IVCS qualified for Chinook

8th September 2016 - 12:30 GMT | by The Shephard News Team


LORD Corporation has received product qualification for its Improved Vibration Control System (IVCS) for the Boeing CH-47 Chinook heavy-lift helicopter, the company announced on 6 September.

With qualification approval granted by the US Army Aviation Engineering Directorate, product deliveries for incorporation into the Boeing CH-47F have now begun.

The IVCS system has been developed under a contract with Boeing signed in 2013 as a direct/drop-in replacement for the previously used passive tuned vibration absorber.

The system controls steady state and transient vibration. The technology uses accelerometers that measure aircraft vibration levels. A centralised computer processes these signals through a software algorithm, interpreting the data and sending commands to force generators located under the pilot seats. These force generators create ‘anti-vibration’ that stops the progression of vibration from the main rotor, and creates a more comfortable vibration environment for the aircrew. 

The IVCS is installed using existing mounts on the Chinook aircraft.
