Claim 5:
6. An airfoil operably coupled to a rotor and configured to rotate about a rotational axis, the airfoil comprising:
an outer wall defining a pressure side and a suction side extending in a chord-wise direction between a leading edge to a trailing edge and extending in a span-wise direction between a root and a tip to define a span (S);
an axial chord length (Cax) extending between the leading edge and the trailing edge in an axial direction with respect to the rotational axis; and
an aspect ratio (AR) of the airfoil is determined by:, C
    ax
   
   S
  
  ;
 

wherein the aspect ratio (AR) is greater than or equal to 2 and less than or equal to 6 (2<AR<6); and
wherein βin is constant along the span from the root to the tip, or βout is constant along the span from the root to the tip.
