Erickson Incorporated announced this week that the company has received FAA approval for composite main rotor blades for S-64 and CH-54 helicopters.
After many years of manufacturing metal blades, the company invested in the future of the S-64 by designing, certifying, and building composite main rotor blades that will bring many benefits. Erickson began the process of designing the new blades in 2008, working closely with the FAA and various industry partners. In 2013 they collaborated with Helicopter Transport Services (HTS), so the blades could be utilized on CH-54 rotorcraft as well.
To maintain close control of blade manufacture, Erickson built a composite manufacturing facility from scratch in 2015. After thousands of hours of design, testing, and analysis by their engineers and partners, the new composite main rotor blades are now approved by the FAA for the S-64E with an initial life that will increase as fatigue testing continues. Certification for the CH-54A is expected to follow quickly in the coming weeks, and certification for the S-64F and CH-54B should be received this summer.
In February Erickson announced the S-64F+ which will have composite main rotor blades, an enhanced cockpit and flight control system, an improved water cannon, and what the company calls a modern engine enhancing range and fuel efficiency.
