The fabrication methodology for a composite maia rotor blade for the YAH‐64 Advanced Attack helicopter (AAH) is presented. The design approach and criteria utilized in achieving a composite blade which is dynamically compatible with, and geometrically similar to, the AAH metal blade are discussed in detail. The material selection criteria and application to structural and non‐structural components are also discussed. Application of the wet filament winding co‐cure process selected as the method of facrication to achieve the structural and dynamic compatibility of the subject composite main rotor blade is the major thrust of this paper.
