Abstract: | In this paper, we consider a drilling method, which might prove useful both for applications on the Moon and for drilling
on Mars, Venus, or other planetary surfaces. It is based on the use of a cold gas flow for pumping fine-grained debris particles
out of the borehole, after they have been pulverized by the bore crown. We present a basic design and demonstrate by a hydrodynamic
calculation that such a system should work effectively even on an airless body like the Moon, where the driver gas has to
be provided from the associated lander or rover, which acts as the bore platform. |
