Hexcel says that its Acousti-Cap broadband sound-reducing honeycomb has successfully been used during a NASA-Boeing flight test on a B737 MAX test platform.

The material can attenuate a broader noise frequency range and has increased acoustic absorption due to the design of the overall inlet that reduces drag and improves noise attenuation, Hexcel says. This can enable engine designers to reduce the noise from takeoffs and landings yet without adding significant weight to the aircraft.

‘Hexcel has continued investing in the evolution of Acousti-Cap product technology to improve performance and reduce cost,’ said Imad Atallah, group product manager for honeycomb at Hexcel. ‘Collaboration with industry leaders, including NASA and Boeing, has been key to that development.’
