Foil bearing Research for Aerospace Applications
Abstract
The University of Texas at Arlington (UTA) and Rolls-Royce/LibertyWorks (R-R/LW) will work to improve the development process and tools used to design radial and thrust foil air bearings for use in missile/attritible gas turbine engines. Improvement of the current development process will reduce the developmental costs and improve the performance of future Navy weapon systems. The intent of the effort is to develop scaling laws that are applicable to this engine class based upon existing successful applications of foil bearings. Additionally, improved analytical methods will be developed to more accurately model the performance and heat generation of thrust foil air bearings. A baseline foil air bearing rotor support design will be completed and tested for gas turbine engine at the lower end of the anticipated size range to gain insights and lessons learned on how to improve the scaling tools and analytical methods. Once the baseline rotor rig testing is successfully completed, the developed scaling laws and analytical methods will be updated and applied to a second design representing the upper end of the size class to demonstrate the newly developed scaling.
