Problems solved by technology

This increases the load weight and volume of the planetary lander on the one hand, and limits the sampling efficiency on the other hand.
In addition, limited by the volume and power of the planetary lander, the lubrication and heat dissipation conditions of the drilling and sampling device of the planetary lander are poor, which further makes its adaptability to the complex planetary soil environment relatively weak

Abstract

The invention provides a multi-power-based space drilling device. The multi-power-based space drilling device comprises a drill bit arranged at the tail end of the space drilling device, an impact tunneling module, a rotary driving module and a control module. Wherein the impact tunneling module can hammer a drill bit, and the rotary driving module can drive the drill bit to rotate; and the control module can drive the impact tunneling module and / or the rotation driving module according to the current soil property.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a multi-power-based space drilling device and method. Background technique [0002] In lunar exploration missions or other planetary exploration missions in the future, drilling and sampling planetary soil is a very important mission goal. In the process of deep soil sampling, a special drilling sampling device is required to carry out the task of drilling and sampling the planetary soil within the reach of the lander. The drilling sampling device can be regarded as the core payload of planetary landers such as lunar exploration vehicles. [0003] Traditional drilling sampling devices can be divided into two types: drilling scheme and percussion scheme. The drilling scheme drives the bit to drill planetary soil through the motor and reducer, which has continuous excavation efficiency and position maintenance function, but it cannot effectively excavate when encountering a ha...
