Boeing 797 blended wing fsx planes11/13/2022 ![]() ![]() Although they do not currently make a geared turbofan, CFM International, a joint venture between GE Aviation and Safran Aircraft Engines of France, is also considered a likely candidate to build a new engine. Pratt & Whitney is researching the possibility of upgrading a geared turbofan engine it already makes, the PW1000G, while Rolls-Royce is arguing for a geared turbofan currently in development known as the UltraFan. ![]() Pratt & Whitney and Rolls-Royce have both offered engines for consideration. The versatility provides greater optimization of engine speed during different parts of flight.ĭiagram of a geared turbofan. Geared turbofans are aircraft engines that achieve greater efficiency by placing a gearbox in between the fan and the turbine assembly so they can rotate at different velocities. The NMA's composite fuselage may require a new factory.īoeing hasn't been exactly clear about what it means when it refers to the NMA fuselage as composite with a "hybrid cross-section." However, the Seattle Times reports that Boeing vice president Mike Delaney used the term to mean a fuselage with elements of both a narrow-body and a wide-body-though the plane will likely have two aisles-rather than "hybrid" meaning it would use both composite and metallic materials.įor the new aircraft's engines, Boeing is looking for a geared turbofan. Boeing also just built a billion-dollar factory in Everett, Washington, to bake the epoxy-infused carbon fiber wings of the 777X. The composite fuselage sections of the 787 Dreamliner are manufactured in North Charleston, South Carolina Wichita, Kansas and Nagoya, Japan. ![]() The company predicts a market for more than 4,000 of these planes.īuilding such a jet will require Boeing to expand its carbon fiber composite manufacturing. It would then build the aircraft components in 2020-1, assemble the new plane in 2023, and fly it for the first time in 2024, with the new aircraft ultimately entering service in 2025. Boeing wants a plane to fly routes in that gap around 5,000 nmi-say, New York to Moscow, or even further.īoeing unveiled a timetable in which design work would happen in late 2018 through 2020. The new airliner would fill a gap between the narrow-body 737 MAX and wide-body 787 Dreamliner, which have ranges as high as 3,800 nmi and over 8,000 nmi, respectively. The NMA is to be a twin-aisle plane with a capacity for 220 to 270 passengers and a range of 5,200 nautical miles, according to Aviation Week. However, Boeing's official project name (for now) is simply New Midsize Airplane (NMA). The airliner has been called the 797 at the show. This week at the 2017 Paris Air Show, the company discussed some design details for a new passenger plane, revealing that the aircraft will have a composite fuselage with a "hybrid cross-section" and "fifth-generation" composite wings. ![]()
