Abstract
A fan blade assembly using air bearing features to reduce frictional losses, reduce physical wear and tear, and allow for faster acceleration of the fan blade within the assembly is disclosed. A fan blade housing incorporates inlets for pressurized air which create a pressurized area between the fan blade and the housing. The pressurized area functions as an air bearing interface and the fan blade is kept at a controlled distance from the fan blade housing as it spins. In an alternate embodiment, the fan blade assembly has pass-through inlets which use air pressure generated by the fan itself as it spins to provide the pressurized air for the pressurized area.
Claims20
A fan blade assembly comprising:
- a) a fan blade, the fan blade having an outer surface;
- b) a fan housing, the fan housing having an inner surface, the inner surface in operational proximity to the outer surface such that the fan blade can rotate within the fan housing;
- c) one or more air inlets in the outer surface which communicate with an interface zone, the interface zone comprising a space between the inner surface and the outer surface;
- and
- d) a source of pressurized air operably communicating with the air inlets, such that the source of pressurized air can create a positive pressure in the interface zone.
