Abstract

The invention discloses a transient-state temperature simulation system and method under the low air pressure environment. Simulation of a temperature curve of the low air pressure environment is achieved under the ground environment. The system is composed of a compressor, a heat exchanger, an air regulator, an electric furnace, a heat sink and a vacuum container. The adjustable environment temperature within 150K to 350k range is achieved in the vacuum container by controlling the temperature of the heat sink. The simulation method is correspondingly disclosed as well. Transient-state temperature simulation under the low air pressure environment is achieved, and accurate temperature control of transient-state temperature simulation at the corresponding low air pressure under the condition of convective heat transfer is achieved.

Description

technical field [0001] The invention belongs to the technical field of spacecraft ground environment tests, and in particular relates to a transient temperature simulation method in a low-pressure environment. The method realizes the simulation of a low-pressure environment temperature curve in a ground environment. Background technique [0002] Mars is the closest planet to Earth and the most explored by humans. The surface of Mars has an atmosphere of 600-1000Pa, mainly composed of carbon dioxide, and the surface temperature varies in the range of -110-20°C. Therefore, the Martian environment is more complicated than the conventional orbital environment. There have been many Mars probes in history, due to insufficient understanding of the environment, they failed or partially failed after reaching the surface of Mars. At present, the aerospace agencies of various countries are more inclined to carry out comprehensive environmental tests on the Mars probe on the ground, in...
