TSFC or SFC for thrust engines (e.g. turbojets, turbofans, ramjets, rockets, etc.) is the mass of fuel needed to provide the net thrust for a given period e.g. lb/(h·lbf) (pounds of fuel per hour-pound of thrust) or g/(s·kN) (grams of fuel per second-kilonewton). Mass of fuel is used, rather than volume (gallons or litres) for the fuel ...
One metric horsepower is needed to lift 75 kilograms by 1 metre in 1 second. The various units used to indicate this definition (PS, KM, cv, hk, pk, k, ks and ch) all translate to horse power in English. British manufacturers often intermix metric horsepower and mechanical horsepower depending on the origin of the engine in question. [citation ...
The FJ33 has a dry weight of less than 300 lb (140 kg), overall diameter of 18.36 in (466 mm), 38.43 in (976 mm) overall length, and produces between 1,000 lbf (4,400 N) and 1,800 lbf (8,000 N) static thrust.
Engine power is the power that an engine can put out. It can be expressed in power units, most commonly kilowatt, pferdestärke (metric horsepower), or horsepower.In terms of internal combustion engines, the engine power usually describes the rated power, which is a power output that the engine can maintain over a long period of time according to a certain testing method, for example ISO 1585.
Thrust is the force supplied by the engine and depends on the propellant mass flow through the engine. Specific impulse measures the thrust per propellant mass flow. Thrust and specific impulse are related by the design and propellants of the engine in question, but this relationship is tenuous: in most cases, high thrust and high specific ...
The Rolls-Royce Pegasus is a British turbofan engine originally designed by Bristol Siddeley. It was manufactured by Rolls-Royce plc. The engine is not only able to power a jet aircraft forward, but also to direct thrust downwards via swivelling nozzles. [1] Lightly loaded aircraft equipped with this engine can manoeuvre like a helicopter.
The GP7270 is rated at 74,735 lbf (332.44 kN) of thrust whilst the GP7277 is rated at 80,290 lbf (357.1 kN). The engine is offered with two ratings appropriate for the various A380 configurations and take-off weights: GP7270 for the 560-tonne variant, and GP7277 for the 590 tonne A380-800 freighter (which was subsequently cancelled by Airbus).
The expanding flow in the diverging section caused a forward thrust force on the exhaust nozzle: a 29% contribution to the overall propulsion system thrust at cruise. [16] During cruise at Mach 2.02 each Olympus 593 was producing around 10,000 lbf (44 kN) of thrust, equivalent to 36,000 hp (27,000 kW) per engine. [23]
