Abstract:

The theoretical sea-level performance of an explosion jet-propulsion engine similar to the one used in the German flying bomb was computed to show the effects on performance of heat added and supercharging and a comparison was drawn between the performance of the explosion jet-propulsion engine and the constant-pressure jet-propulsion engine. The explosion jet-propulsion engine was found to be more efficient than the constant-pressure jet-propulsion engine at compressor pressure ratios below 3.0 when the maximum gas temperature of the constant-pressure engine is 1600 deg F. With more efficient compressors and higher gas temperatures, however, the constant-pressure jet-propulsion engine is more efficient. The compressor for the constant-pressure jet-propulsion engine absorbs more power than the compressor for the explosion jet-propulsion engine when the two engines develop the same power.
