LORD Receives Final Qualification on Vibration Control System

By S.L. Fuller | September 9, 2016

Steady state and transient vibration in the Boeing H-47 Chinook is now more controllable after the final product qualification of LORD Corp.’s patented Improved Vibration Control System (IVCS). This IVCS technology has a triple-digit weight-savings benefit, creating performance buy-back for operators. 

LORD Defense Business Manager Stuart Hartwell told R&WI product deliveries began in May, and the first aircraft off the line with the system installed is planned for delivery to the U.S. Army in early October. This will be followed by retrofit opportunities of Special Operations MH-47Gs, fielded CH-47Fs and Foreign Military Sales H-47s in 2017.

The system uses accelerometers that measure vibration levels and a centralized computer process that sends commands to force generators located under the pilot’s seat. This counteracts the aircraft vibration, creating a more comfortable environment.

The IVCS is a direct/drop-in replacement for its predecessor — heavy passive-tuned vibration absorbers — also located under the pilot’s seat. It’s made for easy installment, using mounts that already exist on Chinook aircraft.

This upgrade has come to fruition after 12 yr of development.
