A model requiring no empirical parameter for estimating the propulsive performances of a partially-fueled (P-F) pulse detonation engine (PDE) was proposed. The model was developed based on a hypothesis that every performance parameters obtained by integrating phenomena in one cycle are predominantly determined by energetics only. In the model, an objective P-F PDE is replaced with the equivalent fully-fueled (F-F) PDE which is a hypothetical PDE fully filled with the homogeneous mixture of the detonable and inert gases filling the objective P-F PDE. And the propulsive performances of the equivalent F-F PDE are estimated by using a previously-developed performance-estimation model for a F-F PDE. By comparing the results of the model with those of numerical simulations and experiments, the applicability of the model was verified. As results, the model reproduced the numerical and experimental results within about 25%.
