Definition
A "turbofan engine" is a type of jet engine that combines a turbine with a large fan, making it more efficient and quieter. A large fan at the front pulls air in; some goes through the core engine, and some bypasses it. đ Think of it as a hybrid between a turbojet and a propeller engine. Unlike turbojets, turbofans bypass air around the core. This increases fuel efficiency and reduces noise. Turbofan engines are commonly used in most modern commercial airliners. âī¸
