Abstract:

Efforts continued on the development of gas lubricated journal and thrust bearings for use in blower motors. Start-stop testing on a prototype motor-blower unit demonstrated the ability of the gas bearing design to withstand 66,600 start-stop cycles without harm to the perform ance of the bearing. Continuous operation of the prototype unit for 1192 hours produced very little wear on the thrust bearing surfaces, indicating their ability to meet the 20,000 hour design life requirement of this development program. Three units made to final design configuration successfully completed vibration and salt spray testing with no detrimental effects on bearing performance. All testing to date indicates that the final design units will meet all performance and qualification test require ments. Work was completed on the section of a gas bearing design manual dealing with the pre diction of half-frequency whirl, and work con tinues on the final section of the manual, which concerns the design of gas thrust bearings.
