In addition to engine parts, GMS provides customers with fleet management and customized maintenance service programs. GMS received its first part certification in July 2007, when the Federal Aviation Administration (FAA) granted Parts Manufacturing Approval (PMA) certification for the GMS high-pressure turbine (HPT) shroud for the CFM56-3 engine.In March 2008, the FAA certified the GMS fan and booster with a Supplemental Type Certificate (STC) with FAA Chapter 5 life limits equal to the original type certificate holder.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, and marine turbines.
Pratt & Whitney's Military Engines power 27 air forces around the globe, with nearly 11,000 military engines in service with 23 customers in 22 nations.
The Wasp exhibited performance and reliability that revolutionized American aviation. Both engines are still in use in agricultural aircraft around the world and produce more power than their original design criteria.
George Mead soon led the next step in the field of large, state-of-the-art, air-cooled, radial aircraft engines (which the Wasp dominated) when Pratt & Whitney released its R-1690 Hornet. In 1929, Rentschler ended his association with Pratt & Whitney Machine Tool and merged Pratt & Whitney Aircraft with Boeing and other companies to form the United Aircraft and Transport Corporation.
As of 2017, the company reported having 38,737 His social network included Edward Deeds, another prominent Ohioan of the early aviation industry, and Frederick's brother Gordon Rentschler, both of whom were on the board of Niles Bement Pond, then one of the largest machine tool corporations in the world.
Frederick Rentschler approached these men as he sought capital and assets for his new venture. Rentschler persuaded the board of Niles Bement Pond that their Pratt & Whitney Machine Tool (P&WMT) subsidiary of Hartford, Connecticut, should provide the funding and location to build a new aircraft engine being developed by Rentschler, George J.
