Lunar drill and test apparatus
The design of an experimental lunar drill and a facility to test the drill under simulated lunar conditions is described. The drill utilizes a polycrystalline diamond compact drag bit and an auger to mechanically remove cuttings from the hole. The drill will be tested in a vacuum chamber and powered through a vacuum seal by a drive mechanism located above the chamber. A general description of the design is provided followed by a detailed description and analysis of each component. Recommendations for the further development of the design are included.
