SIkorsky completes testing of mounted vibration system

October 15, 2010  By Carey Fredericks

Oct. 15, 2010, Stratford, Conn. - Sikorsky Innovations has completed rig testing of a Hub Mounted Vibration Suppression system (HMVS), designed to eliminate vibration and deliver a smoother helicopter ride. The effort is jointly funded by Sikorsky and the Aviation Applied Technology Directorate (AATD).

"HMVS represents a significant improvement in the control of vibration at its source with less weight than conventional vibration treatments," said Jim Kagdis, program manager for Sikorsky Advanced Programs. "Combined with our active flap technology, this makes the opportunity for a jet-smooth ride a practical reality. Our plan is to install and test flight this vital technology on a Sikorsky helicopter in the next 12 months. We expect to drive this technology into all our products once its commercialization is complete."”

"Vibration, even at the low levels Sikorsky has been able to achieve, takes a toll on crew and passengers as well as the aircraft," said Mark Miller, Vice President, Research & Engineering. "With the HMVS breakthrough technology, occupants will experience less fatigue and enhanced safety. In addition, operating costs will decrease because equipment will last longer in a virtually zero-vibration environment."”

The key development team member for the project is the LORD Corporation of Cary, North Carolina.
