Mars surface thermal environment simulation system

Abstract

The invention discloses a Mars surface thermal environment simulation system. The Mars surface thermal environment simulation system includes a low pressure wind speed simulation system, a low pressure wind speed measurement system, a gas temperature control system, a gas pressure control system and a Mars rover attitude control system, wherein the low pressure wind speed simulation system utilizes a vacuum container to perform modification, adds an air channel, a fan, a flow deflector, a rectification net and other devices in the vacuum container, and employs the mode of direct current gas absorption to realize 0-20m / s uniform wind speed simulation. The Mars surface thermal environment simulation system completes low pressure wind thermal balance test of the Mars rover, completes the thermal design verification in the special environment, and can provide thermal test environment conditions for a detector or load of the Mars environment to perform the related test verification.

Description

technical field [0001] The invention belongs to the technical field of thermal experiments on the ground of spacecraft, and specifically relates to a system for simulating thermal environments such as gas, temperature, pressure, and wind speed on the surface of Mars on the ground. Attitude control, etc., to realize the real simulation of the thermal environment on the surface of Mars. Background technique [0002] As the closest terrestrial planet to Earth, Mars has become one of the preferred targets for human deep space exploration due to its unique scientific value and technological leaps, and has become the focus of deep space exploration in the world in recent years. For our country, the moon is the first step in deep space exploration, and Mars exploration is the beginning of interplanetary exploration, which plays an important role in linking the past and the future. [0003] During the entire mission, the Mars rover needs to fly from the ground to Mars, which is abo...
