dominates the shape of the a versus C curve, the expected variation of a with C 

 should be of the form 



a = kC.

The constant k is governed by the local geometric and boundary layer character- 

 istic at the foil tip. This relationship has been used successfully in the current 

 study and also proved convenient for comparing the TVC inception merits of the var- 

 ious concepts.
