How long can an F 16 fly on afterburner?

In full afterburner at low altitudes, the F-16 can burn in excess of 64,000 pounds an hour. At full throttle, a U.S.-variant F-16 with maximum external fuel stores has about 20 minutes until it’s on emergency reserves (which would only last an extra minute or so at full afterburner).

Why do fighter jets have flames?

Fighter jet engines use the exhaust gasses from the turbine directly to produce thrust, so there are not large amounts of non-exhaust air. The flames that you see are from a process called reheating.

Why do Russian jets have blue afterburners?

Look afterburners are present there to increase the speed of the jet and they are usually fired when you are taking off or just need to go supersonic. There is nothing as blue or orange on that.

How hot is a jet afterburner?

1700 deg. C
Since the temperature of an afterburner can reach 1700 deg. C, the flame is usually concentrated around the jet pipe axis, allowing a portion of the discharge gas to flow along the wall of the jet pipe and therefore maintain a safe wall temperature.

Who invented afterburner?

Undoubtedly, the first afterburner in America was built by NACA in 1944. This research was conducted in the NACA’s Lewis Flight Propulsion Laboratory and began with the de livery of the nation’s first turbojet engine—General Electric’s ISA.

What is the function of afterburner?

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.

Why do afterburners have flames?

As you already know, the mechanism of afterburner is simply to dump fuel directly into the hot and high-speed exhaust of the engine, this can explain the flames that burst out behind the craft and a very significant increase in speed.

What is the purpose of an afterburner in an aircraft?

An afterburner (or a reheat) is a component present on some jet engines, mostly those used on military supersonic aircraft. Its purpose is to provide an increase in thrust, usually for supersonic flight, takeoff, and combat situations. The afterburner increases thrust primarily by accelerating the exhaust gas to a higher velocity.

How do afterburners work in a turbine engine?

A modern turbine engine is extremely efficient, and there is still a lot of oxygen available in the exhaust stream. The idea behind an afterburner is to inject fuel directly into the exhaust stream and burn it using this remaining oxygen. This heats and expands the exhaust gases further, and can increase the thrust of a jet engine by 50\% or more.

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.

What are the advantages and disadvantages of an afterburner?

The big advantage of an afterburner is that you can significantly increase the thrust of the engine without adding much weight or complexity to the 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.
