A spacecraft soft landing simulation experiment device and simulation method

Abstract

The invention discloses a spacecraft soft landing simulation experimental device, which comprises a small angle inclined platform. A small hydraulic synchronous adjustment system is connected with a lower side of one end of the small angle inclined platform. The upper end of the small angle inclined platform is provided with a lander simulation. The lower surface of the lander simulator is provided with a floating air cushion; the upper surface of the lander simulator is attached with a light fluorescent reflector; a cold air thrust nozzle is disposed on the lateral of the lander simulator. The device also comprises a binocular computer vision system. The device utilizes an air flotation simulator and the small angle inclined platform to simulate a landing process, attitude and trajectory control in the final stage of a soft landing task of the spacecraft. The device also provides a simulation method. The experimental device can be used to verify the attitude, trajectory and landing point control performance of the landing simulator during soft landing.

Description

technical field [0001] The invention belongs to the technical fields of mechanics, control, aviation, etc., and specifically refers to a spacecraft soft landing simulation experiment device and simulation method, which can be applied to the physical simulation test of aerospace lander soft landing. Background technique [0002] With the rapid development of space science and technology, the pace of human exploration of space is accelerating. The first prerequisite for realizing missions to explore near-Earth planets and even deep space is to land precisely on the surface of celestial bodies, such as the soft landing of the moon and Mars probes. The space exploration project has huge complexity, and there are still many uncertain factors in each task link, which makes the landing spacecraft prone to insufficient landing accuracy and even mission failure. The development of future aerospace technology, especially deep space exploration missions, requires the development of hi...
