Turbofan

noun

Noun

1
A turbojet engine having a (usually ducted) fan that drives a stream of air that partly bypasses the turbojet portion; in high-bypass-ratio types, most of the thrust comes from the bypass portion rather than the turbojet portion, and this can be thought of in simplistic terms as that the turbojet portion drives the fan and the fan propels the aircraft.
"Turbofans are always multispool engines."
2
a jet engine in which a fan driven by a turbine provides extra air to the burner and gives extra thrust wordnet
3
An aircraft with such engines.
4
an airplane propelled by a fanjet engine wordnet

From turbo- + fan.
