Major applications. Lockheed A-12. 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.
Aircraft engine performance is measured at baseline parameters of a standard atmosphere (29.92” of mercury) at 15 °C. Weather may be a physical barrier to aircraft operation, as it is in the case of forecast of hail or volcanic ash, because of the risk of serious damage to all the engines installed on the aircraft.

Specific impulse, sea-level. 3,600 seconds (1.0 lb/ (lbf⋅h); 35 km/s) [ 3] SABRE ( Synergetic Air Breathing Rocket Engine[ 4]) is a concept under development by Reaction Engines Limited for a hypersonic precooled hybrid air-breathing rocket engine. [ 5][ 6] The engine is being designed to achieve single-stage-to-orbit capability, propelling ...
The RL10 is a liquid-fuel cryogenic rocket engine built in the United States by Aerojet Rocketdyne that burns cryogenic liquid hydrogen and liquid oxygen propellants. Modern versions produce up to 110 kN (24,729 lb f) of thrust per engine in vacuum. Three RL10 versions are in production for the Centaur upper stage of the Atlas V and the DCSS of ...
WZ-551A replaced the water-cooling engine with the air-cooled version, [10] thus having better reliability, cross-country capability and engine performance at high-altitude regions. [16] One distinct visual difference between WZ-551A and its predecessors is that for WZ-551 (Type 90) and WZ-523, there's a significant gap between the front axle ...
6.5: 6,498 cc (396.5 cu in); bore x stroke: 95.0 mm × 76.4 mm (3.74 in × 3.01 in), compression ratio: 11.8:1 cylinder block & crankcase cast aluminium alloy cylinder heads & valvetrain cast aluminium alloy; four valves per cylinder, 48 valves total, double overhead camshaft aspiration
Cut out 4 (14" x 12") rectangles of foil. In a medium heatproof bowl, microwave pecans, brown sugar, and rum in 15-second increments, stirring between each, until bubbling and thick, about 2 ...
