Cavity Purge Flows inside axial turbines

Oct 07, 2022

Turbomachinery in its various applications form the principal prime mover in the energy and aviation industries. Any improvement to this vast fleet of machines has the potential of significant impact on global emissions. Areas identified to benefit from continued research are the topics of flow mixing and cooling.
These are topics inherent in stationary gas turbines and jet engines due to the hot gas flows utilized. Cooling is achieved through injection of cold air in critical areas and thereby ensuring safe operation. The cooling however comes at a cost. On the cycle level this flow requires power to be compressed to the appropriate pressure, but does not contribute to the cycle output. In addition, the injection itself reduces the output power due to the losses associated with the mixing process. The study is centered to a turbine testing facility allowing detailed flow measurements in a rotating turbine stage under the influence of the cavity purge flow and also develop CFD models which can simulate the flow physics accurately.

EleFanT – Electric Fan Thruster

Oct 07, 2022

Under the project, which spans over 1.5 years, GKN Aerospace and KTH will together develop fan technology for smaller regional aircraft. The project will study aerodynamic design, performance, noise and manufacturing technology for a ducted fan powered by electricity, either from batteries, hydrogen fuel cells or even more conventional hybrid propulsion solutions.
The proposed propulsion solution with a ducted fan instead of a conventional propeller offers significant advantages in three main areas: safety, noise level and engine installation. By rapidly demonstrating fan technology for electric aviation, the EleFanT project will accelerate the pace of electric aviation development and position the participants for international aero-engine and aircraft development projects.
