Centrifugal force

March 2, 2009 - 6:33am

Lord and Sikorsky are developing a lightweight, self-contained hub-mounted vibration system (HMVS) for the Connecticut manufacturer’s future medium and heavy-lift helicopters as part of Sikorsky’s “High Performance, Low Vibration and Low Noise Enabling Technologies Program” in cooperation with the U.S. Army. The HMVS system features motorized imbalanced rotors that rotate at the blade-pass frequency to create centrifugal forces.
