Curtiss XP-42

History of the Curtis XP-42

The Curtiss XP-42 is an evolution of the Curtiss P-36 Eagle model, although it shares some initial external similarities with Curtiss' most famous aircraft, the P-40 Warhawk. Later in its development, the XP-42 will undergo a number of changes that compare it to its P-36 roots. The system was converted from a P-36A, serial number 38-004, and was tested in a series of tests designed to reduce the drag characteristics of radial piston engines.

As a result, this P-36A features a redesigned nose and an all-new engine that drives the three-bladed propeller.

This aircraft features air intakes under the engines, while carburetor blades are mounted on top. In an interesting design feature, a long shaft was designed to properly reach and drive the propeller system.

The resulting aircraft proved to be faster than the P-36A, but also had engine cooling problems, severe vibration problems inherent in the propeller shaft system, and the XP-42 would never be faster than the P-40. As a result, the XP-42 gave way to the P-40 Warhawk family of aircraft, which would secure available Army production orders and become one of the classic American fighter jets of the time.

Only one P-36A was converted to the XP-42. The system is powered by a Pratt & Whitney R-1830 radial series engine producing an impressive 1,050 horsepower. The system was operated by a crew, and the entire project officially ended in 1947, after which the aircraft was scrapped for parts.
