Conclusions With Respect To Pulse Detonation Cycles

The three pulse detonation engine systems are compared in a single table in similar manner to the continuous engine cycles. For a vehicle powered by a conventional continuous rocket engine, the OWE is 76 metric tons; the equivalent PDR OWE is 70 metric tons because of the lesser total vehicle volume and the lesser propellant pumping hardware and weight. The assumption made was that the engine weight is the same as an equivalent thrust conventional rocket engine. This is yet to be demonstrated with operational engine weights, but it is a reasonable expectation considering the much less complicated hardware required. With these considerations, the OWE of 70 metric tons is equivalent to the conventional all-rocket. For other propulsion systems the OWE is 70 tons plus any differential weight for the propulsion system. The TOGW for the three systems is:
