Aircraft Prop Selection

Is there a calculation for selecting a three bladed prop to replace a 2 bladed prop
For instance..... 11x6 two blade prop change to a 6" three bladed prop to allow better ground clearance....Warren

    Add to my enquiry above. Is it legitimate to calculate the air volume for one turn of the 11"x6" prop and then recalculate the pitch of a 3 blade 6" prop because it is delivering an extra 50% air voume?.
    Easier still.... Who can tell me what 3 blade 6" prop will do the job from their own experience?
