turbojet
Definition
turbojet (noun) 1. A type of jet engine: A gas turbine engine where a turbine-driven fan compresses air before it enters the combustion chamber, providing increased thrust. 2. An airplane powered by such an engine: An aircraft that is propelled by a turbojet engine.
Usage and Examples
- The modern turbojet is more efficient and powerful than early jet engine designs.
- The airline is updating its fleet with newer turbojets to reduce fuel consumption.
- That loud roar you hear during takeoff is from the aircraft's turbojets.
Advanced Usage
- Technical Context: In engineering, the term specifically distinguishes an engine where the air from the intake fan passes through the core (compressor, burner, turbine). This contrasts with a , where some air bypasses the core.
- Early commercial aircraft like the Boeing 707 used pure turbojet engines.
Variants and Related Words
- Turbojet engine (noun phrase): The full term for the engine itself.
- Fanjet (noun): A common synonym, though it can sometimes refer more broadly to turbofan engines.
- Turbofan (noun): A related, more modern engine type where a significant portion of air bypasses the engine core; it is generally more efficient than a pure turbojet.
- Jet engine (noun): The general category of engines that produce thrust by ejecting a high-speed jet of gas, which includes turbojets.
Synonyms
- Fanjet
- Jet engine (in a general sense)
- Gas turbine engine (in a general sense)
Notes on Meaning
The word "turbojet" can refer to the engine unit itself or, by common association, to an aircraft powered by such engines. The context usually makes the specific meaning clear.
Noun
-
a jet engine in which a fan driven by a turbine provides extra air to the burner and gives extra thrust
-
