WebAnswer (1 of 2): Limited top speed. A high-bypass engine works great at the speeds of a typical airliner, but if you want to go faster you need to use something more “turbojet-like”, so you reduce the bypass ratio. (a Turbojet can be thought of as a “zero-bypass engine”.) This is why fighters use...

WebAn ultra high bypass ratio turbofan engine includes a variable pitch fan, a low pressure turbine, a reduction gearbox, and a plurality of outlet guide vanes. The ultra high bypass ratio turbofan engine has a bypass ratio between about 18 and about 40. The variable pitch fan and the low pressure turbine are coupled together by the reduction gearbox. WebUn turboréacteur à double flux (dit en anglais turbofan) est un moteur à réaction dérivé du turboréacteur. Il s’en distingue essentiellement par le fait que la poussée est obtenue non seulement par l’éjection de gaz chauds, mais aussi par un flux d’air froid — ce dernier flux peut même fournir davantage de force (mesurée en kilonewtons ) que le flux chaud.
