Flight Effectiveness Evaluation of Deep-Space Reentry and Return Based on the ADC Model

Spacecraft flight effectiveness evaluation is an indispensable and important link in whole-stage test verification and on-orbit flight result evaluation. In allusion to the deep-space high-speed saltatory reentry and return flight test, an evaluation scheme of spacecraft flight effectiveness based on ADC model is proposed. In the study, the flight mission profiles are divided to establish the index evaluation system facing deep-space reentry and return process while the ADC effectiveness model is analyzed and calculated. Meanwhile, by virtue of the effectiveness quantification function, the capability metric of each mission profile is calculated, thus solving the tricky problem that the system target completion capability is not easily described quantitatively, and realizing the scientific quantitative assessment of autonomous flight capability in the navigation courses such as the establishment section, the reentry section and the leaping section, which is of certain reference significance for the subsequent effectiveness evaluation of the probe systems such as unmanned Mars or small celestial body sampling return.
