Definition

Noun: A propeller-driven aircraft powered by a single engine that rotates two propellers mounted on the same axis but spinning in opposite directions. This counter-rotation is designed to improve stability and efficiency by canceling out the torque effect produced by a single rotating propeller.

Usage

The term "twin-prop" specifically describes the propulsion system of the aircraft. It is a technical term used in aviation contexts. * The museum's collection includes a classic twin-prop from the 1950s. * For short regional routes, a twin-prop aircraft is often more economical than a jet.

Advanced Usage

• The term is often used attributively (like an adjective) to modify other nouns related to aviation.
  • The airline is updating its twin-prop fleet with newer models.
  • We experienced some turbulence on the twin-prop commuter flight.

Variants and Related Words

• Twin-propeller (adj): The full adjectival form.
  • a twin-propeller aircraft
• Counter-rotating propellers: The technical name for the propulsion system described by "twin-prop."
• Single-engine twin-prop: A more precise description to distinguish it from multi-engine aircraft.
• Propeller plane / Prop plane (n): The general category to which a twin-prop belongs.

Synonyms

• Propjet (Note: This can sometimes refer to a turboprop engine, which is a jet engine driving a propeller, and may not specify counter-rotation.)
• Counter-rotating propeller aircraft

Notes

• "Twin-prop" is a compound noun. It should not be confused with "twin-engine prop," which refers to an aircraft with two separate engines, each driving one propeller.
• The primary advantage highlighted by the term is the stability gained from the counter-rotating propellers, which eliminates the aircraft's tendency to yaw (turn to one side) due to engine torque.

Noun

1. a propeller plane with an engine that drives two propellers in opposite directions (for stability)
