2. An aircraft in which a turbofan is used. In both senses also called fanjet.


1. (Aeronautics) Also called: high bypass ratio engine a type of by-pass engine in which a large fan driven by a turbine and housed in a short duct forces air rearwards around the exhaust gases in order to increase the propulsive thrust
2. (Aeronautics) an aircraft driven by one or more turbofans
3. (Aeronautics) the ducted fan in such an engine
Also called (for senses 1, 2): fanjet
