This document discusses jet engines and provides a comparison between turbojet and turbofan engines. It defines a jet engine as a reaction engine that generates thrust by discharging a fast moving jet according to Newton's laws of motion. It lists the basic components of a jet engine as a multi-stage compressor, combustor, high and low pressure turbines, and nozzle. The document notes that turbojet engines generate more thrust due to higher exhaust speeds but are less efficient, while turbofan engines are more efficient and quieter, making them more suitable for commercial use.

1. Hello!
I am ROHIT DEY,
ME 3rd year..

2. TURBOJET AND
TURBOFAN ENGINE

3. WHAT IS A JET
ENGINE?1

4. “
A jet engine is a reaction engine
discharging a fast moving jet that
generates thrust by jet porpulsion in
accordance with newton’s laws of motion.

5. TURBOFAN JET ENGINE

6. HISTORY

7. COMPONENTS OF
BASIC JET ENGINE
1) Multi stage
Compressor
2) Combustor 3) High and Low
Pressure Turbine
4) Nozzle

11. JET ENGINES FOLLOWS BRAYTON

12. EFFICIENCY

13. 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

14. Uses of Turbojet and
Turbofan Engines
 Military graded Fighter jets
 Cruise missiles
 Commercial aeroplanes.

15. Thanks!
Any questions?
