Comprehensive environment heat balance test system for Mars probe single-machine product

Abstract

The invention discloses a comprehensive environment heat balance test system for a Mars detector single-machine product. The system comprises a Mars environment simulation chamber, a solar irradiationsimulation system, a Mars atmosphere simulation system, a Mars surface wind simulation system, a temperature control system and a test piece support system, wherein the Mars environment simulation chamber is a horizontal and capsule-shaped cabin body, container gates which can be opened are arranged at the two ends of the cabin body, and the Mars environment simulation chamber is mainly used forforming a closed space without obvious leakage and maintaining a special atmospheric environment in the cabin. The system can provide comprehensive stress environment tests of five parameters including gas atmosphere, wind speed, pressure, solar irradiation and environment temperature on the surface of Mars, and is easy to operate and good in generalizability.

Description

technical field [0001] The invention belongs to the technical field of spacecraft ground environment simulation test equipment. Specifically, the invention relates to a five-integrated ground comprehensive test equipment that can simultaneously simulate the gas atmosphere, wind speed, pressure, solar irradiation and temperature environment on the surface of Mars. The invention is aimed at the field of heat balance test of Mars environment, but can be extended and applied to test simulation of stratosphere and other environmental factors including solar radiation, temperature, low pressure, wind field and the like. Background technique [0002] At present, Mars exploration has become an important goal of deep space exploration in my country's aerospace industry, and the difference between Mars exploration and other deep space exploration missions lies in the special thermal environment on the surface of Mars. In the Martian surface environment, the main factors affecting the ...

Problems solved by technology

However, for the simulation of the solar radiation of Mars rover products on the surface of Mars, infrared heating devices are mostly used for simulation. Compared with solar radiation, infrared heating devices are not collimated, and the energy distribution of the spectrum is similar to solar radiation It is very different and cannot accurately simulate the absorption ratio of the outer surface state of the product to solar radiation
