摘　　要：脉冲爆震发动机作为一种新兴的动力装置 ,以其优越的性能受到了越来越高的重视。该文简要介绍了基于非稳态燃烧的脉冲爆震发动机有关问题 ,并采用一维非定常流及一维定常爆震波 (ZND)数学模型 ,确立了脉冲爆震发动机主要性能参数的计算方法。最后将算例的计算结果与常规液体火箭发动机及固体火箭发动机的相关参数作了对比 ,脉冲爆震发动机具有更优越的整体性能 ,因此 ,有必要对它进行更进一步的研究。As a new type of engine, Pulse Detonation Engine (PDE) is being paid more and more attention. Some related problems of PDE were introduced in this paper. Unlike other types of engine, PDE worked in unsteady combustion condition. Based on one-dimensional unsteady flow and one-dimensional steady detonation wave (ZND model), a method of calculating the performance parameters of PDE was carried out.When calculations are compared with the performance parameters of solid engine and liquid engine,it is concluded that PDE has very superior performance. It is necessary to continue research on PDE.
