What was the fastest propeller airplane in the USA in World War II?

The fastest propeller driven US aircraft of the war that saw service in combat was the P-47M Thunderbolt. Another answer stated that the XP-47J achieved over 500 mph in testing but only one of these was ever built.

What is the fastest manned aircraft ever built?

North American X-15
Number 1: North American X-15 This aircraft has the current world record for the fastest manned aircraft. Its maximum speed was Mach 6.70 (about 7,200 km/h) which it attained on the 3rd of October 1967 thanks to its pilot William J. “Pete” Knight.

Why do propeller blades have to be twisted?

The tip of a propeller blade travels faster than the hub. Therefore, it is necessary for the blade to be twisted so as to maintain a uniform angle of attack over the whole of the blade. There have been efforts to develop propellers and propfans for aircraft at high subsonic speeds.

What kind of planes were used in WW2?

The Museum’s collection of 30 World War II-era American military aircraft ranges from propeller-driven trainers, fighters, flying boats, and bombers to the nation’s first generation of jet-powered fighters to take to the air.

What kind of wood is used to make propellers?

Mahogany was the wood preferred for propellers through World War I, but wartime shortages encouraged use of walnut, oak, cherry and ash. Alberto Santos Dumont was another early pioneer, having designed propellers before the Wright Brothers for his airships.

What is the purpose of feathering a propeller?

Feathering. On single-engined aircraft, whether a powered glider or turbine-powered aircraft, the effect is to increase the gliding distance. On a multi-engine aircraft, feathering the propeller on an inoperative engine reduces drag, and helps the aircraft maintain speed and altitude with the operative engines.
