Description

technical field [0001] The present application relates to the technical field of dynamic simulation of the atmospheric environment of extraterrestrial planets, in particular to a temperature and pressure control method for a dynamic simulation temperature and pressure control system of the atmospheric environment of extraterrestrial planets. Background technique [0002] With the development of my country's deep space exploration technology, new requirements have been put forward for space environment simulation. Among the terrestrial planets, Mercury and Venus, and among the gas giant planets, Jupiter and Saturn all have environmental conditions different from the vacuum environment. The atmospheric environment of Venus presents the following characteristics: 1. The pressure increases as the height decreases, and the pressure on the surface of Venus is about 92bar; 2. The temperature increases as the height decreases, and the temperature on the surface of Venus is about 735...
