Navy Tests New Propellor Technology

The video discusses the revolutionary cycloidal propeller, invented by Frederick Kirsten, which allows ships to make complete turns and move sideways without traditional rudders. The propeller's design, likened to an egg beater, features blades that rotate on their own axes with controllable pitch. Installed on a landing ship, the propeller provides exceptional maneuverability without sacrificing speed. The video highlights the potential for widespread use of this technology in various types of ships, emphasizing its advantages in tight spots and slow movements.
