Abstract

Lift capacity is the key performance of the launch vehicle, and high chemical energy bi-propellants are commonly used for the modern large liquid rockets. The residual unburned propellant has a strong effect on the lift capacity and the lift efficiency, especially for the orbital stages. In this paper, the bias residual control of high mixture ratio propellant is studied, three models, including equal-probability depletion model (EPDM), equal-mass residual model(EMRM) and optimum residual model(ORM) are analyzed. Comparing with the traditional equal-probability depletion, the bias residual control of bi-propellants, especially for LOX and LH2, is benefit to the lift capacity. The effect between EMRM and ORM on the residual unburned propellant is negligible, and the EMRM is preferred in engineering.
高混合比双推进剂偏倚残留控制研究
运载火箭的关键性能是升力,现代大型液体火箭常用高化学能双推进剂。剩余的未燃推进剂对升力和升力效率有很大的影响,尤其是对于轨道级。本文研究了高混合比推进剂的偏余控制,分析了三种模型,包括等概率损耗模型(EPDM)、等质量剩余模型(EMRM)和最优剩余模型(ORM)。与传统的等概率损耗相比,双推进剂,特别是LOX和LH2推进剂的偏余控制有利于提高升力。EMRM和ORM对剩余未燃推进剂的影响可以忽略不计,工程上优选EMRM。
