How massive ships change direction without reversing their engines
In short: Most people assume ships must move backward to go forward, but modern engineering allows for much more fluid control. This video explains the mechanics of controllable pitch propellers and the systems that keep them running smoothly.
The video explores the Controllable Pitch Propeller (CPP), a system where the angle of the propeller blades can be adjusted while the ship is in motion. This allows for precise thrust control and maneuverability without needing to change the rotation of the engine.
Key components highlighted include the oil distribution box, which powers the blade adjustments, and stern tube seals, which are critical for protecting the ship's interior from water while allowing the propeller shaft to rotate.
