以火箭橇试验平台为载体，针对某固体火箭发动机在特定飞行过载条件下出现的不稳定燃烧现象，提出了地面动态验证方法和测试手段，并针对模拟飞行试验的特殊性从测试系统构建、系统标定、设计飞行过载、数据分析等方面进行了分析研究。数据分析表明：火箭橇试验能够模拟飞行试验的环境条件并可实现被试发动机的无损回收，所测被试品的性能参数更接近真实飞行环境的数值，进而为飞行试验提供更加真实可靠的数据，或者用于还原飞行故障的激励条件以便准确的进行故障定位。

Based on the rocket sled test platform as the carrier,in allusion to a solid rocket motor under the condition of certain flight overload phenomenon of unstable combustion,we put forward ground dynamic verification method and the test method. Aimed at the particularity of simulated flight test,test system ar-chitecture,system calibration,design flight overload were analyzed in aspects of research and data analy-sis. The data analysis show that the rocket sled test can simulate flight test environmental conditions and can realize the participants lossless recovery of engine,and the sample measured by the performance pa-rameters is closer to the real value of flight environment,thus to provide a more reliable data for flight test, or to restore flight fault incentive conditions so that to have the accurate fault location.
