Lunar base construction.

摘要

The intent of this dissertation is to structure the problem of "How to build the lunar base?" in a logical, systematic, and quantitative manner. The primary goal is to develop a method for driving further research and development by identifying critical issues that may serve as a research agenda, based upon quantitative analyses. A technique is presented that can be used in studying lunar base construction operations and equipment selections. Uncertainty is used as a guide for quantitatively identifying areas in which further research represents substantial, potential savings in the construction effort. Generic tasks and their corresponding productivities are used to generate construction activities and schedules for the first eight years of lunar base development. Nine sets of lunar conceptually-designed construction equipment are investigated for constructing the lunar base as described in NASA's Office of Exploration, Exploration Studies Technical Report, FY 1989 Status (NASA-1 1989). A mathematical model is presented, the output of which is total, construction-related, Earth-launch mass. The two primary components of total, construction-related, launch mass are equipment launch mass and crew-consumables launch mass. The work is significant in that it demonstrates the usefulness of quantitative analysis for identifying research needs for lunar base construction and emphasizes construction task-productivities as an important and primary element of evaluating construction concepts and equipment. The Boles Lunar Excavator concept is suggested as a means of overcoming some of the fundamental difficulties involved in lunar excavation and leveling for construction and mining operations.
