Abstract :
For the analysis of liquid rocket propulsion system with independent fuel supply to the turbine one must simulate the physical processes occurring in each of its elements to determine their dynamic performance. The paper presents the dynamics equations, which describe the processes occurring in the decomposition cell, the nozzle head and the throttle tap. A general differential equation of a one-component gas generator with the throttle is carried out. The mathematical model allows to analyze and identify the main regularities of influence of input variables on the controlled quantity.
