Proof of concept. Prop will work at mach tip speed, and fly at mach speed. Look up the Thunderscreech.
And it flew faster than what most sites post.

Also the feather weight solar powered aerodyne by Paul McCready went 7 x faster than on sea level at 100 000 feet altitude.

I wish there was the finances so us like minded folks could work together and make this happen.
