. Both pilot-engineer crews have trained for many hours in the SR-71 flight simulator at Dryden to become thoroughly acquainted with aircraft systems and operational procedures. The simulator is the same unit used by Air Force personnel at Beale AFB, Calif., before the SR-71s were retired from military service in 1990. As military aircraft, SR-71's had a crew of two -- a pilot and a reconnaissance systems officer. Mach 3 at Dryden Dryden has a decade of experience at sustained speeds above Mach 3. Two YF-12 aircraft were flown at the facility between December 1969 and November 1979 in a joint NASA/Air Force program to learn more about the capabilities and limitations of high speed, high altitude flight. The YF-12s were prototypes of a planned interceptor aircraft based on a design that later evolved into the SR-71 reconnaissance aircraft. Research information from the YF-12 program was used to validate analytical theories and wind tunnel test techniques to help improve the design and performance of future military and civil aircraft. The then-developing American supersonic transport project would have benefited greatly from YF-12 research data. The aircraft were a YF-12A (serial 935) and a YF-12C (serial 937). They logged a combined total of 242 flights during the program. A third aircraft, a YF-12A (serial 936), was flown by Air Force crews early in the program. It was lost because of an inflight fire in June 1971. The crew was not hurt. The YF-12s were used for a wide range of experiments and research. Among the areas investigated were aerodynamic loads, aerodynamic drag and skin friction, heat transfer, thermal stresses, airframe and propulsion system interactions, inlet control systems, high altitude turbulence, boundary layer flow, landing gear dynamics, measurement of engine effluents for pollution studies, noise measurements, and evaluation of a maintenance monitoring and recording system. On many YF-12 flights medical researchers obtained information on the physiological and biomedical aspects of crews flying at sustained high speeds. From February 1972 until July 1973, the YF-12A was used for heat loads testing in Dryden's High Temperature Loads Laboratory (now the Thermostructures Research Facility). The data helped improve theoretical prediction methods and computer models of that era dealing with structural loads, materials, and heat distribution at up to 800 degrees (F), the same surface temperatures reached during sustained speeds of Mach 3. SR-71 Specifications & Performance The SR-71 is a delta-wing aircraft designed and built by Lockheed. They are powered by two Pratt and Whitney J-58 axial-flow turbojets with afterburners, each producing 32,500 pounds of thrust. Speed of the aircraft is announced at Mach 3.2 -- more than 2000 mph. They have a range of more than 2000 miles and fly at altitudes of over 85,000 ft. As research platforms, the aircraft can cruise at Mach 3 for more than one hour. For thermal experiments, this can produce heat soak temperatures of more than 600 degrees (F). The aircraft are 107.4 feet long, have a wing span of 55.6 feet, and are 18.5 feet high (ground to top of rudders when parked). Gross takeoff weight is about 140,000 pounds, including a fuel weight of 80,000 pounds. The airframes are built almost entirely of titanium and titanium alloys to withstand heat generated by sustained Mach 3 flight. Aerodynamic control surfaces consist of all-moving vertical tail surfaces above each engine nacelle, ailerons on the outer wings, and elevators on the trailing edges between the engine exhaust nozzles. The three SR-71's at Dryden have been assigned the following NASA tail numbers: NASA 831 (B model), military serial 64-17956, manufactured in September 1965; NASA 832 (A model), military serial 64-17971, manufactured in October 1966; NASA 844 (A model), military serial 64-17980, manufactured in July 1967. Development History The SR-71 was designed by a team of Lockheed personnel led by Clarence "Kelly" Johnson, at that time vice president of the company's Advanced Development Projects. The Advanced Development Projects is commonly referred to as the "Skunk Works". The basic design of the SR-71 and YF-12 aircraft originated in secrecy in the late 1950s with the aircraft designation of A-11. Its existence was publicly announced by President Lyndon Johnson on Feb. 29, 1964, when he announced that an A-11 had flown at sustained speeds of over 2000 mph during tests at Edwards, Calif. Development of the SR-71's from the A-11 design, as strategic reconnaissance aircraft, began in February 1963. First flights of an SR-71 was on Dec. 22, 1964. The YF-12's were experimental long-range interceptor versions of the same airframe and were first displayed publicly at Edwards on Sept. 30, 1964. -nasa- December 1991
