Lockheed SR-71 The Pratt & Whitney J58 (company designation JT11D-20 ) is an American jet engine that powered the Lockheed A-12 , and subsequently the YF-12 and the SR-71 aircraft. It was an afterburning turbojet engine with a unique compressor bleed to the afterburner that gave increased thrust at high speeds.
Clarence Leonard "Kelly" Johnson (February 27, 1910 – December 21, 1990) was an American aeronautical and systems engineer.He is recognized for his contributions to a series of important aircraft designs, most notably the Lockheed U-2 and SR-71 Blackbird.
When SR-71 crews became upset that engineers were not putting enough effort into solving a constant problem with violent engine unstarts in flight, Rich considered taking a flight in the SR-71 to experience the phenomenon himself, which included having to go through the same flight physical as pilots. He did not go through with the flight.
The Pratt & Whitney J58 (JT11D-20) turbojet aero engine, which had a specific fuel requirement; namely JP-7 turbine fuel.. Turbine Fuel Low Volatility JP-7, commonly known as JP-7 (referred to as Jet Propellant 7 prior to MIL-DTL-38219 [1]) is a specialized type of jet fuel developed at Pratt and Whitney by master chemist Clarence Brown CB Eichman in 1955 for the Central Intelligence Agency ...
The Lockheed SR-71 Blackbird and XB-70 Valkyrie had well-publicised [6] [7] unstart behaviour. Other aircraft that have flown with internal compression include the Vought F-8 Crusader III, the SSM-N-9 Regulus II cruise missile [8] and the B-1 Lancer. [9]
Zip fuel research led to the use of triethylborane as an ignition agent for the JP-7 fuel used in the SR-71 Blackbird. [13] [14] One potentially lasting relic of the HEF program is an abandoned dirt airfield outside Boron, California. Marked on USGS topographical maps as "Air Force Plant #72", nothing but the airstrip and a water tank were ever ...
It was the precursor to the twin-seat U.S. Air Force YF-12 prototype interceptor, M-21 launcher for the D-21 drone, and the SR-71 Blackbird, a slightly longer variant able to carry a heavier fuel and camera load. The A-12 began flying missions in 1967 and its final mission was in May 1968; the program and aircraft were retired in June.
