3. INTRODUCTION New concept Early experiments in 1940
Developed for boosting satellites to high orbits
Low cost
Noise reduction

4. Experimental set-up

5. ACTUAL ENGINE

6. PRINCIPLE OF ENGINE

7. 6 Stages of combustion Injection of fuel and air mixture
Initiation of detonation
Actual combustion, detonation propagates through the chamber
Detonation leaves the chamber
Rarefaction waves move in from exit
Scavenging of the combustion

8. COMBUSTION ANALYSIS

9. INLET LOSSES

10. COMBUSTOR LOSSES

11. NOZZLE LOSSES

12. SHADOWGRAPH TESTING

13. Results

14. DIFFERENCES COMPARED TO OTHER ENGINES
Combustion chamber is open
No piston is used
Combustion occurs in detonative mode

15. ADVANTAGES High thermodynamic efficiency Simple engine principle
Applicable for a wide range of velocities
Not limited to circular geometries
Can be used both in rocket and in air breathing mode

16. STATUS First experimenting on the PDE in 1940
No flying applications have been reported

17. FUTURE The length of the mixture chamber
The shape of the contraction section
Position of spark plug
Position of introduction of hydrogen
Position of reed valve

18. CONCLUSION
The pulse detonation engine has several very attractive features and has the potential of becoming an alternative to the current propulsion devices
