COMPOSITE DISK FOR SUPPORTING FAN BLADES

摘要

The composite support disc or ring (10) for a row of fan blades (62) in a bypass turbine engine is made up of plies of high strength fibers so oriented as to carry the loading developed on the ring (10) by the fan blades (62) and with the fan blades (62) mounted to minimize the loading on the composite disc (10). The orientation of the fibers are different in selected areas of the disc to provide a high strength disc (10) with a minimum weight.
