Performance evaluation of lifting entry guidance for hypersonic vehicles

Aimed at the requirements and characteristics of hypersonic lifting entry vehicles, the paper brings forward the performance evaluation indexes of entry guidance, establishes the numerically scored models of performance evaluation indexes, and designs a total of 26 kinds of test missions named EG1 to EG26. According to the test cases, by means of the Monte Carlo dispersions and the individual constant disturbance simulation, each performance index of entry guidance is numerically scored. Based on the weighted allocation strategy, a comprehensive evaluation on entry guidance law can be completed. Finally, the concrete steps and process about the evaluation method of entry guidance performance is given, which can be an important references and basis of performance evaluation on entry guidance for a class of lifting vehicles.
