Evaluation of Gas Lubricated Hydrodynamic Bearings in a Gas Turbine Environment.

AD744844

Publication Date	1972
Personal Author	Swenson, K. R.; Hughes, N. M.; Heuer, D. F.
Page Count	58
Abstract	The report contains a summary of the design analysis, development testing, and demonstration testing performed to demonstrate the feasibility of using gas lubricated hydrodynamic bearings in a gas turbine environment. The gas generator portion of the jet fuel starter used on the A7D aircraft was modified to incorporate compliant-foil gas bearings and subjected to varied demonstration test. In addition, engine starts were made under conditions which simulated normal starting gear loads. Results of the testing were very satisfactory. It is concluded that gas lubricated bearings can be used in a gas turbine application and further testing is encouraged. (Author)
