Looking at my ally prop, the leading edge is generally round. I usually file the back of the leading edge to give a more hydro-dynamic profile to the leading edge/surface.
Flying back home yesterday and looking at the airplanes wing profile had me wondering would a rounded leading edge create less drag than a knife edge?
If a knife edge is better, should it be bevelled on the leading edge, trailling edge, or equally to each edge?
When supplied new they are square on the leading edge??
I suspect the rounded wing profile is to cope with the varying angles of attack, but how much would the angle of attack change with a prop?
