摘　　要：在收集整理传统一次性运载火箭以及航天飞机常见故障的基础上,归纳总结了亚轨道飞行器(SRLV)可能存在的故障模式。针对亚轨道飞行器上升段发动机推力损失情况,利用OpenFlight仿真平台搭建亚轨道飞行器三自由度飞行故障仿真系统并进行了故障仿真,分析了推力损失对SRLV上升段飞行轨迹的影响,为后续应急返回制导研究与应急返回能力分析提供了参考。Based on frequent failures of launch vehiclebital reusable launch vehicle （SRLV） are summarizedand space shuttle, possible failure modes of subor-ascent trajectory for SRLV in the case of loss of thrust isby the ＂OpenFlight＂simulation platform. Influences onBecause of the significance of engine failure, thesimulated. The failure simulation system is builtascent trajectory of failure are analyzed by failuresimulation. The final results may provide reference for the research on abort guidance and abort capabilityanalysis in the future.
