The Performance of Two Boeing-GM Wheels (GM VII and GM VIII) for the Manned Lunar Rover Vehicle,

摘要

Two candidate wheels for the Boeing-GM Manned Lunar Rover Vehicle, one fabric-covered and one constructed of open-wire mesh, were tested for mobility performance in a fine sand. Four levels of sand strength, representing cohesion values ranging from zero to 0.16 psi, were used in the tests. The cohesional and frictional properties of the sand spanned a range that is believed to include the probable range of lunar soil properties.
