https://en.wikipedia.org/wiki/Herbert_O._Fisher
....about halfway down the page:

Early tests with transonic compressibility.

"The desire to develop a propeller that maintained its efficiency at
transonic and supersonic speeds led the Curtiss-Wright Propeller
Division to design and test several different concepts, including a
thin, cuffed four-blade and a three-bladed "scimitar" design.
Utilizing a specially modified P-47D-30-RE on loan from the USAAF,[N
6] Fisher undertook over 100 high Mach number precision dives from
38,000 ft (11,582 m) at speeds from 500 mph (800 km/h) to 590 mph (950
km/h).[N 7] The typical flight began above 35,000 ft (10,668 m) when
Fisher would push over into a steep dive, allowing his airspeed to
build beyond 560 mph (900 km/h) (true airspeed).[21] He would then
execute a pullout at 18,000 ft (5,486 m), having to maintain an
exacting set altitude within plus or minus five ft.[9]"
