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.
