Oil Transfer Bearing for Advanced Pitch Change Mechanism

Topic description

Specific Challenge:

Future aeroengine architectures are likely to feature main power gearbox, as power transfer element between low pressure turbine and low pressure compressor, and may require performance pitch control mechanism. Both features, that may coexist or be implemented separately, are based on high energy oil transfers to rotating parts. One key feature to concept competitiveness is the availability of an advanced Oil Transfer Bearing ensuring this transmission function, and featuring reduced mass, enhanced stiffness, improved maintainability, high accuracy and increased actuation capability. The project intends to identify most relevant concept; to design it from concept to detailed design; to manufacture, assemble and test it in representative testing conditions (vibration, endurance, performance, actuation; etc).
