Abstract : This paper contains the results of a development study on a spherical, hydrostatic, compliant bearing for a directional gyro. The concept of the rubber air bearing and its subsequent development is traced through its analytical analysis and experimental hardware fabrication to the test results. Use of a compliant material for one of the bearing surfaces, which would grip the rigid surface when unpressurized, constitutes the novel concept of self-caging. Included in this paper are the basic design curves developed for the compliant bearing. Use of these curves provides the bearing engineer with the basic tools necessary to design compliant air bearings. Unusual problems encountered in the fabrication and evaluation of rubber bearings are shown and discussed. Areas of further investigation are indicated which would enhance the rubber bearing development technologies. (Author)
