The Green Regional Aircraft, one of the six Clean Sky platforms, led by Alenia Aeronautica, the ITD member, involves 32 European partners among engine manufacturers, system engineering companies, research centres, universities, small and medium enterprises.
The future green regional aircraft will meet demanding weight reduction, energy and aerodynamics efficiency, an high level of operative performance, in order to be compliant regards to pollutant emissions and noise generation levels. To achieve these so challenging results, the aircraft will be entirely revisited in all of its aspects.
The research activity carried out by GLAMOUR project is part of the GRA2 domain, which will evaluate the effects of drag reduction of the aircraft with a view to reducing consumption and external noise. Drag in particular will be reduced, by using Natural Laminar Flow (NLF), that will be integrated with specific innovative anti-ice and high lift systems able to alleviate well-known drawback of NLF technologies. Flow and load control systems activated by electric fly-by-wire commands will be also investigated both for drag and weight reductions. In order to reduce external noise and drag the study will deal mostly with approaching and landing phase, improving high lift device (HLD) technologies. Gears will also require further aerodynamic optimization, with respect to past approaches, in order to reduce the turbulences they generate and consequently reduce noise.
