🚢 How do submarines work?

Submarines are like big underwater boats! � They can go up and down in the water like a fish. 🐟

They have special tanks called ballast tanks. When they fill with water, the submarine goes down. When they push the water out, the submarine goes up! 🌊

They also have propellers to move forward, just like a fan pushes air. 💨

Submarines are amazing machines that can travel underwater for long distances! 🌊🚢

They use ballast tanks to control their depth. When water fills these tanks, the submarine becomes heavier and sinks. When compressed air pushes the water out, it becomes lighter and rises. ⚖️

Submarines also have propellers powered by engines or nuclear reactors to move forward. They use rudders and diving planes to steer, just like an airplane’s wings! ✈️

Inside, they carry oxygen generators and filters to keep the air clean for the crew. 👨‍✈️

Submarines are highly advanced vessels designed for underwater exploration, military missions, and scientific research. 🌊🔬

They operate using the principles of buoyancy and hydrodynamics. Ballast tanks adjust weight by taking in or expelling water, while diving planes and rudders control direction. Nuclear-powered submarines use reactors to generate electricity, allowing them to stay submerged for months! ⚡

Key systems include:

• Sonar (sound navigation and ranging) to detect objects underwater.
• Periscopes for viewing the surface while submerged.
• Oxygen generators and CO₂ scrubbers to maintain air quality.

Modern submarines can dive deeper than 500 meters and travel at speeds over 40 knots (74 km/h)! 🚀
