geared turbofan jet engine from pratt & whitney
Pratt & Whitney PW1000G The Pratt & Whitney PW1000G is a high-bypass geared turbofan engine family, currently selected as the exclusive engine for the Bombardier CSeries, Mitsubishi Regional Jet (MRJ), and Embraer's second generation E-Jets, and as an option on the Irkut MC-21 and Airbus A320neo. The project was previously known as the Geared Turbofan (GTF), and originally the Advanced Technology Fan Integrator (ATFI). The engine is expected to deliver reductions in fuel use and ground noise when used in next-generation aircraft. The PW1000G engine first entered commercial use in January 2016 with Lufthansa's first commercial Airbus A320neo flight.[3]
V-twin engine Gottlieb Daimler built a V-twin engine in 1889. It was used as a stationary powerplant and to power boats.[1] It was also used in Daimler's second automobile, the 1889 Stahlradwagen ("steel-wheeled car").[2] The engine was also manufactured under licence in France by Panhard et Levassor.[3]
