Abstract: The dynamic models of engine parts in a new high-performance staged combustion cycle liquid propellant rocket through the module codified were built.The lumped parameters method was used, the inertia, viscosity and compressibility of liquid were considered at the same time. However, the ordinary differential equation set can generally reflect the distributed characteristic of the flowing process in the engine.

摘要： 通过模块化编程 ,建立了新一代高性能补燃发动机启动过程的部件模型。虽然采用的是集中参数方法 ,但同时考虑了液体的惯性、粘性和压缩性 ,所以建立的常微分方程组能在一定程度上反映发动机工作过程的分布特性。
