Сверхзвуковой истребитель P-47

Тут некоторые товрищи пытались со мною спорить по поводу сверхзвука на П-47.

Вот вам доказательства! Получите! С графиком, и даже со сверхзвуковым пропеллером!!!
Все как я писал!
М 0,83 - посмотрите в моих предыдущих постах, я определил предел в 0.8-0.85.

Случайно, копаясь в сети в поиске графиков скороподъемности Бф-109 Г-2, я нашел доказательства своим предположениям о скорости П-47 в пике.
Вот они.

After the war, the development of propellers did not cease. Even with the introduction of turbojet powered aircraft, propeller design evolved. The desire to develop a propeller that maintained its efficiency at transonic speeds led the Curtiss Propeller Division to design and test several different concepts. Herb Fisher was the logical choice to fly the test aircraft. Curtiss was able to obtain a P-47D-30-RE from the Air Corps. Fitted with one of several different “supersonic” propellers, Fisher undertook a long and risky flight test program that incorporated high Mach dives from high altitudes. Typically, Fisher would climb above 35,000 ft. He would then push over into a steep dive, allowing his airspeed to build beyond 560 mph (true airspeed). He would then execute a pullout at 18,000 ft. Several of these dives resulted in speeds of Mach .83. However, that was as fast as the P-47 could go.
