Green Regional Aircraft
On a global level, 45% of today’s flights are operated with regional aircraft, and in 2020 this figure is estimated to rise to around 50%.
The objective of the Green Regional Aircraft (GRA) ITD is to validate and demonstrate the technologies best fitting the pollution and noise reduction goals set for the regional aircraft that will enter the market in the 2020s.
The ITD will deliver:
- Low weight technical solutions using advanced structures and materials
- Configurations for low aerodynamic noise
- The optimised integration of technologies developed in other ITDs.
The activities of the GRA ITD are organised to:
Develop the most promising “mainstream” technologies (Low Weight and Low Noise Configurations) best fitting the requirement of greening future regional aircraft.
Integrate technical solutions, using a multidisciplinary approach, from mainstream technologies and from other technical domains of Clean Sky into the Demonstrators of the Green Regional Aircraft.
Use technology from several recent or on-going research programmes to constitute the significant background to the GRA ITD.
Demonstration
The technologies and the solutions developed and matured in the GRA ITD will be demonstrated to gather final confidence on their applicability to future aircraft programs.
Full scale advanced structural assemblies, low noise advanced aerodynamics, integration of advanced systems and avionics will be tested on ground and in flight as appropriate, along with large-scale wind tunnel tests of advanced aircraft configurations.
