ABSTRACT:
An advanced composite blade construction for a helicopter rotor blade using for the most part fiber reinforced plastic materials in which the major assembly of blade elements is a single step co-cure operation and in which an integral spar/skin carries centrifugal, flapwise and chordwise loads and also incorporates redundant means to carry torsional loads and a honeycomb core carries shear and aerodynamic pressures loads.
