Software to calculate the performances and to sort out the impeller.

Our rotation scheme
 

Watching with the air that come into the impeller
Rotation clockwise (P) e anticlockwise (A)

 

Our scheme of flow
 

FMV (flow engine-fan) the air crosses the control first, later the impeller

FVM (flow fan-engine) the air crosses the impeller first, later the control
 

Our way to change rotation angle

 
With insert 5° in 5°



Traditional system with graduated insert (B); it is necessary to disassemble impeller to change rotation angle.


 
With continuous bead



New solution: thread tag (A1) instead of the nut (A), no graduated insert (B1), thread bead (C). Enough to release the hubs for change the angle; useful mostly to make some tests.
