Conclusions from Zero - D Model

• Vacuum Conditions:

  • Depends on Temperature Only
    • Independent of Pressure
  • No Advantage for Constant Volume Combustion
  • PDE Performance Equal to Rocket

• Finite Back-Pressures

  • Depends on P and T
  • Peak Pressure in PDE Equal to Rocket Pressure
    • Rocket Performance Exceeds PDE
  • PDE Pressure before Detonation Equal to Rocket Pressure
    • PDE Performance Exceeds Rocket
