Lord Rotor Damper Certified
An elastomeric main rotor damper developed by Lord Corp. has gained U.S. Federal Aviation Administration certification for use on the Enstrom 480 light turbine helicopter. The damper has been incorporated into new production models and is available for retrofit into existing helicopters in the field. Designed to replace the 480’s original hydraulic dampers, the Lord design is claimed to provide better ride and handling qualities and a marked reduction in vibration in flight. Elastomeric dampers incorporate special polymers that are designed to have the elastic qualities of natural rubber.
