Hello
Does anyone know where the prop pitch angle is measured? Is it the AoA of the prop tip, or 0.5 of the radius? I mean due to the twist the Blade has many AoA (standing aircraft).
The problem is that some aircraft have a angle bandwith of +15 - +90°. But with +15° the prop is stalled for takeoff right? Btw, is the prop of a Cessna with fixed prop stalled for takeoff?
On the other hand, when +15° refer to 0.5 of the radius, the outer section could produce lift. Thatīs why i ask
Thank you
