Abstract
An apparatus that is rotatable around a first axis to propel an intercepted fluid in a radial direction. The apparatus has a support, a first blade assembly, and a second blade assembly. The first blade assembly has a first blade with a first substantially flat surface residing in a first plane that is substantially parallel to the first axis. The second blade assembly has second and third blades respectively having second and third substantially flat surfaces residing respectively in second and third planes, each extending substantially parallel to the first axis. A single piece defines at least a part of the second and third substantially flat surfaces. The second blade assembly is separate from the first blade assembly and joined to the support so that the blades cooperatively propel intercepted fluid in a radial direction.
