Definition
- Noun:
- A type of aircraft engine, or an airplane powered by such an engine, where a gas turbine (turbojet) drives a propeller mounted on the front of the engine. This design combines aspects of a jet engine and a traditional propeller.
Usage
- The term "propjet" is a technical or informal term for a turboprop aircraft or engine. It is used to describe the specific propulsion system.
- It functions as a countable noun (e.g., , ).
Examples
- The regional airline operates a fleet of modern propjets.
- The propjet's efficiency makes it ideal for short-haul flights.
- Compared to a pure jet, a propjet is often quieter and more fuel-efficient at lower speeds.
Advanced Usage
- The term highlights the hybrid nature of the propulsion: the "prop" (propeller) is driven by a "jet" (turbojet core). This is its defining characteristic.
Variants and Related Words
- Turboprop (n): The more standard technical term for a propjet engine or aircraft.
- Propeller (n): The rotating blades driven by the engine to produce thrust.
- Turbojet (n): The type of gas turbine engine that forms the core of a propjet.
Synonyms
- Turboprop
Notes on Meaning
- The word specifically refers to the mechanical design where a jet turbine powers an external propeller. It does not refer to older piston-engine propeller aircraft.
Noun
- an airplane with an external propeller that is driven by a turbojet engine
