New Concepts for High Temperature Turbine Engine Oil Pumps



OBJECTIVE: Develop a novel strategy to increase the usable oil temperature of turbine engine oil pumps. Concepts focus to increase the usable temperature over conventional design to a temperature of 400-500 degrees F, while maintaining cold temperature requirements, -40 degrees F. The design should accommodate both MIL-PRF-7808 and MIL-PRF-23699 oil, and allocate the option of magnetic chip detectors and sensors. 

DESCRIPTION: Typical strategies for oil pumps will utilize oil supply pumping elements and air/oil scavenge elements. The oil pump design must also accommodate magnetic chip detectors, bypass valve and sensors. This SBIR topic seeks to explore new strategies/materials not currently utilized to increase the oil pump usable temperature to 400-500 degrees F, while maintaining a low temperature capability of -40 degrees F. A key focus would be a drop in replacement for legacy designs with significant usable temperature increase and no additional weight or complexity. A strong collaboration with the OEMs is highly recommended from Phase II of this program. 

PHASE I: Show the feasibility for a novel concept or new material for high temperature turbine engine oil pumps. Develop a design/test strategy for evaluating the ideas and identifying the key performance parameters necessary to document ability to perform on engine. Develop an initial transition and business plan. 

PHASE II: The methodology developed in Phase I should be validated for additional conditions approaching those found in practice with physical testing, and show feasible build processes and stable quality assurance processes. In the Phase II effort, steps should be taken to establish requirements for integration of the high temperature oil pump design into a standalone design tool that incorporates sufficient details to allow it to successfully predict increased performance. The work should be transitioned to interested OEMs. 

PHASE III: Future Phase III efforts should involve further commercialization of strategies developed for incorporation into elevated TRL demonstrations. These TRL demonstrations should focus on turbine engine lubrication system integration. Potential military application in NGAP, and a potential commercial application is the Boom Supersonic Transport XB-1 Aircraft for the SBIR/STTR technology.
