Methods and apparatus for modeling pulsed detonation gas turbine engines

A modeling system enables modeling a gas turbine engine including a pulse detonation system. The modeling system comprises a computer comprising a processor, and at least one database coupled to the computer. The processor is programmed to predict characteristics of the pulse detonation system, and predict characteristics of the gas turbine engine using the predicted characteristics of the pulse detonation system for engine cycle design and off-design performance mapping.
