摘　　要：简述了泵压式变推力液体火箭发动机的现状和应用前景,提出了几种泵压式发动机推力调节方案,分析了各方案的优缺点,阐述了系统方案选择须重点考虑的几个方面.以某泵压式发动机为模型发动机,利用系统参数平衡仿真计算结果,对各种调节方案综合分析,确定了可行的系统调节方案,可用于指导模型发动机的工程研制.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.
