What Are Flettner Rotors
II
Flettner Rotors are smooth cylindrical rotors that which is spun along the long axis which has the smallest moment of inertia.
How does it work
- Fundamental of Magnus effect.
- The vertical pillars spin, rotate - introduced to an air current, they develop lift.
- Manually driven to control propulsion power and generate lift.
- Manoeuvrability is limited by the wind speed and direction of current.

Applications
IV
Ships
1
The Flettner system serves 2 main purposes on board a ship:
1. For propulsion
2. For stabilization
Planes
2
The rotor comprises a spinning cylinder with circular end plates and, in an aircraft, spins about a horizontal axis. When the aircraft moves forward, the Magnus effect creates lift.
Advantages
Flettner Sail
V
1) Ships fitted with Flettner rotors can sail even when the wind is not in the direction of sailing.
2) The rotor sail is said to be 10 times more efficient than a conventional sail, creating more lift with a smaller surface area.
