摘　　要：为了准确计算双组元液体推进剂运载火箭运载能力评估方法中的剩余可用推进剂折算系数,基于某运载火箭发射地球静止同步转移轨道(GTO)飞行任务,推导了末级剩余可用推进剂与运载能力对应关系,提出简化计算公式,并基于实际弹道计算程序对结果进行了数学仿真验证。结果表明:本文方法能有有效评估发射地球静止同步转移轨道飞行任务的剩余推进剂运载能力折算系数,该方法对于提升火箭运载能力评估的效率和准确性具有重要意义。In order to accurately calculate the conversion factor of remaining available propellant in the evaluation method of carrying capacity of two-component liquid propellant launch vehicle,a relationship is derived between remaining available propellant mass in final stage and rocket’s carrying capacity based on a certain type of launch vehicle launching geostationary transfer orbit(GTO)mission.A simplified calculation formula is proposed,and results are verified by mathematical simulation based on actual ballistic calculation program.It is believed that the method in this paper can effectively evaluate the conversion factor of remaining propellant in GTO mission.This method is of great significance for improving the efficiency and accuracy of the rocket’s carrying capacity evaluation.
