Definition

1. Noun:
   • A propeller plane with an engine that drives two propellers in opposite directions (for stability): A type of aircraft powered by a single engine that turns two propellers; the propellers rotate in opposite directions to counteract each other's torque, providing greater stability.

Usage Examples

• Noun:
  • The vintage double-prop was a common sight at the small airfield.
  • For training purposes, the school used a reliable double-prop.

Advanced Usage

• Technical Context: In aviation history and engineering, "double-prop" specifically refers to the propulsion system design, not merely any twin-engine aircraft. The key feature is the single engine driving two counter-rotating propellers.
  • The aircraft's unique handling characteristics were due to its double-prop configuration.

Variants and Related Words

• Double-propeller plane: A fuller, more descriptive term with the same meaning.
• Counter-rotating propellers: The technical term for the key mechanism of a double-prop.
• Single-engine twin-prop: A phrase sometimes used to describe this setup, emphasizing the single power source.

Synonyms

• Twin-prop (with context): While "twin-prop" can often refer to a plane with two separate engines, it may be used informally for a double-prop when the counter-rotating feature is understood from context.
• Counter-rotating propeller aircraft: A precise technical synonym.

Related Phrases

• Drives two propellers: The core action describing the function of the engine in a double-prop.
  • The engine drives two propellers on a single shaft.
