PRATT AND WHITNEY

Pratt & Whitney is an American aircraft engine manufacturer whose engines power nearly half of the world's commercial fleet.In addition to aircraft engines, Pratt & Whitney manufactures fixed gas turbines for industry and power generation, marine turbines, railway locomotive engines, and rocket engines.Their powerful aero engines are used in some of the state of the art combat aircrafts like F-15 , F-16 ,the F/A-22 Raptor and F-35 Joint Strike Fighter.They also make gas turbines used to generate electricity . Pratt & Whitney Canada is the world's leading producer of engines for corporate jets, commuter aircraft and helicopters.The Pratt & Whitney Company was founded in 1860 by Francis Pratt and Amos Whitney, with headquarters in Hartford, Connecticut. The company manufactured machine tools, tools for the makers of sewing machines, and gun-making machinery for use by the Union Army during the American Civil War.In 1925 retired Captain Frederick Brant Rentschler who was assigned to oversee production of aircraft engines for the U.S. Army during the first world war approached Pratt & Whitney looking for funds and a location to build his new aircraft engine. Pratt & Whitney loaned him $250,000, the use of the Pratt & Whitney name, and space in their building.They started research to make aircraft engines with the guidance of chief engineer Andrew Wilgoos .In December 1925 Pratt & Whitney's first engine, the Wasp,came out of factory. Wasp passed the Navy qualification test in March 1926, and by October the Navy had ordered 200 engines.In 1929, Frederick Rentschler ended his association with Pratt & Whitney Machine Tool and formed United Aircraft and Transport Corporation, the predecessor to today's United Technologies. His agreement allowed Rentschler to carry the name with him to his new corporation.On August 2, 2005, Pratt & Whitney acquired the space propulsion company Rocketdyne from Boeing and renamed the company Pratt & Whitney Rocketdyne, Inc.
Pratt & Whitney is headquartered in East Hartford, Connecticut.
