Clean Sky Info Day – Toulouse 1rst February 2011
GRA Overview
GRA program was launched on 1st September 2008 (GRA Kick-Off: October, 7th- 8th
2008), and will allow future regional aircraft to obtain weight reduction, aerodynamics
efficiency and an higher level of operative performance w.r.t. “year 2000” technology
level.
In order to achieve these so challenging results, the aircraft will be entirely revisited in
all of its aspects. In fact GRA consists of five technological domains: Low Weight
Configuration (LWC), Low Noise Configuration (LNC), All Electric Aircraft (AEA), Mission
& Trajectory Management (MTM) and New Configuration (NC).

All Electrical Aircraft
Main objectives of AEA is to demonstrate the feasibility of on-board systems
new technologies and architectures enabling the application of the AllElectric approach for a Regional airplane which aims:
 to completely delete the Pneumatic and Hydraulic power
 to enhance the Electrical power
 to apply new technologies which optimise the energy usage (Electrical and
Thermal Energy Management)
 thus contributing to Specific Fuel Consumption reduction (estimated
around 2-3%, based on previous preliminary studies)
Main function/systems affected by AEA concept:
 Electrical Power Generation & Distribution
 Power electronics
 Electrical engine starting
 Electrically powered cooling/heating and compression (ECS, Ice Protection, equipment
cooling)

New Configurations
 Next generation of Regional A/C will be
strongly affected by the “Green
Requirements”;
 New aircraft, systems architectures and
advanced configurations might be
necessary to accomplishing such
requirements;
 Moreover integration of new technologies,
propulsion in particular, will affect the
overall A/C sizing;
 Careful assessment is required to evaluate
eco benefits, and overall competitivity as
well;


 Advanced technologies will be assessed through a cost effective mix of
ground and flight tests covering the technical solutions of integration of
airframe, systems and engines at aircraft level.
 In this respect, full scale structural ground tests, large scale
aerodynamic and aero-acoustics wind tunnel tests, and flight simulators
have been considered.
With reference to the generic regional aircraft type, the following Demonstrators
will be produced:
