Keystone Helicopter is introducing its new Silencer airframe at Heli-Expo, along with expanded Rolls-Royce 250 and Honeywell LTS 101 engine services.

The Silencer uses an advanced carbon fiber skeletal structure that incorporates AC ductwork as structural cross members and attaches to the airframe with isolators. The outer framework supports the interior for improved rigidity and reduced vibration while permitting access for airframe inspections and allowing room for an acoustic blanket.
