Abstract: 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. 
