3. Introduction
PDE is a propulsion technology that can be used in aviation industries
Main objective of PDE is to develop efficient engine that can be used at high speed & at high altitudes.

4. Various propulsion engine are ramjet engine, scramjet engine, pulse jet engine.
PDE is similar to pulse jet engine. the diffrence is that PDE detonate their fuel rather than deflagrate.

5. Deflagration v/s Detonation
Deflagration is process of burning the fuel rapidly with the flame that travel with subsonic speed.it is also called subsonic combustion
Detonation is a violent reaction, violent release of confined energy, usually accompanied by a loud sound and shock waves. It is also called supersonic combustion

6. Principle of engine

7. Configuration of typical pde

9. Classification of PDE Pure pulse detonation engine Combined cycle PDE
Hybrid pulse detonation engine

10. Turbofan engine Hybrid PDE

11. THURST COMPARISON OF PDE WITH CONVENTIONAL TURBOFAN

14. ADVANTAGES OF PDE: 1) The thermodynamic efficiency of pulse detonation engine is higher. 2) More efficient in specific thurst and specific fuel consumption than current ramjet engine. 3)No fuel turbopump required. 4)reduced cost and complexity than liquid propellant rocket. 5) Mechanical simplicity and high compression ratio.

15. Challenges for PDE Initiation of detonation
Frequency with which detonation has to be repeated
Materials for detonation tube needs to be developed

16. Conclusion
PDE makes excellant choice for static thurst & also thermodynamic efficiency PDE is higher than conventional propulsion engine
Can be used in aircraft at high altitudes with high speed and efficiency.
