Capability
Capability: 
To dramatically reduce the environmental impact and fuel consumption of aero gas turbines
Sub capability: 
To improve the thermodynamic efficiency of aero gas tubine engines
R&I needs: 
-Maximise engine thermal efficiency through increased cycle pressures and temperatures, whilst minimising cooling air requirements -Maximise component efficiencies through high fidelity CFD methods, component rig testing to demonstrate and validate the improvements, and modelling of multiple components (up to the entire powerplant) as a single model. -Minimise internal sealing flows and parasitic losses to maximise thermal efficiency
