Lubrication and cooling of UAV and attritable engine bearings can be a challenge when a recirculating lubrication system is removed from the system to reduce weight and cost.  The demand on these high-speed bearings becomes a challenge from a lubrication and cooling perspective.  Single-source lubrication is possible to design into a system to achieve this goal.  The key to successful design involves having the right testing, simulation, and analysis tools to find a successful solution.  This proposal provides an opportunity to expand the capability of bearing software, single contact software, and test data to assist in the design of engine bearing systems that need to perform in marginal lubrication and loss-of-lube scenarios.
