Noise and vibration abatement system for the AW 139 helicopter

The new SILENS system, developed by SEI in collaboration with AgustaWestland, is made by a self-sustaining composite structure forming a sort of secluded shell fixed to the helicopter lower structure and isolated from the ceiling and the rest of the fuselage, thus dramatically attenuating transmission of noise and vibrations into the cabin.

While providing unrivalled isolation with respect to other noise abatement solutions, the SILENS balances design with sound engineering to produce the most comfortable alternative for the AW 139 passenger’s comfort, with negligible impacts on cabin dimensions and aircraft weight.

The result is an unequaled comfortable passenger cabin for the AW 139, with astonishing low noise and vibration levels, featuring a flexible, functional and very chic interior while meeting all the certification standards. The system has been approved by EASA under a SEI’s STC and is available for installation or retrofit on all AW 139 VIP helicopters equipped with hinged passenger doors.
