Pratt & Whitney
Pratt & Whitney is an American aircraft engine manufacturer of products widely used in both civil and military aircraft. As one of the "big three" aero-engine manufacturers, it competes with General Electric and Rolls-Royce, although it has also formed joint ventures with both of these companies. In addition to aircraft engines, Pratt & Whitney manufactures gas turbines for industrial and power generation, marine turbines, and rocket engines. The company over 38,500 employees support more than 9,000 customers in 180 countries around the world.

Evolution of the Pratt & Whitney eagle logos
In 1925, Frederick Rentschler approached the Pratt & Whitney Machine Tool Company in Hartford, Connecticut for funding 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. This was the beginning of the Pratt & Whitney Aircraft Company. Pratt & Whitney's first engine, the 425 horsepower (317 kW) R-1340 Wasp, was completed on Christmas Eve 1925. On its third test run it easily passed the Navy qualification test in March 1926; by October, the Navy had ordered 200. The Wasp exhibited performance and reliability that revolutionized American aviation. The R-1340 powered the aircraft of Wiley Post, Amelia Earhart, and many other record flights.
The R-1340 was followed by another very successful engine, the R-985 Wasp Junior. Both engines are still in use in agricultural aircraft around the world and produce more power than their original design criteria. Replacement parts for both engines are still in production and it is theoretically possible to assemble a new engine from the parts.
In 1929, Rentschler ended his association with Pratt & Whitney Machine Tool and formed United Aircraft and Transport Corporation, the predecessor to United Technologies Corporation. His agreement allowed him to carry the Pratt & Whitney 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 and also has plants in Columbus, Georgia; Middletown, Connecticut; Dallas, Texas; Cheshire, Connecticut; West Palm Beach, Florida; Toronto, Ontario; and North Berwick, Maine.
Between 1967 and 1971, Pratt & Whitney turbine engines were used in American Championship Car Racing and Formula One. Parnelli Jones's entry in the 1967 Indianapolis 500 dominated the race until a small part failed four laps from the finish. The following year, Team Lotus entered a trio of 56s at Indianapolis. Two of the cars qualified fastest and second fastest, but all three retired from the race. Turbine cars were deemed illegal before the following year's race, so Lotus chief Colin Chapman developed the car for use in Formula One and an updated 56B competed in half a dozen Formula One races in 1971.
Pratt & Whitney is a business unit of industrial conglomerate United Technologies, making it a sister company to Sikorsky Aircraft, Hamilton Sundstrand, Otis Elevator Company, UTC Fire & Security and refrigeration giant Carrier Corporation. It is also involved in two major joint ventures, the Engine Alliance with GE which manufactures engines for the Airbus A380, and International Aero Engines company with Rolls-Royce, MTU Aero Engines, and the Japanese Aero Engines Corporation which manufactures engines for the Airbus A320 and the McDonnell Douglas MD-90...(and so on)
