    摘要: An engine cooling fan system including a hub disc about which first and/or second pluralities of elongated fan blades characterized by a first and second respective pitch angles may be fastened. Each respective fan blade further comprises a hub-engaging portion, a twisted transition portion and an air-engaging portion. Each fan blade is formed from a composite material having a thermoset resin matrix phase and an evenly dispersed continuous fiber reinforcement phase.
