Why do pilots need afterburner?

When a jet needs an extra kick to launch from an aircraft carrier, punch past Mach 1, or evade enemy weapons, it uses its afterburner. One hallmark of an afterburning engine is inefficiency: Using it guzzles up to three times as much fuel, so pilots typically limit its use to a few minutes per mission.

What connects to the throttle body?

The throttle body is located between the air cleaner and the intake manifold of the engine. The throttle body is connected to the gas pedal of your vehicle with a linkage or flexible cable, which moves the throttle shaft when the gas pedal is depressed.

What is an afterburner in an engine?

An afterburner is nothing but a set of fuel injectors, a tube and flame holder that the fuel burns in, and an adjustable nozzle. A jet engine with an afterburner needs an adjustable nozzle so that it can work both with the afterburners on and off. The disadvantage of an afterburner is that it uses a lot of fuel for the power it generates.

Why does a jet engine with an afterburner need a nozzle?

A jet engine with an afterburner needs an adjustable nozzle so that it can work both with the afterburners on and off. The disadvantage of an afterburner is that it uses a lot of fuel for the power it generates.

How do airplanes use afterburners?

Therefore most planes use afterburners sparingly. For example, a military jet would use its afterburners when taking off from the short runway on an aircraft carrier, or during a high-speed maneuver in a dogfight. The following pictures, taken at the Virginia Air and Space Museum, show you some of the details of an afterburner-equipped engine.

What is the maximum thrust a jet can produce with afterburner?

Maximum thrust with afterburner 15,660 daN (each 7’830 daN) Some airplanes need the afterburner to reach supersonic speed because the “normal” use of the jet turbine doesn’t generate enough thrust. Using the turbine in “normal” mode (without afterburner) is also called “military power” or “dry”.
