| Abstract: | The development status and application prospect of liquid propellant rocket engine with variable thrust were summarized,and a few adjust scheme for variable thrust of turbopump-fed rocket engine were put forward;their advantages and disadvantages were analyzed,meanwhile several important aspects for adjust scheme selection of turbopump-fed rocket engine were introduced.One turbopump-fed rocket engine was regarded as a model engine to analyze the system parameter balance calculation result for all adjust schemes.Feasible system adjust schemes were determined to facilitate the engineering research and design of model engine. |
