Beschreibung
Zusammenfassung:	The present invention relates to a cavitation free rotary mechanical device with improved output and, in particular, to a rotary mechanical device (such as a hydro turbine, marine propeller, etc) including a rotatable shaft and associated blades (or cups or vanes), the rotary mechanical device configured to introduce air at one or more areas of extremely low pressure force on the surface of, or at least in the proximity of, the rotatable blades (or cups or vanes) during rotation and thereby prevent cavitation effects that would otherwise be caused by the extremely low pressure forces acting on such surfaces during operation.
