A Lubrication System for Space Vehicles 640007

The conditions of space environment, especially high vacuum, and the high degree of reliability required are two important aspects of the problem of lubrication for space vehicles. Experiments have been made using conventional designs to achieve high reliability, and a narrow gap seal with a calculated oil loss instead of a rubbing contact seal. Two systems are evolved from theoretical considerations derived from the kinetic theory of gases. The experiments have validated the usefulness of this approach.
