摘　　要：面向火箭冲压组合发动机推进剂调节范围宽、调节模式多样的特点,提出以结构简单、控制方法简洁的过氧化氢/煤油电动泵供应系统来替代传统的涡轮泵系统将更具优势。针对高浓度过氧化氢高温不稳定性及相容性特点,开展基于电机驱动的过氧化氢离心泵一体化结构设计,以高功重比为目标进行过氧化氢泵设计分析。聚焦过氧化氢介质受高温易爆的问题,利用离心泵诱导轮后与泵进口之间的压差,设置了过氧化氢冷却通道,控制泵内各生热部位的温度,通过Pumplinx软件对多个状态下泵外特性及冷却流场进行仿真计算。计算结果显示,泵水力特性良好,过氧化氢温度均在安全范围。分析表明,过氧化氢电动泵结构设计方案可行。Aiming at the characteristics of wide propellant regulation range and various regulation modes of RBCC,a hydrogen peroxide/kerosene electric pump supply system with simple structure and simple control method is proposed to replace the traditional turbopump system.According to the characteristics of high temperature instability and medium compatibility of hydrogen peroxide medium,the integrated structure design of hydrogen peroxide electric centrifugal pump based on motor drive was carried out,and the design and analysis of hydrogen peroxide pump were carried out with the goal of high power weight ratio.Aiming at the problem that hydrogen peroxide medium is subject to high temperature and explosion,the hydrogen peroxide cooling channel is established to con⁃trol the temperature of each heat generating part in the pump by using the pressure difference between the centrifugal pump inducer and the pump inlet.The pump external characteristics and cooling flow field under multiple conditions are simulated by Pumplinx.The calculation results show that the pump has good hydraulic characteristics and the hydrogen peroxide temperature is within the safe range.The analysis shows that the structure design scheme of hydrogen peroxide electric pump is feasible.
