Details, quoting Smithsonian National Air and Space Museum | 63eae523dd568a0984044097af9e1452: No reconnaissance aircraft in history has operated globally in more hostile airspace or with such impunity than the SR-71 fastest jet in the world. The Blackbird's performance and operational achievements placed on top of the technological advances of aviation during the War Fría.Esta Blackbird accrued about 2,800 hours of flight time during 24 years of active duty in the U.S. Air Force. On its last flight, March 6, 1990, Lt. Col. Ed Yielding and Lt. Col. Joseph Vida set a speed record by flying from Los Angeles to Washington, DC, in 1 hour, 4 minutes and 20 seconds, averaging 3,418 kilometers (2,124 miles) per hour. At the conclusion of the flight, which landed at Washington-Dulles International Airport and turned the airplane to the Smithsonian. Transferred from the Air Force of the United States.

Long Description: No plane recognition in history has operated in more hostile airspace or with such impunity that the SR-71 Blackbird. It is the fastest aircraft propelled by air-breathing engines. The Blackbird's performance and operational achievements placed on top of the technological advances of aviation during the Cold War. The airplane was conceived when tensions with communist Eastern Europe reached levels approaching a full-blown crisis in the mid-1950s. U.S. military commanders desperately needed accurate assessments of Soviet military deployments around the world, particularly near the Iron Curtain. Subsonic Aircraft Corporation Lockheed U-2 (see NASM collection) reconnaissance aircraft was an able platform but the U.S. Air Force recognized that this relatively slow aircraft was already vulnerable to Soviet interceptors. They also understood that the rapid development of systems-air missiles could put U-2 pilots at grave risk. The danger proved reality when a U-2 was shot down by a surface-to-air missile over the Soviet Union in 1960.Primera Lockheed proposal for a new high speed, high altitude, reconnaissance aircraft, to be capable of preventing and missiles interceptors, centered on a design propelled by liquid hydrogen. This proved to be impracticable because of a substantial fuel consumption. Lockheed then reconfigured the design for conventional fuels. This was possible and the Central Intelligence Agency (CIA), already flying the Lockheed U-2, issued a production contract for an aircraft designated the A-12. The division of Lockheed clandestine 'Skunk Works "(directed by the gifted design engineer Clarence L." Kelly "Johnson) designed the A-12 to cruise at Mach 3.2 and fly well above 18,288 m (60,000 ft .) To meet these demanding requirements, Lockheed engineers overcame many daunting technical challenges. Flying more than three times the speed of sound generates 316 ° C (600 ° F) temperature on the external surfaces of aircraft, which are enough to melt fuselages conventional aluminum.'s design team decided to make the jet's external skin of titanium alloy to which shielded the internal aluminum airframe. Dos conventional turbine engines, but very powerful, afterburning drove this extraordinary aircraft. Such plants had to operate through a large over speed in flight, from a takeoff speed of 334 kph (207 mph) to over 3,540 miles per hour (2,200 mph). To prevent supersonic shock waves move within the engine intake, causing blackouts, Johnson's team had to design an air intake and bypass complex system for motores.Skunk Works engineers also optimized the design of the A-12 cross section to show a low profile radar. Lockheed hoped to achieve this by forming the airframe carefully to reflect the lower transmitted radar energy (radio waves) as possible, and by applying special paint designed to absorb, rather than reflect such waves . This treatment became one of the first applications of stealth technology, but never fully met the objectives of diseño.Prueba pilot Lou Schalk flew the single-seat A-12 on April 24, 1962, after becoming the air testing accident high speed taxi. The airplane showed great promise but it needed significant technical refinement before the CIA could fly the first operational out the May 31, 1967 - a reconnaissance flight over North Vietnam. A -12s, flown by CIA pilots, operated as part of the activities special squadron 1129th Air Force as part of the "Carts." While Lockheed continued to refine the A-12, the U.S. Air Force ordered an interceptor version of the aircraft designated the YF-12A.'s Skunk Works, however, proposed a version of "specific mission" configured to carry out the post-nuclear strike reconnaissance. This system became familiar SR-71 USAF. Lockheed built fifteen A-12, which includes a special edition two-seat trainer. Two A-12s were modified to carry a drone special recognition, called D-21. The A-12 was redesignated modified M-21 . These were designed to take off with the D-21 drone, powered by a Marquart ramjet engine mounted on a tower between the rudders.'s M-21 and then threw the buzz in the air and threw it at a speed high enough ramjet engine to turn the drone. Lockheed also built three YF-12Y, but this type never went into production. Two of the YF-12Y crashed during testing. Only one survives and is on display at the Museum of the USAF in Dayton , Ohio. aft section of one of the "written off" YF-12Y, which was later used along with a static test airframe SR-71A to make the only SR-71C trainer. A SR-71 was lent to NASA and designated YF-12C. Including the SR-71B pilot trainers SR-71C and two, Lockheed constructed thirty-two Blackbirds. The first SR-71 flew on December 22, 1964. Due to extreme operating costs , military strategists decided that the more capable USAF SR-71 A-12s should replace the CIA. these were removed in 1968 after only one year of operational missions, especially Southeast Asia. 1st Strategic Reconnaissance Squadron Air Force (part of the ninth Strategic Reconnaissance Wing) took over the missions, flying the SR-71 from spring 1968.Después Air Force began to operate the SR-71, it acquired the name Official Blackbird - for black special paint that covered the airplane. This paint was formulated to absorb radar signals, to radiate some of the tremendous heat generated by the friction of the fuselage of the air, and to camouflage the aircraft against the dark sky altura.La large experience in the A-12 program convinced the Air Force that flying the SR-71 safely required two crew members, a pilot and reconnaissance systems officer (RSO). The RSO works with the wide range control systems and defense installed in the airplane. This equipment includes a sophisticated electronic countermeasures (ECM) that could jam most acquisition and selection of radar. Besides a number of advanced cameras, high resolution, the aircraft also could carry equipment designed to record the strength, frequency and wavelength of signals emitted by communications and sensor devices such as radar. The SR-71 was designed to fly into hostile territory, avoiding interception with its high speed, high altitude. could operate safely at a speed of Mach 3.3 at an altitude over sixteen miles, or 25,908 m (85,000 ft) above the ground. the crew had to wear costumes pressure similar to those used by astronauts. Such suits are required to protect the crew in case of loss of cabin pressure while in sudden operación.Para altitudes up and browse at supersonic speeds, the Blackbird Pratt & Whitney J-58 engines were designed to operate continuously in afterburner. Whilst this seems to dictate high fuel flows, the Blackbird actually achieved its best "gas mileage," in terms of air nautical miles per pound of fuel burned, during the Mach 3 + cruise. A typical flight Blackbird recognition may require several aerial refueling operations of a ship in the air. Whenever the SR-71 refueled, the crew had to descend to the tanker's altitude, usually around 6000 meters to 9,000 m (20,000 to 30,000 ft), and slow the airplane to subsonic speeds. As the speed decreases, so did frictional heat. This cooling effect caused skin panels of the aircraft to reduce the size considerably, and those covering the fuel tanks contracted so much that fuel leaked, forming a distinctive vapor trail as the tanker topped off the Blackbird. As soon as the tanks were filled, the jet's crew disconnected from the tanker , relit the turbo, and again rose to great altura.Los Air Force pilots flew the SR-71 from Kadena AB, Japan, throughout its operational career but other bases hosted Blackbird operations, too. The ninth SRW occasionally deployed from Beale AFB, California, to other locations to carryout operational missions. Cuban missions were transferred directly from Beale. The SR-71 did not begin to operate in Europe until 1974, and only temporarily. In 1982, when he founded the U.S. Air Force two aircraft at Royal Air Force Base Mildenhall to fly monitoring mission in Eastern Europe Este.Cuando the SR-71 became operational, orbiting reconnaissance satellites had already replaced manned aircraft to gather information from sites deep within Soviet territory. Satellites can not cover every geopolitical hotspot so the Blackbird remained a vital tool for global intelligence gathering. On many occasions, pilots and RSOs flying the SR-71 provided information which was vital in the formulation of U.S. foreign policy successfully. Blackbird crews provided important information about the 1973 Yom Kippur War, the Israeli invasion of Lebanon and its aftermath, and pre-and post-strike imagery 1986 raid conducted by American air forces on Libya. In 1987, Kadena-based SR-71 crews flew several missions over the Persian Gulf, revealing Iranian Silkworm missile batteries that threatened commercial shipping and American escort vessels . As the performance of surveillance systems based in space grew, along with the effectiveness of air defense networks based on land, the Air Force started to lose enthusiasm for the expensive program and the ninth SRW ceased SR-71 operations in January 1990. Despite protests by military leaders, Congress revived the program in 1995. Continued discussions on operating budgets, however, soon led to final termination. The National Aeronautics and Space preserved two SR-71As and the SR-71B for high research projects and flew these airplanes speed up 1999.El March 6, 1990, the service career of a Lockheed SR-71A Blackbird ended with a flight without unprecedented. This special plane Air Force gave the serial number 64-17972. Lt. Col. Ed Yeilding and his RSO, Lieutenant Colonel Joseph Vida, flew this aircraft from Los Angeles to Washington DC in 1 hour, 4 minutes and 20 seconds, averaging a speed of 3,418 kilometers per hour (2.124 mph). At the end of the flight, '972 landed at Dulles International Airport and rolled under the custody of the Smithsonian National Air and Space Museum. At that time, Lt. Life Colonel 1392.7 hours recorded flight of blackbirds, more than any other member of the SR-71 particularly tripulación.Este was also flown by Tom Alison, a former National Air and Head of Collections Management Space Museum. Flying with Detachment 1 at Kadena Air Force Base, Okinawa, Alison logged more than a dozen '972 operational missions. The plane went twenty-four years in the active duty Air Force and accumulated a total of 2801.1 hours of vuelo.Envergadura: 55 '7 "Length: 107'5" Height: 18'6 "Weight: 170 000 LbsReferencia and Readings: Crickmore, Paul F.
