Lift-to-drag ratio - Wikipedia

WebThe effects of lift and drag combine to form the ‘total resultant aerodynamic force’, in other words the result of adding these two forces together. Using positive pitch within certain limits it is possible for this combined force to be in front of the axis of rotation (as in the diagram) and it will tend to drive the rotor blade forwards.
