Available in PDF, EPUB and Kindle. Book excerpt: Research was concerned with the feasibility of drilling a hole on the moon. The preliminary feasibility study showed that of every known proven drilling method and many untried methods, percussion drilling will be the most suitable for Lunar drilling, where the weight and space requirements are limited for the first drillequipped Lunar craft. Study indicated that the mechanical simplicity of the rotary system should give it a reliability advantage for small dimeter (1/2 in.) holes which are less than 5 feet deep. Conversely, deeper holes and holes of 3/4 to 4 in. diameter can best be made by a percussor. For heavier space craft of the future where deep holes larger than 4 in. diameter are desirable, it is almost certain that rotary drilling with rolling cutter bits will have many advantages.

Book excerpt: A short study has been conducted to determine the feasibility of a device for producing a hole in the lunar surface. The study includes both a literature survey and an experimental program. The experimental program investigated both rotary and percussive drilling with low thrust and no flushing fluid. Rotary drilling does not appear feasible due to the lack of sufficient thrust for effective cutting. Percussive drilling, on the other hand, appears to be quite acceptable for producing the required hole and is capable of reasonable drilling rates when the cuttings are removed from the hole mechanically.
