Fig. 3 - Application of simultaneous thrust and 

 power identity criteria. See text 



however, this possibility does not exist, because of the asymmetric position of 

 the propeller with respect to the hull. 



The application of the thrust and power identity criteria of analysis allows 

 one to point out, and to evaluate the intensity of, the rotating inflow component 

 and therefore to have a more complete knowledge of the action which the hull 

 and its appendages exercise on the propeller performance.
