摘要： A heat dissipating fan includes an impeller which has a hub extended forward from a rear wall. The hub has a plurality of first tenons formed at the front rim and a plurality of spaced slots. The spaced slots form a plurality of radial lugs such that the hub becomes elastic. The rotor of the fan is placed in the hub quickly and securely to complete the fan assembly. The impeller further has an annular sleeve which has a plurality of second tenons. Each second tenon is bordered by a pair of second slots at two sides. The motor shell may engage with the inner circumference of the sleeve and is held securely by the second tenons.

摘要： An exemplary embodiment of the invention is a spinner for a front end of a fan assembly of a gas turbine engine. The spinner includes a single piece substantially conically shaped hollow body circumscribed about a centerline extending aftwardly from a tip to an axially aft spinner end. A plurality of bolt holes extend axially parallel to the centerline through the hollow body at an axial location between the tip and the aft spinner end. The hollow body may include a forward conical section extending aftwardly from the tip to a transition section, an aft conical section extending aftwardly from the transition section to the aft spinner end, and the bolt holes are axially located in the transition section. An aft spinner flange attached to the axially aft spinner end includes a plurality of flange lightening holes axially disposed through the aft spinner flange and the flange lightening holes.

摘要： Increased impact resistance capability is achieved in a cost and weight efficient manner by providing a spinner made of a 3-D orthogonal woven composite material. The spinner defines a generally conical shell having a plurality of axial rib stiffeners and at least one circumferential rib stiffener integrally formed thereon. The combination of the integral rib stiffeners with the 3-D orthogonal woven composite material results in a substantially greater torsional stiffness. The use of the 3-D orthogonal woven composite material also eliminates delamination found in laminated composite spinners.
