A manual for the design of hydrodynamic plain cylindrical journal and thrust bearings, in cluded as part II of this report, has been com pleted, employing the latest information and techniques in this field. Special emphasis has been placed upon the prediction of half-frequency whirl by use of what is considered an improved analysis technique. To confirm the validity of the design methods, numerous tests were conducted on an instrumented rig, and a small 20 cfm blower-motor assembly meeting the performance and environmental requirements of MIL-B-21399 were developed. The results of rig tests and quali fication tests of the blower-motor assembly are summarized. Author
