Problems solved by technology

[0005] At present, my country's Venus surface exploration mission is still in its infancy. The Venus surface exploration mission is inseparable from the research and development of detection equipment. The research and development stage of detection equipment requires a large number of simulation tests. The simulation test is inseparable from the simulation of the atmospheric environment on the surface of Venus. The atmospheric environment on the surface of Venus has the characteristics of high pressure, many gas components, and large differences. There are some trace gases in the gas components, and the content of trace gases is small. The existing industrial sensors cannot be measured. The simulated atmospheric environment on the surface of Venus has a large error

Abstract

The present application provides a gas distribution method and a gas distribution system for simulating the atmospheric environment on the surface of Venus. The method includes the following steps: S1. Determine the gas composition and content of the simulated atmospheric environment; S2. Set the SO 2 , CO, COS, H 2 S, HCL and HF are respectively associated with CO 2 Mixed gas distribution concentration; S3, using the dilution method, separate the SO 2 , CO, COS, H 2 S, HCL and HF with CO 2 Carry out gas distribution to obtain six kinds of mixed gases; S4, calculate six kinds of mixed gases, CO 2 , N 2 and H 2 The air intake amount of O (gaseous state); S5, the six kinds of mixed gases obtained in step S3 are passed into the atmospheric environment simulation container in turn; S6, N 2 and H 2 O (gaseous) is passed into the atmospheric environment simulation container; S7, the CO 2 Pass into the atmospheric environment simulation container; S8, end of gas distribution. This application can accurately complete the simulation of the gas composition of the atmospheric environment on the surface of Venus.

Description

technical field [0001] The present application relates to the technical field of extraterrestrial planet gas environment simulation, in particular to a gas distribution method and a gas distribution system for simulating the atmospheric environment on the surface of Venus. Background technique [0002] Venus is the closest planet to Earth in the solar system, and is similar in size and mass to Earth. The surface pressure of Venus is about 90 times that of Earth, and its main component is carbon dioxide. The surface of Venus has extremely high temperatures, which can reach up to 760K. The composition of the Venus atmosphere is mainly composed of carbon dioxide and nitrogen, the rest of the composition is mainly composed of argon and carbon monoxide, a small amount of water vapor (compared to Earth), a large amount of sulfur dioxide (compared to Earth), while small amounts of HCL and HF are also observed . Table 1 briefly compares the gas composition and content of the Venus...
