Meaning and Definition

An aerodynamic system used to assist in steering a ship, typically a freighter or tanker, which utilizes rotating cylinders (Flettner rotors) mounted vertically on deck to generate thrust via the Magnus effect.

A system of auxiliary ship propulsion and steering that replaces or supplements traditional rudders and sometimes even main engines. It is a specific application of the Magnus effect, where wind causes a spinning cylinder to create a perpendicular force, which can be harnessed for propulsion or to aid in precise maneuvering, especially at low speeds.

Common Mistakes When Using “flettner control”

  • Misspelling as 'Fletner' or 'Flettner Control' (capitalization varies; often capitalized as a proper noun).
  • Confusing it with the main propulsion system rather than an auxiliary control/assist system.
  • Using it as a verb (e.g., 'to Flettner control the ship' is non-standard).

FAQ

Frequently Asked Questions

It was invented by the German engineer Anton Flettner in the 1920s.

No, it is typically used on larger commercial vessels like freighters and tankers due to the scale required for effectiveness.

No, it is an auxiliary system that assists with propulsion and steering to improve efficiency, not a complete replacement for the main engine.

Because it harnesses wind power, reducing reliance on fossil fuels and lowering the ship's greenhouse gas emissions.
