Ideal cycle analysis of a pulse detonation engine

Pulse Detonation Engine (PDE) is expected to be one candidate for the next generation of high performance propulsion engines and power plants. The need for heavy air compression in common gas turbines could be eliminated in PDEs, allowing the operation with fewer compressor stages. This advantage wo...
