An extraordinary technological effort to define propulsion systems of the future that minimise environmental impact and energy consumption

Challenge/Domain
Challenge: 
Protecting the environment and the energy supply
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 dramatically reduce Exhaust emissions - NOx, CO, UHC and particulates
R&I needs: 
-Optimise exiting and explore new combustor architectures and injection system technologies in order minimise the gaseous pollutants and particulate emissions. -Physical modeling supported by combustor tests with non-intrusive mesurement and full characterisation of exhaust emissions.
Achievements
2020: 
* Low-Nox Injection System (Multi-Stage, Multi-point, ) : applicable to large OPR range & small size core engine and with Low Noise emissions * Lean Premixed Pre-vaporised (LPP) Injection System for direct and reverse flow combustors * Lean Combustion Ignitor : Laser * Reduced cooling : optimized design & new materials
2035: 
* New Combustion Architecture : Low-Nox Trapped Vortex combustor, * Lean Stabilized Combustion : Plasma injection * Low Particules Injection System Technologies
2050: 
* New Combustion Concepts : Flame Less combustion, * Interturbine burning, burning in vitiated air at high power
