Aircraft engines, considered unreliable during the first 20 years of aviation due to their need for liquid-cooling, heavy weight and other inconsistencies, were given a revolutionary boost with the development of Pratt & Whitney’s R-1340 Wasp Radial Engine in 1925.

Rapid development of aircraft design in the 1930s required many related innovations, including propeller design. The hydromatic propeller by Hamilton Standard marked a significant advance over the counterweight-type, controllable pitch propeller. The first test flight of the prototype took place in 1938: the public demonstration was made by a United Air Lines DC-3 over New York City on April 6, 1938. It played a distinguished role in allied combat aircraft in World War II.
