The Ducommun AeroStructures (DAS) business of Ducommun has been awarded a $7 million contract plus follow-on options by Carson Helicopters to build the new Carson composite main rotor blade for use on all S-61 helicopters.
The work will be performed at the DAS facility in Monrovia, CA with deliveries commencing in 2003.
Carson believes that the new composite main rotor blades will allow S-61 Helicopters to lift an additional 2,000 pounds and fly 15 knots faster than existing metal main rotor blades. In addition to the performance improvements, the new blades are expected to have twice the service life.
The blades are currently in the final stages of FAA Certification and are being offered as a retrofit product to commercial and military operators world-wide. There are 5 blades per helicopter and there are currently over 600 S-61s available for retrofit.
DAS’s Monrovia facility has built main rotor blades for over 25 years and is currently producing the Boeing AH-64 Apache rotor blades and has made rotor blades for Bell Helicopter’s Model 47, UH-1 Huey, and Model 206 JetRanger aircraft.
