摘要:
分析了变推力发动机采用的双调模式，用流量调节器控制推进剂流量，流量定 位针栓式喷注器控制喷注压降，保证喷注速度基本不变。根据发动机系统特点建立了主要组 件的数学模型，并根据模型进行了仿真计算，最后对发动机前管路流阻影响进行了分析j
Abstract:
A variable-thrust engine USeS a regulator to control the flowrate and a flowrate posi· tioned pintle injector to control the injection pressure drop，thus to maintain a stable injection veloc· ity．In this paper，based on the charaeteritics of the engine system，the main components models are established and simulated．At the end，the influence of flow resistance in the pipeline upstream the engine on the engine performance is analyzed．
