摘要/Abstract

摘要： 火星探测器着陆过程中的发动机羽流与火壤发生复杂的相互作用，一方面探测器底部的火壤表面成分及分布形式被破坏，影响探测器的着陆过程；另一方面受发动机羽流作用而扬起和悬浮的颗粒，会影响探测装置的可靠工作。针对此问题，利用数值模拟，对火星探测器着陆过程中的发动机羽流和火壤相互作用进行了研究，获得了不同发动机高度和推力下火壤颗粒的激扬高度、火坑深度和火坑宽度，通过在轨飞行数据反演对仿真算法进行了验证和评价，为火星着陆策略的制定提供了支撑。

Abstract: During the landing process of Mars Rover, there is complex interaction between the engine plume and Martian soil, which on the one hand, affects the landing process due to the destruction of the composition and distribution form of Martian soil surface at the bottom of the Rover; and on the other, affects the reliable operation of detection device due to the particles raised and suspended under the action of the engine plume.In this connection, the paper studies the interaction between engine plume and Martian soil during the landing process of Mars Rover through numerical simulation, obtains the raising height of Martian soil particles as well as pit depth and width under different engine heights and thrusts, and verifies and evaluates the simulation algorithm via the in-orbit flight data inversion, so as to provide a support for the formulation of Mars landing strategy.

Key words: Mars landing, plume, Martian soil, two-phase flow analysis, flight data
