ABSTRACT:
The mounting assembly of a rotary wing aircraft is formed to include a ceal headpiece which operates to support the rotor blades of the aircraft, which blades are mounted to extend radially outwardly from the central headpiece. The headpiece includes rotor mounting supports having a bifurcated configuration consisting of two arms each having a flat, generally planar shape which extend at a right angle relative to the plane of the rotor. The headpiece may be formed of a pair of generally congruent plate members with an intermediate spacer member located therebetween, with the plate members and the spacer member being integrally joined together in a unitary structure made of composite fiber material.
