WHAT IS JET ENGINE

It is a reaction engine.

Working principle :

NEWTON’S LAW OF MOTION. (3rd law)

It is a internal combustion engine.

Open cycle gas turbines.

TYPE OF REACTION ENGINES

The gas turbines :-

when we say a Jet engine. We commonly mean a gas turbine engine.

( air from atmosphere as working fluid)

The rocket :-

do not depend upon the atmospheric air.

( it carry oxygen in liquid form)

It carry oxygen with fuel

HISTORY OF JET ENGINE

The first jet engine was build by Egyptian scientist during 100bc

These device was known as “Aeopile”

PARTS OF JETENGINE

FAN

COMPRESSOR

TURBINE

MIXER

NOZZLE

WORKING OF JET ENGINE

Air suck from atmosphere.

Then compressed

Mixing of fuel and air..

Combustion

High velocity air exhaust through nozzle.

HOW JETENGINE WORKS

Air intake

Compressing of air

Fuel mixing

Combusting

Turbine rotery

Exhausting of air

TYPE OF JET ENGINE

RAM JET

TURB JET

TURBO FAN

TURBO PROP

TURBO SHAFT

RAM JET

It has no moving parts

It’s compression ratio depend upon forward speed.

It has no static thrust; guided missile system, space vehicle use this type of jet.

TURBO JET

The turbojet is an air breathing jet engine.

It consists of a gas turbine with a propelling nozzle.

Usually used in aircraft.
