WebbSince the propeller blade will be set at a given geometric pitch angle () the local velocity vector will create a flow angle of attack on the section. Lift and drag of the section can be calculated using standard 2-D aerofoil properties. (Note: change of reference line from chord to zero lift line). Webb31 jan. 2024 · We want to focus on the spin, what the axis is, and how that is related to the movement of the pitch. Even more specific, you can have two pitches with the same velocity and spin rate but have different movement profiles based on the axis of the ball. Below is a pitch with a “1:00” spin axis and a 95% spin efficiency, based on Rapsodo …
