AeroThermals for Enhanced Engine Exit (AT3E)
Research Project, 2017
Purpose and goal
The project has investigated both aerodynamic performance and heat transfer in an aerodynamically optimized Ultra Efficient Turbine Rear Structure in the test rig at Chalmers University. Important flow features that affect the performance of the turbine structure have been studied including boundary layer laminar-turbulent transition, separation margins, and secondary flows. The heat transfer has been studied in less detail and will be studied with additional measurements for several configurations, with the aim to complement aerodynamic studies with heat transfer studies.
Expected results and effects
The project is expected to conduct the first detailed investigation of heat transfer under realistic conditions. The maturity of the project is at TRL 4 and with these additional tests is expected to advance to TRL 5. Heat transfer tests will focus on two configurations: one with engine mount recess and the other with welds. This will give an understanding of the thermal loads in critical areas of the component which are currently missing.
