WebAug 2, 2012 · It's easier to compute thrust first, then convert that into prop wash speed. Typically, prop blades aren't symmetrical, and their step angle varies along the length of the blade. But suppose we take your simple approximation. In that case, you should probably treat each blade as a thin airfoil, and that's relatively easy to solve. http://www.grenadabluewatersailing.com/boat-handling-rudders-propellers/
