Compact - Additive Layer Manufactured Air Oil Heat Exchanger


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.
