With a duration of three and a half years, this" Swept Wing Ice Accretion Characterization and Aerodynamics Research" cooperation is aimed at understanding and modelling the deterioration of aircraft aerodynamicperformance due to ice build-up on the wings. The programme envisages a parametric study, test campaigns at Glenn (IRT) and at ONERA (F1), and simulations
At Modane-Avrieux in Savoy, a French aeronautics and space research and technology center where ONERA's very large wind tunnels are located, aircraft manufacturers from around the world come to test the aerodynamicperformance of their future aircraft. The tests performed there allow the uncertainty before the first flight to be reduced, thereby minimizing technical and industrial risks, which is a fundamental aspect for manufacturers in an increasingly competitive context
It interfers with the engines, affects the aerodynamicperformance of the aircraft, and causes deterioration of the sensors... Then there is glaze ice whereby local trickles of water form horns of ice thus lowering the aerodynamicperformance of the aircraft
