Compact - Additive Layer Manufactured Air Oil Heat Exchanger

ended

The C-ALM AOHE project will design, develop, manufacture and test a compact air-oil heat exchanger for next generation geared VHBR/UHBR turbofan engines. The work will include: • Design a C-ALM AOHE incorporating novel geometry and construction with step change technology attributes • Create a thermal model of the proposed design using computational techniques • Build a thermally representative C-ALM AOHE • Performance test the C-ALM AOHE concept and validate the thermal model • Refine the C-ALM AOHE design and build an optimised C-ALM AOHE • Test and validate the C-ALM AOHE in line with the Topic Manager's requirements The C-ALM AOHE project will deliver a fully validated air-oil heat exchanger to TR 6, MCRL4 and MRL6 with a heat load of 80kW and a dry weight of significantly less than 10kg that can directly flow into follow on flight demonstrator and NPI programmes.
