Geared turbo fan theory
The geared turbofan is a type of turbofan aircraft engine, with a gearbox between the fan and the low pressure shaft to spin each at optimum angular velocities. The benefit of the design is lower fuel consumption and much quieter operation. The drawback is that it increases weight and adds complexity. See more In a conventional turbofan, a single shaft (the "low-pressure" or LP shaft) connects the fan, the low-pressure compressor and the low-pressure turbine (a second concentric shaft connects the high-pressure … See more • Garrett TFE731 • Lycoming ALF 502/LF 507 • Pratt & Whitney PW1000G • Rolls-Royce UltraFan See more • Ducted fan • Propfan Related lists • See more After considering a geared design, General Electric decided against it for its CFM LEAP due to weight and reliability concerns, … See more • Rolls-Royce/SNECMA M45SD, a derivative of Rolls-Royce/SNECMA M45H turbofan, designed to demonstrate ultra-quiet engine technologies, needed for STOL aircraft operating from city centre airports • IAE SuperFan, an IAE V2500 derivative proposed … See more WebAug 7, 2024 · [video & text: Rolls-Royce plc]Around the world in testing conditions: get an insight into our outstanding UltraFan technology, as it goes through its paces ...
