Abstract
This invention relates to an aerodynamic blade assembly and method by which the blade is formed in a single cure cycle. A foam core having an aerodynamic shape is provided on which an inner spar wrap member, an upper spar pack member, a lower spar pack member, a lower outer spar wrap member, an upper outer spar wrap member, a leading edge block and a trailing edge wedge are laid-up from fiber-reinforced composite material. The total lay-up assembly with the core is placed in a mold tool and the tool heated to thereby cure and structuralize the total lay-up assembly to form the blade.
