The present invention relates in general to the field of fluid reaction surfaces, and more specifically, to a fluid-foil impeller and method of use. One aspect of the fluid-foil impeller utilizes a plurality of fluid-foil discs that may be of uniform and/or variable thickness and configured to rotate rapidly in series to produce propulsion. Each fluid-foil disc comprises a leading edge, a trailing edge, a chord and a fixed pitch. The fluid-foil impeller may further include a standard or Venturi shroud that is designed to encompass the plurality of fluid-foil discs. The plurality of fluid-foil discs are configured to act in cooperation with the shroud to reduce losses incurred from turbulence and the conversion of mechanical work to fluid movement. Fluid may be acted upon by the plurality of fluid-foil discs and/or shroud, singly or in an array. A purpose of the invention is to provide a fluid-foil impeller and method of use that reduces harmful cavitation effects typically encountered by traditional propeller blades when operating at high revolutions per minute. An additional purpose of the invention is to provide a fluid-foil impeller that may be used efficiently and safely in a variety of industrial applications that requires successful propulsion a fluid.

A tray-type fan impeller structure includes a plate body annularly disposed around a hub. The plate body has a connection side connected with the hub and a free side extending in a direction away from the hub. Multiple boss bodies are arranged on a top face or the top face and a bottom face of the plate body at intervals.

The prior art has used pitched blades attached to a stationary motor, normally electric. to move air within the confines of a structure or room. The preferred invention incorporates a series of solid discs. The discs are affixed to a stationary electric motor and thus rotate around a central axis. The discs are equally spaced and centrally perforated in a manner that will allow air to flow in high volumes through the perforations and pass along the discs thus exiting symmetrically between each disc perpendicularly to the flow of air that is at its entrance. Due to the less restrictive or low pressure air entrance as well as the correct vertical disc spacing a corresponding increase in the laminar flow is realized. This feature of the preferred invention allows for operation at a rotational speed that practical for use as a ceiling fan.

A convector includes a stator made up of an array of fixed, parallel, equally spaced, equally thick, thermally conductive plates attached to a relatively thick thermally conductive plate. Convectors are provided with a rotor that is made up of an array of flat, rotatable, parallel, equally spaced, equally thick discs. The discs of the rotor are placed between the plates of the stator at relatively close proximity from the walls of the stator plates. Furthermore, the discs are keyed or held in place with the help of spacers and compression nuts to a hollow or a solid shaft. A clearance aperture, circular in shape, is provided on the stator plates. The shaft is held in place at both ends by roller bearings that provide the means for the shaft to rotate. To impart rotational motion to the rotor, the shaft is attached to an external device such as a motor.

A centrifugal pump for conveying a fluid, includes a pump housing, a rotor configured to convey the fluid disposed within the housing; and a stator which, together with the rotor, forms an electromagnetic rotary drive configured to rotate the rotor about an axial direction.
