| Abstract: | A new modular method for calculating the maximum combustion chamber pressure with stage combustion cycles is proposed in this paper.The modules of the engine system are calculated iteratively in a predetermined sequence,and a modified Newton method is used to find the unknown variables of the system.This method is general for calculating the maximum chamber pressure of the liquid rocket engine with stage combustion cycles.The program based on the method is achieved by the object oriented programming.The maximum combustion chamber pressures of RD 120 and RD 704 are calculated with the program,and the calculation results are also given. |
