Specific thrust is the thrust per unit air mass flowrate of a jet engine (e.g. turbojet, turbofan, etc.) and can be calculated by the ratio of net thrust/total...

propellant or a jet engine using fuel, generates thrust. A propulsion system with a higher specific impulse uses the mass of the propellant more efficiently...

Thrust-specific fuel consumption (TSFC) is the fuel efficiency of an engine design with respect to thrust output. TSFC may also be thought of as fuel...

velocity, giving much more thrust per unit energy (lower specific thrust). Both airstreams contribute to the gross thrust of the engine. The additional...

reduce aircraft drag at supercruise, SST engines require a high specific thrust (net thrust/airflow) to minimize the powerplant's cross-sectional area. This...

mostly those on military supersonic aircraft. Its purpose is to increase thrust, usually for supersonic flight, takeoff, and combat. The afterburning process...

greater net thrust to be available at slow speeds. Thus civil turbofans today have a low exhaust speed (low specific thrust – net thrust divided by airflow)...

is usually placed before "specific" in the full term (e.g., "thrust-specific fuel consumption"). Named and unnamed specific quantities are given for the...

In orbital mechanics, low-thrust relative transfer is an orbital maneuver in which a chaser spacecraft covers a specific relative distance relative to...

Thrust reversal, also called reverse thrust, is the temporary diversion of an aircraft engine's thrust for it to act against the forward travel of the...
