Bearing Analytical Software Development and Validation

ABSTRACT: This proposal describes an analytical software approach to model rolling element bearings for gas turbines and similar drive systems. Detailed approaches for modeling bearing material fatigue life, oil churning, and tribology are presented. The resulting analytical bearing code will enable gas turbine engineers and designers to better assess engine lubrication system thermal loads and size bearings for adequate life early in the engine design process. The proposal contains a plan to commercialize the bearing analytical code for gas turbine engines. BENEFIT: Improved analytical software will reduce design issues in development and provide more reliable engines in production. The software will also be beneficial to other high end bearing applications such as rocket turbopumps and satellites.
