The first jet engine with after-burner was the E variant of Jumo 004.
Jet-engine thrust is an application of Newton's reaction … See more

A jet engine afterburner is an extended exhaust section containing extra fuel injectors. Since the jet engine upstream (i.e., before 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

The Caproni Campini C.C.2 motorjet, designed by the Italian engineer Secondo Campini, was the first aircraft to incorporate an afterburner. The first flight of a C.C.2, with its … 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 the fan pressure ratio decreases specific thrust (both dry and wet afterburning), but … See more
