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.
“Silencer provides significant noise suppression inside the cabin and improved structural integrity with no loss in fuel efficiency,” explained Jim Munda, recently appointed Keystone vice president of engineering.
Keystone has a Sikorsky S-76 equipped with the Silencer on display in Booth No. 3063 that includes design panels that detach for maintenance access and sealed, edged cutouts for gaspers, lights and switch panels.
Keystone is also talking to customers about its expansion of accessory capabilities on the Rolls-Royce and Honeywell engines.
According to Ralph Kunz, Keystone vice president of MRO, adding accessory capabilities has allowed the company to offer a wider range of products on the R-R 250 engine, while supporting the LTS 101.
The Engine Services Division, which is an authorized maintenance center for Rolls-Royce 250 series engines, recently moved into a 52,000-sq-ft facility in Coatesville, Pa., that is equipped with a test stand and SOA test cell.
“We’ll be closing on some major contracts this year,” Kunz said. “Adding accessories allows us to do more for our customers, which makes us the logical single-source provider for engines.”
