    Wood wasp inspired space and earth drill

    In this chapter, we explain why the low gravity encountered on Mars or on the Moon and the low mass of the probes, landers and rovers that carry drilling devices limit classical drilling techniques. Novel boring solutions optimised in mass and power consumption are thus needed for space applications. Biologists have identified the wood wasp, an insect that is capable of "drilling" into wood to lay its eggs. A low mass and low power system, like an insect, capable of drilling into wood is of the highest interest for planetary drilling and terrestrial drilling alike. The general working principle of the wood wasp drill ("dual reciprocating drilling") will be exposed and the potential benefits of imitating the wood wasp for planetary drilling will be highlighted. Since the nature of wood is highly fibrous but the nature of extraterrestrial and terrestrial soils are not, it is necessary to adapt the wood wasp ovipositor to our target soils. A test bench to evaluate the influence of the different geometries and operational parameters was produced and is presented here. The dual reciprocating drilling experimental results obtained on this test bench are also highlighted. They should lead to a new and enhanced model and comprehension of dual-reciprocating-drilling

Annotated by John W. Carven, C.M. After more than 40 years devoted to the preparation of the English edition of the correspondence, conferences, and documents pertaining to Saint Vincent de Paul, this cumulative Index marks the culmination of the entire series. To facilitate research, each entry in the alphabetical index is accompanied by a brief annotation of how it is used on the page or pages given. Place names are printed in italics, and cross references are supplied, where judged appropriate. Many variations in spelling occur. Following the Index are two Appendixes: Biblical References and Errata.https://via.library.depaul.edu/coste_en/1019/thumbnail.jp
