Definition

1. 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

1. an airplane with an external propeller that is driven by a turbojet engine
