Purpose and goal
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.
Expected effects and result
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.
Planned approach and implementation
The project starts May 7th 2025 until June 30th 2028 and the timeline is as follows: Aero design - Q2-3 2025. New PhD student onboarding and mechanical desing of ultra-short TRS - Q2 2025 - Q1 2026. Experimental campaign - Q1 2026 - Q4 2027. Synthesis of experiments and development of design tools - Q1 2027 - Q2 2028. Dissemination of results throught the whole project.
