Lunar soil simulant by low gravity for drilling

Abstract

The invention discloses a lunar soil simulant by low gravity for drilling. The method comprises: firstly, selecting rocks for preparing the lunar soil simulant as raw materials for preparation according to the chemical components and the rock components of the actual lunar soil; drying and dehumidifying the raw materials, pulverizing, sieving to obtain pulverized samples with different particle sizes, selecting additive raw materials, and sieving to obtain the additive raw materials with different particle sizes; and then selecting the pulverized samples and the additive raw materials according to the required particle sizes of the lunar soil simulant, and configuring the pulverized samples and the additive raw materials to obtain a sample and the density of pulverized samples and the additive raw material; finally, calculating the mass ratio of each component of the pulverized samples and the additive raw materials according to the low gravity for drilling, mixing the pulverized samples and the additive raw materials to obtain the lunar soil simulant.

Description

technical field [0001] The invention relates to the field of deep space exploration, in particular to a low-gravity simulated lunar soil for drilling. Background technique [0002] In the mission of sampling the environment of extraterrestrial celestial bodies such as the moon and Mars, the gravity environment is less than 1g. Due to the differences with the earth environment, it is often necessary to compensate for the influence of gravity environment differences on the sampling task in ground verification tests. Current low-gravity compensation methods generally include heavy object suspension, balloon suspension, air flotation platform, deep well drop method and aircraft flying parabola method, etc. Due to the discrete nature of the lunar soil, methods such as hanging heavy objects, hanging balloons, and air flotation platforms cannot be used; while the deep well drop method and the aircraft flying parabola method allow too short working time to meet the needs of long-te...
