PDE

   Pulsed Detonation Engine. This engine creates an explosion in the rear of a chamber which produces a shock wave which travels at about Mach 4 to the front of the chamber. This shock wave compresses a fuel-oxidizer mixture which is then detonated. Then the shock wave bounces off the front of the chamber, and pushes the combustion products out of the thrust nozzle. This creates a high amount of thrust with a minimum of fuel. The PDE engine is lightweight, fuel efficient, can operate in or out of our atmosphere and can propel a ship at speeds around 5,632 kilometers (3,500 miles) per hour.
