Abstract:

An investigation of air-lubricated foil bearing technology for application in advanced propulsion and power systems was performed. The work conducted under the program comprised a establishment and documentation of the state-of-the-art of foil bearings, b development of analytical tools and design guides to permit calculation of the performance of bending-dominated foil bearings, c investigation of potential substrate and coating materials, as well as conduct of start-stop and high speed rub tests with two air-lubricated foil bearings at 1000 deg F, d preparation of a layout drawing of a dynamic simulator test vehicle based upon an advanced engine 1980 or later time frame in the 1000 to 3000 pounds thrust class, as well as a description of the test facility requirements, e description of the technology segments of air-lubricated foil bearings that need to be advanced to meet the requirements of the advanced engine application, and definition of the parameters for a long range test effort.
