Domain category: 
Technology
Enabler
Enabler: 
An extraordinary technological effort to define propulsion systems of the future that minimise environmental impact and energy consumption
Cluster of enablers: 
An extraordinary technological effort to define the air vehicles of the future that minimise environmental impact and energy consumption
Capability
Capability: 
To dramatically reduce the environmental impact and fuel consumption of aero gas turbines
Sub capability: 
To Improve the Propulsive Efficiency of aero gas turbine propulsion systems
R&I needs: 
- Exploit extreme by-pass ratio engine benefit by ultimate improvement of aerodynamic efficiency, PPS drag, light weight structure - Develop High Fidelity CFD methods and components tests rigs able to demonstrate and validate the propulsive efficiency improvement
Achievements
2020: 
* UHBR ducted turbofans, BPR>12 * Variable Fan Nozzle Concepts * Demonstrated disruptive configurations such as Open Rotor propulsor * Advanced single propeller turboprop * Optimisation of the Integration of the PPS : Improved Nacelle : Slim, Short, Laminar Variable intakes, which allow shorter, smaller diameter inlets, with retained low speed / crosswind capacity, reduce noise
2035: 
* Dispruptive configurations : High power efficient and compact gearboxes UHBR ducted turbofans, single or contrarotative, BPR>16 Variable pitch FAN, variable guide vanes, variable geometry nozzle/nacelle * Optimisation of the Integration of the PPS : Light reverse adapted to UHBR Very short & compact nacelle with composite materials
2050:
