How do submarines prevent themselves from rolling over?
Submarines are designed to be stable in water and prevent rolling over due to several factors:
- Ballast Tanks: Submarines have ballast tanks that can be filled or emptied with water, which shifts the center of gravity and keeps the submarine upright.
- Hydroplanes: Submarines have movable control surfaces called hydroplanes, located at the front and rear of the hull. By adjusting the angle of the hydroplanes, the submarine can steer and maintain its desired depth.
- Shape: The streamlined shape of submarines reduces drag and minimizes the risk of rolling over.
- Buoyancy: Submarines maintain a certain level of buoyancy to keep them afloat. If they lose buoyancy, they can use emergency ballast tanks to restore stability.
- Keel: The keel, which is a heavy weight along the bottom of the submarine, helps to keep it stable.
