How does reheat increase jet engine thrust

A jet engine can produce more thrust by either accelerating the gas to a higher velocity or ejecting a greater mass of gas from the engine. Designing a basic turbojet engine around the second principle produces the turbofan engine, which creates slower gas, but more of it. See more An afterburner (or reheat in British English) is an additional combustion component used on some jet engines, mostly those on military supersonic aircraft. Its purpose is to increase thrust, usually for supersonic flight, … See more A jet engine afterburner is an extended exhaust section containing extra fuel injectors. Since the jet engine upstream (i.e., before the turbine) will use little of the oxygen it ingests, additional fuel can be burned after the gas flow has left the turbines. When the … See more In heat engines such as jet engines, efficiency is highest when combustion occurs at the highest pressure and temperature possible, and expanded down to ambient pressure … See more Jet-engine thrust is an application of Newton's reaction principle, in which the engine generates thrust because it increases the See more Thrust may be increased by burning fuel in a turbofan's cold bypass air, instead of the mixed cold and hot flows as in most afterburning turbofans. An early augmented turbofan, the Pratt & Whitney TF30, used separate burning zones for the … See more Due to their high fuel consumption, afterburners are only used for short duration, high-thrust requirements. These include heavy-weight or short runway take-offs, assisting catapult launches from aircraft carriers, and during air combat. A notable exception is … See more Afterburning has a significant influence upon engine cycle choice. Lowering fan pressure ratio decreases specific thrust (both … See more WebJan 14, 2024 · The recoil (or thrust) depends in part upon the speed of the gases ejected from the rear of the engine. That in turn depends upon the degree to which the speed of the gasses is increased by the constraining effect of the nozzle.
