| Abstract: | This article adopts the method of instantaneous pressure equilibrium of variational burning surface of powder in solid rocket engine and flow-rate equilibrium relation to calculate ex-actly the performance of powder gas in the front of the turbine nozzle. Various performance parame-ters of the powder gas in the front of the turbine nozzle were obtained. These parameters will be helpful to the research of turbine start and engine acceleration performances. |
