Capability
Capability: 
To dramatically reduce the environmental impact and fuel consumption of aero gas turbines
Sub capability: 
To dramatically reduce the environmental impact and energy consumption of aircraft propulsion systems through better Powerplant system integration
R&I needs: 
- Develop new technologies at powerplant system integration level allowing fuel burn, emissions and weight decrease as well as improving adverse conditions operation (Ice, rain, sand) - Develop multi-dimensional optimisation capability
Achievements
2020: 
* Efficient & high power density gearboxes & transmissions with minimum vibration * Advanced air/air and air/oil sealing systems * Advanced tip clearance control systems: closed loop, adaptive (to minimise deterioration) * More electric, high power density & integrated engine systems: * Integrated, adaptive thermal management system * Improved structural integration of engine, nacelle & TRU for performance, weight and noise * Design and modelling capability for improved rain/hail/ice/sand&dust protection * Intelligent & integrated controls, sensors & actuation for improved deterioration, operability and prognostics * Optimized by-pass system (engine, Nacelle, and TRU) and improved structural integration for performances, noise and weight
2035:
