high-bypass turbofan engine

Aviation; Aeronautics

A turbofan engine in which the fan moves more than four times as much air as is moved by the core engine compressor. This type of engine is said to have a bypass ratio of more than 4:1.

low-bypass engine

Aviation; Aeronautics

A turbofan engine whose bypass ratio is less than 2:1.

medium-bypass turbofan engine

Aviation; Aeronautics

A turbofan engine with a bypass ratio of between 2:1 and 4:1. This means that the fan moves two to four times as much air as the core engine.

A turbofan engine with some of its low-pressure compressor blades extended. These extended blades act as a fan and force air around the outside of the gas-generator portion of the engine. Most modern ...

aft-fan engine

Aviation; Aeronautics

A turbofan engine with the fan constructed as an extension of some of the turbine blades, rather than as an extension of the compressor blades. This fan pulls large volumes of air around the outside ...

vectored-thrust engine

Aviation; Aeronautics
