For such an aircraft the fan design must, in addition to delivering low cruise fuel burn, enable low jet and fan source noise during takeoff. This requires the fan to be operating at low pressure ratio and high … how cats eat miceThe turbofan was invented to improve the fuel consumption of the turbojet. It would do this by increasing the mass and lowering the speed of the propelling jet compared to that of the turbojet. This would be done mechanically by adding a ducted fan rather than using viscous forces by adding an ejector, as first envisaged by Whittle. how cats get fip

"WebThe fan in a high-bypass turbofan is much larger to force a large volume of air through the ducts. These can generate more thrust, are better in fuel efficiency and are less noisy than the other engines. (Yoon J. 2001) The three major companies to introduce turbofan engines were General Electric, Rolls Royce and Pratt & Whitney. " - High bypass fan

WebThe increasing trend toward high-bypass-ratio turbofan engines has resulted in larger diameter fan cases. For example, the former GE 5:3 bypass ratio fan cases CF6-80C2 accounted for about 20% of the total engine weight, whereas the more recent 9:5 bypass ratio GEnx-1B represents a weight ratio of 33%. The use of PMCs can reduce the weight … WebSo upon deploying the thrust reversers, the air that has already produced a forward thrust on the fan blades now moves back through the bypass duct to strike the thrust reverser, thus redirecting the air forward by creating another action-reaction pair to slow the aircraft.
