Multi-scale methodology for the maturation of innovative acoustic solutions for aircraft engine noise
FY 2024-25
Summary
The airline industry has been working for several years to reduce aircraft noise, for the benefit of passengers and communities near airports. During takeoff and landing, the low-frequency, wide-band noise of new generation engines is difficult to control. Also, the emergence of futuristic means of transport intended to improve urban mobility, that is vertical take-off aircraft or drones, has led to the development of unducted rotor engines whose noise radiates into the cabin. Generally, the areas and space available for low frequency acoustic treatments are limited. In addition, treatments must respect structural and operating constraints.
This research program will propose disruptive acoustic technologies integrated into engines and into fuselage interior panels. It is structured around three objectives:
* develop a multi-scale research method to create effective acoustic materials from representative unit cells (micro) to complex acoustic systems operating in a realistic environment (macro);
* develop phenomenological models correlating the microstructure of unit cells to the mechanical properties of the acoustic material measured under conditions of use;
* develop robust and reliable manufacturing processes and deliver real functional prototypes; and
* assess the real impact of noise control measures on the environment.
This research program will train more than 39 highly qualified personnel (HQP) and will yield significant scientific and technological contributions the fields of noise control and advanced modeling and simulation. Partners SAE, FDC, SphèreCo and ADM will contribute to the creation of knowledge and translation into the design, optimization and manufacturing of acoustic materials. They will also contribute to Quebec's positioning as a world leader in the aeronautical industry.
