Concorde flew long distances at supersonic speeds. Sustained high speeds would be impossible with the high fuel consumption of afterburner, and the plane used afterburners at takeoff and to minimize time spent in the high-drag transonic flight regime. Supersonic flight without afterburners is referred to as supercruise.
In full afterburner it produces a thrust of more than 30,000 pounds-force ... Specific fuel consumption: 0.562 lb/lbf/h (57.3 kg/kN/h) (dry thrust),
The nozzle actuators use engine fuel whereas the F404 uses an engine hydraulic system. "Fueldraulic" actuators for afterburner nozzles have been used since the 1960s on the Pratt & Whitney J58 [5] and Rolls-Royce Turbomeca Adour, [6] for example. They are also used to swivel the VTOL nozzle for the Rolls-Royce LiftSystem. [7]
For the F/A-18, GE based the F404 on the YJ101 engine they had developed for the Northrop YF-17, enlarging the bypass ratio from 0.20 to 0.34 to enable higher fuel efficiency. The engine consists of a three-staged fan, seven axial stage compressor arrangement, single stage low and high pressure turbines, an augmentor, and produces maximum ...
The General Electric J79 is an axial-flow turbojet engine built for use in a variety of fighter and bomber aircraft and a supersonic cruise missile.The J79 was produced by General Electric Aircraft Engines in the United States, and under license by several other companies worldwide.
Fuel consumption: 3,977 kg/h (8,770 lb/h) and 12,695 kg/h (27,990 lb/h) (with afterburner) Specific fuel consumption : 22.14 g/(kN⋅s) (0.782 lb/(lbf⋅h)) and 47.11 g/(kN⋅s) (1.663 lb/(lbf⋅h)) (with afterburner)
It features an eight-stage axial-flow compressor powered by two turbine stages, and is capable of generating up to 2,100 lb f (9.3 kN) of dry thrust, or more with an afterburner. At full throttle at sea level, this engine, without afterburner, consumes approximately 400 US gallons (1,500 L) of fuel per hour.
The Pratt & Whitney F135 is an afterburning turbofan developed for the Lockheed Martin F-35 Lightning II, a single-engine strike fighter.It has two variants; a Conventional Take-Off and Landing variant used in the F-35A and F-35C, and a two-cycle Short Take-Off Vertical Landing variant used in the F-35B that includes a forward lift fan.
