Description

Simulated lunar soil conveying device and method suitable for vacuum cabin

Technical Field

The invention relates to the technical field of lunar soil erosion simulation tests, in particular to a lunar soil simulation conveying device and a lunar soil simulation conveying method suitable for a vacuum cabin.

Background

The moon surface is in a vacuum condition and is not protected by the atmosphere, and the moon surface is covered with surface floating dust with a certain thickness due to the collision of celestial bodies. In the process that the lander falls on the lunar surface, the outlet of the engine spray pipe of the lander is continuously close to the lunar surface, the plume sprayed by the engine can impact the lunar surface, and the high-speed and high-temperature plume can have the effects of scouring and erosion on the lunar dust on the lunar surface. When plume erosion pits are deep and steep, it may cause the lander to be unstable and even topple over, greatly affecting the safety of landing, and thus an open test is required to study the evolution of erosion pits in the landing process.

In order to simulate the lunar vacuum environment, the test needs to be carried out in a vacuum cabin, the test space in the general vacuum cabin is limited, and the simulated lunar dust can pollute the vacuum cabin and a vacuum pump set, and in order to reduce the pollution degree, a simulated lunar dust protective cover is additionally arranged to prevent the simulated lunar dust from diffusing to the periphery to a certain extent, so that the test space is narrower. In order to better simulate the real environment of the moon, the test is not influenced by the simulated moon dust container, and a certain area and thickness of lunar soil are needed for carrying out the test, so that the total mass of the lunar soil often needs tens or even hundreds of kilograms, and the transportation in a narrow space without influencing the simulated moon dust state needs to be paid extra attention.

The transfer of the simulated lunar soil at present is generally prepared in advance outside the cabin, and the whole container of the simulated lunar soil is conveyed into a vacuum cabin and placed at a proper position before the test, so that high requirements on manpower are met. In addition, since the simulated lunar soil is generally loose, once collision with other devices or vibration during placement is large, the properties of the simulated lunar soil deviate from a predetermined value, thereby causing inaccurate evaluation of the erosion mechanism of the lunar soil.
