Why does a blimp filled with helium float

Helium is very light. So balloons can float in air. A Helium filled baloon floats in air because Helium is lighter than air. Making it rise to the top of it. Because helium is lighter than air. Helium is lighter than air, hence balloons filled with helium will float upwards.

So balloons or air ships filled with helium will float. Because air is not as dense as helium filed gallons so they won't float. Hence balloons filled with helium will float up. A blimp gets lift from being filled with helium, which is lighter than air. A blimp floats on air because of this. They rely on the engines to move, but not to stay aloft. Because Helium makes the balloon float, if you use air then it will just fall to the ground.

However, the Hindenburg disaster ended the use of hydrogen in airships because hydrogen burns so easily. Helium, on the other hand, is not flammable.

While these lifting capacities might not seem like much, airships carry incredibly large volumes of gas -- up to hundreds of thousands of cubic feet thousands of cubic meters. With this much lifting power, airships can carry heavy loads easily. A blimp or airship controls its buoyancy in the air much like a submarine does in the water.

The ballonets act like ballast tanks holding "heavy" air. When the blimp takes off, the pilot vents air from the ballonets through the air valves.

The helium makes the blimp positively buoyant in the surrounding air, so the blimp rises. The pilot throttles the engine and adjusts the elevators to angle the blimp into the wind. The cone shape of the blimp also helps to generate lift. As the blimp rises, outside air pressure decreases and the helium in the envelope expands. The pilots then pump air into the ballonets to maintain pressure against the helium. Adding air makes the blimp heavier, so to maintain a steady cruising altitude, the pilots must balance the air-pressure with the helium-pressure to create neutral buoyancy.

To level the blimp in flight, the air pressures between the fore and aft ballonets are adjusted. Blimps can cruise at altitudes of anywhere from 1, to 7, ft to m. The engines provide forward and reverse thrust while the rudder is used to steer. To descend, the pilots fill the ballonets with air.

This increases the density of the blimp, making it negatively buoyant so that it descends. Again, the elevators are adjusted to control the angle of descent.
