Presentation Transcript

  1. What is a Pulse Detonation Engine? One of the newest and most exciting areas of pulse-jet development is the Pulse Detonation Engine (PDE). While they work on similar principles to a regular pulsejet, the PDE has one very fundamental difference -- it detonates the air/fuel mixture rather than just allowing it to simply deflagrate (burn vigorously).

  2. Advantages New Technology Improved fuel efficiency Greater operational range Higher Altitudes Higher Mach Numbers (0 – 4+) Longer Flight Range Reduced Flight Costs Simpler Mechanical Construction No Pre - Compression Required Dual Operational Mode for Single-Stage to Orbit (SSTO) Vehicle

  3. Conceptual Advantages II • High Thrust Density • High Specific Impulse • Significant Static Thrust, • Natural Geometry for Integration into a Combined Cycle Engine

  4. How do PDEs work?

  5. Design Challenges • DDT (Deflagration to Detonation Transition) • Inlet pressure ratio • Valve configurations • Overall injector ignition timing • Potential Fuels • Material selection
