Calculating performance of pulse detonation turbo engine

Calculating performance of PDTE can provide important data for design and further experiment. Based on the theory of ZND detonation wave and cycle analysis, a model (ZND cycle analysis method, model-1) to calculate the performance of PDTE was established. The model and former thrust wall model (model-2) with PDC characteristic chart method (model-3) was compared. And using the three models the design point performance of a PDTE was calculated. The result shows that, compared with model-2 the error of specific thrust (F_S) by using model-1 reduces 1.75%. And the error of specific fuel consumption (sfc) reduces 4.04%. Thus model-1 is more precise than model-2.Compared with model-3 which need more experiment data the method-1 is more convenient. This model can be used to fast evaluate the performance of PDTE. The change of performance gain of PDTE was calculated with the change of flight state.
