Abstract:
To make a reliable engine start-up program, a series of modeling and simulation for the start-up transient characteristics of 60-ton-thrust LOX/methane rocket engine was performed. A systematic scheme for 60-ton-thrust LOX/methane rocket engine is introduced in this paper. The simulation models were enumerated and a simulation platform was established for the transient characteristics of the whole system. According to the simulation results, the ignition/start-up scheme in reservoir pressure was selected. The solution of setting up a methane turbine inlet bypass is presented for decreasing two-phase flow acceleration pressure drop. The test results show that the simulation results are well in line with the ground test data of main parameters.
