Why still no dive acceleration difference?

[Crumpp]

those supersonic propellers max tip Mach is more than 1.3 while WWII p47 max tip Mach is below 1.15. quite different story.

Come on man....

You understand the basic's of rotational mechanic's right?

On any radius of the circle, the point closest to the origin travels at a slower velocity than a point distal to the origin.

That is why as a generality, a smaller disc is better for Vmax performance.
