An afterburner (or a reheat) is an additional component present on some jet engines, mostly military supersonic aircraft. Its purpose is to provide an increase in thrust, usually for supersonic flight, takeoff and for combat situations. Afterburning is achieved by injecting additional fuel into the jet pipe downstream of (i.e. after) the turbine. The advantage of afterburning is significantly increased thrust; the disadvantage is its very high fuel consumption and inefficiency, though this is often regarded as acceptable for the short periods during which it is usually used.
Pilots can activate and deactivate afterburners in-flight, and jet engines are referred to as operating wet when afterburning is being used and dry when not. An engine producing maximum thrust wet is at maximum power, while an engine producing maximum thrust dry is at military power.
Jet-engine thrust is governed by the general principle of mass flow rate. Thrust depends on two things: the velocity of the exhaust gas and the mass of that gas. A jet engine can produce more thrust by either accelerating the gas to a higher velocity or by having a greater mass of gas exit the engine. Designing a basic turbojet engine around the second principle produces the turbofan engine, which creates slower gas but more of it. Turbofans are highly fuel efficient and can deliver high thrust for long periods, but the design trade-off is a large size relative to the power output. To generate increased power with a more compact engine for short periods, an engine requires an afterburner. The afterburner increases thrust primarily by accelerating the exhaust gas to a higher velocity. While the mass of the fuel added to the exhaust does contribute to an increase in exhaust mass, this effect is small compared to the increase in exhaust velocity.
Two F-22 Raptors take off from Austin Straubel Intl Airport in full afterburner in preparation for the Green Bay Packers flyover on 11/16/14.

F-16 engine test with full afterburner on kjevik airforce base.
Testing new afterburner on my diy gasturbine powered kart, this is a similar engine to the one in Dan Goodwins , Trident Peel car that set a new world record for a peel trident at Santa Pod's, Flame and Thunder 2014. If you would like to know more about these engines look on facebook for diy gasturbines or www.diygt.org

Atrocious crash, altitude of terror
The skies are red, assault on civil liberty
Theft and deceit, weak quest for revenge
Invade and destroy their prideless land
Invaluable words of trust
Written laws of ethnic cleansing
Towards the inwards, invidious and beloved
Irrelevant violence focused on the balance of time
[Repeat 2nd verse]
Kingdom come, or just some lunacy?
Monster of urban history
Atheist, or a freak of nature?
Morals set aside, a living philosophy
[Repeat 1st verse]
Afterburner - Unrelieved and unbound
Afterburner - Uncalled and uncared
Afterburner - Unallied and unalike
Afterburner - Black mark in history
