About This File
Propeller design and aircraft performance for homebuilt experimental aircraft. Designs propeller automatically for best performance. Based on NACA/NASA wind tunnel test data for 2, 3, and 4 blade propellers. Computes pitch, diameter, blade chords and pitch angles. Also provides airfoil coordinates for Clark-Y and R.A.F.-6 airfoils at every desired blade radius. Gives block dimensions for carving any wooden propeller.
