The DAAA (Aerodynamics, aeroelasticity, acoustics department) prepare technological responses for the benefit of industry to improve the Aerodynamics, Aeroelasticity and Acoustics performanceofaircraft, and address issues of competitiveness as well as societal, environmental and defence needs. This work opens up new paths of research and paves the way for the technologies of tomorrow
It interfers with the engines, affects the aerodynamic performanceof the aircraft, and causes deterioration of the sensors... The variant that causes most degradation ofaircraftperformance when the temperature is close to zero is called" the runback refreezing barrier"... Then there is glaze ice whereby local trickles of water form horns of ice thus lowering the aerodynamic performanceof the aircraft
To improve the performanceofaircraft and helicopter engines, the temperature needs to be increased. But then we come up against the limits of the materials used to manufacture the engine
