turbofan
Học thuậtThân thiện
Definition
- Noun:
- A type of jet engine: A turbofan is a jet engine in which a large fan at the front, driven by a turbine, draws in air. Most of this air bypasses the engine core, providing quieter and more fuel-efficient thrust than a pure turbojet.
- An airplane using this engine: A turbofan can also refer to an airplane that is propelled by such an engine.
Usage Examples
- Noun (Engine):
- Modern commercial airliners are almost all powered by high-bypass turbofans.
- The key component of a turbofan is the large ducted fan at the front.
- Noun (Airplane):
- The airline added several new turbofans to its fleet for the long-haul routes.
Advanced Usage
- Technical Context: In engineering, the efficiency of a is often described by its "bypass ratio," which is the ratio of air that bypasses the engine core to the air that goes through it.
Variants and Related Words
- Fanjet: A synonym for a turbofan engine or an airplane equipped with one.
- Turbojet: A simpler type of jet engine without a large bypass fan, providing more thrust at high speeds but less efficiency.
- Turboprop: A turbine engine that drives a propeller, used for slower regional aircraft.
- High-bypass turbofan: The most common modern type, where a large majority of the intake air bypasses the core, optimizing for fuel efficiency and noise reduction.
Synonyms
- Fanjet (noun): A direct synonym for both the engine and the aircraft.
- Bypass engine (noun): A descriptive synonym highlighting its key technical feature.
Related Phrases
