Lunar-earth high-speed reentry and return flying quality evaluation method

Abstract

The invention discloses a lunar-earth high-speed reentry and return flying quality evaluation method, which comprises the following steps of firstly, reading flight stage mark parameters in a remote signal, confirming mission profiles, start time and end time which are corresponding to the flight stage mark parameters, and extracting sub flying targets in one-to-one mapping with the mission profiles; secondly, confirming a constraint condition set of each sub flying target and an index set corresponding to each constraint condition, respectively carrying out number normalization on quantitative indexes and qualitative objects; finally, confirming an ability function value of each constraint condition and an ability quantized value of each mission profile, and calculating a lunar-earth high-speed reentry and return flying ability quantized value. The lunar-earth high-speed reentry and return flying quality evaluation method realizes scientific evaluation of the autonomous flight ability in the processes such as a lunar-earth transition section, a navigation establishment section, a reentry section and a springing section, and solves the problem that the target completion ability of a flying machine is not easy to quantitatively evaluate during the lunar-earth high-speed reentry and return full-mission simulation flight test.

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...
