Hi,
I'm reading some material in relation to propeller design and don't understand the theory.
I don't understand is the vector V, why is it going from bottom to top? Shouldn't it be coming from the top of figure 1.8?
Same for 2 pi r n, shouldn't rotational wind be coming from right to left not right to left?
Figure 2-2 makes complete sense.
Also:
How does Figure 2-2 translate into figure 3.6? If you have a linear rotational wind and a constant forward wind, adding those two vectors together would result in a shift of the linear rotational wind vectors but not cause a curve (quadratic function) as seen in figure 3.5??? You're adding a fixed quantity to a linear function and getting a quadratic???
