20130136613, May 30, 2013

Filed:

Nov 25, 2012

Appl. No.:

13/684554

Inventors:

David Silvano - Lehigh Acres FL, US

International Classification:

F01D 5/00
F01D 5/22
F01D 5/02
F01D 5/34

US Classification:

416227 R

Abstract:

A medium mover/reactionary surface can be used a propeller, impeller, wind generator blade, mixer and the like. The blade design has a shape that pulls against itself under load to maintain its intended shape. The blade design includes one or more generally flat or contoured strip-like sections. These strip-like sections can be attached at their centers to a hub and at the tips to create rake and pitch.

International Classification:

US Classification:

416227R

Abstract:

A propeller/impeller blade adapted to propel a vehicle or other device, create a vacuum, or move a medium, comprising a generally flat strip-like member having first and second opposite ends joined together to form a pair of contiguous loops with a generally figure eight configuration about its longitudinal axis. The upper and lower surfaces of the loops are continuous throughout its figure eight configuration and structured so that if one were to trace along the upper surface longitudinally in a single direction, they will return to the same location on the upper surface from where they began without traversing the lower surface. In use, the pair of loops are mounted on the shaft of the desired device so that each loop is disposed symmetrically about the longitudinal axis of the shaft and the longitudinal axis of the pair of loops is disposed in perpendicular relation to the longitudinal axis of the shaft.

US Classification:

416227R

Abstract:

A three dimensional figure eight propeller/impeller blade apparatus is provided which may be used to propel a vehicle, power a shaft, create a vacuum, or move a medium. The blade apparatus is made from an elongated strip of generally flat material. In one embodiment, the ends of the flat strip of material are joined together to form two loops having an overall three dimensional figure eight configuration. In forming the loops, the upper and lower surfaces of the flat strip of material are continuously maintained relative to each other.
