The purpose of an after burner in a jet is to provide an increase in push off that is usually for flights that are going to takeoff, and also during combat situations.
To quickly increase their speed, jet fighters use an afterburner to increase thrust. An afterburner injects additional fuel into the hot exhaust of a jet engine, giving a quick burst of speed that also uses a LOT of fuel!
a jet engine afterburner is when you put a lot of gas to the engine and you go very fast... An afterburner (or reheat) is an additional component added to some jet engines, primarily those on military supersonic aircraft. Its purpose is to provide a temporary increase in thrust, both for supersonic flight and for takeoff (as the high wing loading typical of supersonic aircraft designs means that take-off speed is very high). On military aircraft the extra thrust is also useful for combat situations. This 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.

An F-14 can go through 2,000 gallons of jet fuel in 15 minutes when in full afterburner.
Afterburner - album - was created on 1985-10-28.
Afterburner - Fun Spot - was created in 1991.
An afterburner is a device in the engine of an aircraft which injects fuel into the exhaust system to increase thrust.
Depending upon your system, they can get a loud as 146Db. That is uncomforably loud like a military jet aircraft take-off from aircraft carrier with afterburner at 50 ft .
The Jet engines purpose is to create thrust.With out Thrust a plane would not be able to fly.
An afterburner is an additional component added to some jet engines, primarily those on military aircraft. It was originally developed for the Miles M.52 project (during the last years of World War II) where it was called a reheat jetpipe. Its purpose is to provide a temporary increase in thrust for situations such as take-off, or in military aircraft, combat or supersonic flight. This is achieved by injecting additional fuel into the jet pipe downstream of (i.e. after) the turbine. This fuel is ignited by the hot exhaust gasses and adds greatly to the thrust of the engine. Afterburning is extravagant on fuel and inefficient but this is acceptable for the short periods in which reheat is usually used. Jet engines are referred to as operating wet when reheat is being used, and dry when the engine is used without afterburner. Usage The only civilian passenger transport aircraft to use afterburners were Concorde and the Tupolev Tu-144 supersonic transport, which used them at takeoff and to minimise the time in the high drag transonic flight regime. Except for some NASA research aircraft and the White Knight of Scaled Composites, afterburners are in the regime of military fighter jets. Modern design supercruise engines have inherently high thrust and this has lessened the need for afterburner. A turbojet engine equipped with an afterburner is called an "afterburning turbojet," whereas a turbofan engine similarly equipped is called an "augmented turbofan."
The purpose for jet aircraft is to quickly transport people to far away destinations or to fight in a war against the opponents.
