Abstract:
Thrust regulation is an effective way for improving the adaptability of liquid rocket engine and launch vehicle．It is an emphasized characteristic for advanced liquid rocket engine． Staged combustion cycle is the most advanced cycle of liquid rocket engifie．Therefore in the staged combustion cycle engine study thrust regulation should be introduced．The best way of thrust regula— tion for staged combustion cycle engine is regulating the less flowrate propellant of the preburner． Considering the effect of the thrust regulation on the preburner temperature，upwards regulation should not be too large，and the downwards regulation can be in a larger range．The impact of the thrust regulation on specific impulse is much less and can be neglected，Thrust regulation also has less effect on mixture ratio，but it must be considered for deep regulation．Thrust regulation rate should not be too high and lower than 20％per second is prefered．
