Composite main rotor blades for the new Erickson rotorcraft

After many years of manufacturing metal blades, Erickson has invested in the future of the S-64 rotorcraft by designing, certifying, and building composite main rotor blades that will bring many dramatic benefits

Erickson Incorporated, the leading operator, maintainer, and manufacturer of utility aircraft, announced FAA approval of its next-generation composite main
rotor blades.

After many years of manufacturing metal blades, Erickson has invested in the future of the S-64 rotorcraft by designing, certifying, and building composite main rotor blades that will bring many dramatic benefits.

Erickson began the process of designing the new blades in 2008, working closely with the FAA and various industry partners. In 2013 Erickson 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 Erickson’s 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 is expected this summer.
