Increased Oil Pump Housing Temperature Capability

Triton Systems, Inc. proposes to develop a novel strategy to increase the usable oil temperature of turbine engine oil pumps using advanced aluminum casting alloys recently developed by the Department of Energy and reinforced aluminum technology previously developed by Triton. This will enable oil pump housings with usable operating temperatures in the range of 400-500 degrees F, while maintaining cold temperature requirements. The design will be compatible with both MIL-PRF-7808 and MIL-PRF-23699 oil and be a drop-in replacement for legacy designs with no additional weight or complexity. Our technical approach was previously demonstrated in a Navy SBIR Phase I/II/II.5 program to improve the temperature capability of turbine engine fuel pumps to a range of 300-350 degrees F. The technology reached TRL-4 by the conclusion of that effort. The proposed work builds on the legacy of the prior effort and offers a well-defined path to transition and insertion into an Air Force or other DoD program.
