Lord delivers Chinook IVCS to Boeing
Lord Corporation announced the delivery of the first production orders of its Improved Vibration Control Systems (IVCS) to Boeing for the CH-47 Chinook heavy-lift helicopter on 25 October.
Lord is supplying the IVCS system to Boeing under a contract signed in 2013 as a direct/drop-in replacement for the previously used passive tuned vibration absorber.
The system uses accelerometers to measure aircraft vibrations. The signals are delivered to a centralised computer, which processes them through a software algorithm that interprets the data and accordingly sends commands to force generators under the pilot seats. These force generators produce the appropriate amount of 'anti-vibration' to counter the progression of vibration from the main rotor, creating a more comfortable environment for the aircrew.
The IVCS technology aims to offer triple-digit weight reductions, and will be part of the baseline configuration from 2016 for the CH-47. It will be fielded by the CH-47F and the H-47 foreign military aircraft. The first production aircraft with IVCS is expected to be delivered in late 2016.
