Here is my question:
To my understanding aerofoils on an airplane air flow moves (horizontally) in the same direction as the motion of the aircraft; the aero foil then creates a pressure difference and an unbalanced force and lift is generated. Rowing blade manufacturers throughout their literature (see link below) talk about lift and angle of attack etc. What I do not understand is that how can you have lift when the direction of motion (the path the blade goes through the water) is largely perpendicular to the leading edge of the blade? Or is the flow that generates lift simply a function of the horizontal component of the water that flows over the blade. Any insight (or things to further research) and how one could being to optimize a blade would be greatly appreciated.
Thanks so much
