Abstract
A carrier ring for a large diameter propeller system fabricated from a composite material having metallic blade mounting insert members in which are fastened roots of the propeller blades. The carrier ring has an annular ring member formed of a composite material which defines a plurality of radially extending openings, in which openings metallic blade mounting insert members are attached. The blade mounting insert members are retained in assembled relationship with the composite annular ring member by one or more fastening belts which extend around the circumference of the annular ring member in one or more grooves defined by the blade mounting inserts. The fastening belts may be formed by a plurality of turns of a fibrous filament, such as carbon filaments, so as to provide the necessary strength to retain the metallic blade mounting inserts in the composite annular ring member.
