1. A single stage turbo apparatus comprising:
- a common hub to support two or more rows of matching sets of rotating rotor blades, with attachment provision to facilitate the connection to a rotating shaft, and two or more rows of matching rotating blades configured in such a manner so that they allow a small portion of the high energy fluid from a leading blade to be directed behind a chaser blade for the purposes of boundary layer control.

Abstract
The present invention relates to an improved apparatus used for moving gases or air in a single stage for the purposes of either causing a vacuum upstream as in vacuum pumps or high-pressure downstream as in industrial blowers, turbochargers for automotive engines, ducted fan propulsion devices, and compressors for gas turbines. In this improved concept, two matching sets of rotor vanes are paired, rotating in the same direction, without a stator between them, having continuous and progressive pitch angles, the same number of blades, and designed to complement each other. Therefore, the turbo apparatus can yield extreme high-pressure ratios at high flow rates.
