Definition

1. Noun:
   • A type of jet engine: A fan-jet is a jet engine where a large fan at the front, powered by a turbine, compresses air. Some of this air goes into the core for combustion (the burner), while the rest bypasses the core to provide additional thrust directly. This design makes it more efficient and quieter than older turbojet engines.
   • An airplane using this engine: A fan-jet is also an airplane that is propelled by one or more fanjet engines.

Examples of Usage

• Noun (Engine):
  • The new aircraft model features a more efficient fan-jet that reduces fuel consumption.
  • Modern commercial airliners are almost exclusively powered by fan-jet engines.
• Noun (Airplane):
  • The private fan-jet landed smoothly on the runway.
  • Their fleet consists of several long-range fan-jets.

Advanced Usage

• The term is often used interchangeably with turbofan, which is the more precise technical term for this engine type. The size of the bypass airflow (the air that goes around the core) is a key characteristic, leading to terms like high-bypass turbofan.

Variants and Related Words

• Turbofan (n): The full technical term for a fan-jet engine.
• Fanjet (n): A common alternative spelling, written as one word.
• Bypass ratio (n): A technical measure describing how much air bypasses the engine core versus going through it; central to design.
• Turbojet (n): An older, simpler type of jet engine without a large bypass fan, often contrasted with the .

Synonyms

• Turbofan (n): The direct synonym for the engine type.
• Jet engine (n): A broader category that includes the .

Related Phrases

• High-bypass turbofan: A common type of engine used on most large passenger aircraft, where most of the thrust comes from the fan's bypass air.
• Fan blade (n): A key component of the engine.

Noun

1. a jet engine in which a fan driven by a turbine provides extra air to the burner and gives extra thrust
2. an airplane propelled by a fanjet engine
