In order to meet experimental research, theoretical analysis verification and numerical prediction methods of Mars environment, Mars wind tunnels are built in the United states, Europe and Japan successively from the 80 th century, Mars surface atmospheric environment is simulated, and research works such as Mars wind and wind erosion process are developed. The subsonic low-density wind tunnel field in China still belongs to a blank state, and research and construction of a Mars dust storm environment simulation device are of great significance to the Mars detection task in China.
The spark atmosphere contains 95.3% carbon dioxide, 2.7% nitrogen, 1.6% argon and a small amount of other gaseous components. The surface average air pressure is only 700Pa, and the gravity value is 40 percent of the earth. The earth surface of the mars is very rough, and the mars wind is generated due to the rising and falling change of the temperature in the process of the alternation of the mars day and night. When the wind speed exceeds a certain scale and is maintained for a certain time, a Mars storm is formed. The wind speeds in different areas are greatly different, the average wind speed in the daytime is 6-8m/s, and the wind speed in a dust storm can reach 100 m/s. Therefore, the key technical parameters of the Mars environment simulation are as follows: CO 2 2 An atmosphere; low air pressure; wind speed; and (5) a sand and dust environment.
The high-speed dust storm environmental effect on the surface of the spark simulated by the conventional spark environment simulation device has poor authenticity, and only a single rotational flow type can be generated, so that the device is not beneficial to the research of people on the real spark dust storm environment.
