JET ENGINES FOLLOWS BRAYTON CYCLE

EFFICIENCY

COMPARISION BETWEEN TURBOJET AND TURBOFAN

TURBOJET ENGINE

Generates more Thrust due to high exhaust speed.

Low frontal area.

Relative simplicity.

TURBOFAN ENGINE

More efficient thus commercially used.

Much more quiet.

Subsonic speed

Uses of Turbojet and Turbofan Engines

Military graded Fighter jets

Cruise missiles

Commercial aeroplanes.

Thanks!Any questions?
