Innovation Brings Clean to our Skies

GKN Aerospace engineers have successfully tested a new lightweight demonstrator of a Turbine Rear Structure (TRS) as part of the Clean Sky-2 Engines research Programme. The purpose of a TRS is to manage the flow from the engine’s low-pressure turbine and maximize the axial thrust. It is a key component in improving the efficiency of an aero-engine.

Innovative design and state-of-the-art manufacturing methods resulted in a shorter and lighter structure compared to a traditional TRS. This was achieved by using a novel metallic alloy with higher temperature capability, as well as both metal casting and 3D-printed technology. The optimized balance between aerodynamic performance, weight and mechanical properties demonstrates a significant (14%) weight reduction potential, contributing to lower carbon emissions of the engine.
