SABRE, adptive blades for next generation rotorcrafts<img alt="" src="" style="BORDER:0px solid;" />, adptive blades for next generation rotorcrafts<p style="text-align:justify;">​The European Project of SABRE (Shape Adaptive Blades for Rotorcraft Efficiency) ended with important results, obtained over 4 years, with focus on the development of innovative morphing technologies, oriented to helicopter blades. The advantages in terms of fuel consumption, CO2 and NOx emissions and noise radiation for this type of vehicles will support Europe for the challenging goals of a sustainable aero-transportation and a worldwide competitive helicopter market.<br></p><p style="text-align:justify;">Funded by the European Program Horizon 2020, the Project saw the participation of CIRA (under the coordination of the Adaptive Structures Laboratory), DLR, TU-Delft, TU-Munchen, University of Swansea, with the leadership of the University of Bristol and the support of the renowned industries of Airbus Helicopters and Leonardo Helicopters.</p><p style="text-align:justify;">CIRA, in particular, through the laboratories of Adaptive Structures (S. Ameduri, M. Ciminello, A. Concilio, I. Dimino, B. Galasso) and Virtual Realty (M. Guida), developed the “core" of the technology, that is to say, an original blade torsion system made of Shape Memory Alloy (SMA), assuring the functionality and the absorption of the loads, while the laboratories of Environmental Impact and Flight Mechanics (M. Barbarino, L. Federico, A. Sollazzo) and of Fluid Mechanics (A. Visingardi, P. Vitagliano) addressed predictive analyses on the aeroacoustic impact due to the twist of the blade.</p><p style="text-align:justify;">Mention must also be made to the support for the characterization of the shape memory alloys (Structures and Materials laboratory: P. Caramuta, A. Ferrigno, A. Vigliotti) and to the realization of additive printing components (Space Qualification Laboratory: G. Bruno).</p><p style="text-align:justify;">Within the Project, two demonstrators of adaptive blade were realized that, after exhaustive tests addressed in the wind tunnel plant of University of Bristol and in the whirl tower facility of DLR, clearly proved the aerodynamic effectiveness of the concept and its working capability in representative environment. The high innovation level jointly to the strategic impact of the achieved results led also to a patent application on the architecture developed by CIRA.</p><p style="text-align:justify;">Also encouraged by the positive feedback of the European Officer that tracked and evaluated the Project, the Consortium is already working for the submission of a new proposal that continues and further enhances the legacy of SABRE.​​<br></p><p style="text-align:justify;"> <br> <iframe width="560" height="315" src="" title="YouTube video player" frameborder="0"></iframe> </p>2021-06-21T22:00:00Z
