Study of Thermal and Aerodynamic Performances of Light and short turbinE Rear structure (STAPLER)

Research Project, 2025 – 2028

The purpose is to deliver a novel TRS design and AM will be included to enable a flexible design. A new PhD student will be hired that will master numerical design tools at GKN Aerospace and the capabilities of the LPT-OGV rig at Chalmers University. The project will validate unexplored design spaces with experimental data while eliminating typical risks of a new design. The project will support GKNs participation in future engine programs and solve the urgent need for CO2 reduction.

It is expected to gain more understanding on how an aggressive ultra short aero design of TRS behaves both from an aerodynamic and heat transfer point of view. In this way it will be possible to have the validation and de-risking needed for a most probable next generation product development in collaboration with the most influent OEMs in the aerospace industry. Together with this the tools usually adopted at GKN for aero design and thermal evaluation will be updated according to the findings.
