A Method of Lunar-Earth High-Speed ​​Reentry and Return Flight Quality Evaluation

Abstract

The invention discloses a method for evaluating the quality of moon-earth high-speed reentry and return flights. Firstly, the flight stage flag parameters in the telemetry signal are read, the task profile corresponding to the flight stage flag parameters and the corresponding start time and end time are determined, and the extracted The sub-flight targets that are mapped one by one with the mission profile; then determine the set of constraints for each sub-flight target and the index set corresponding to each constraint, and perform numerical normalization on the quantitative indicators and qualitative targets, and finally determine each constraint The capability function value of the condition, the capability quantification value of each task profile and the capability quantification value of each task profile calculate the moon-earth high-speed re-entry and return flight capability quantification value, and the present invention realizes the moon-earth transfer segment, navigation establishment segment, re-entry The scientific evaluation of the autonomous flight capability of the entry and exit stages solves the difficult problem of quantitative evaluation of the aircraft's target completion ability in the moon-earth high-speed re-entry and return full-mission simulated flight verification.

Description

technical field [0001] The invention relates to a flight quality evaluation method, in particular to a moon-earth high-speed reentry flight quality evaluation method, belonging to the field of spacecraft system-level test data evaluation. Background technique [0002] my country's first lunar-earth high-speed re-entry and return flight has the characteristics and difficulties of high re-entry speed, long re-entry voyage, harsh re-entry thermal environment, and complex re-entry guidance and control modes. It must be fully simulated on the ground before going to the sky. Orbit full-mission flight test to verify the correctness of the full-cycle on-orbit flight process control strategy and flight logic composed of multiple mission profiles. In order to effectively measure the pros and cons of the aircraft system and scientifically evaluate the simulated flight results, it is necessary to establish a set of quality evaluation methods for the moon-ground high-speed re-entry and re...
