A hot air sky balloon, commonly known as a hot air balloon, is a large, balloon-like aircraft that uses heated air to lift off the ground. They are often used for recreational flying, advertising, and special events. Here’s a detailed overview:
Key Features of Hot Air Sky Balloons
Structure:
Envelope: The large, fabric balloon that holds the hot air. It is usually made of nylon or polyester.
Basket: The compartment that carries passengers and the pilot. It’s typically made of wicker or a metal frame.
Burner: The device that heats the air inside the envelope. It runs on propane and is mounted above the basket.
Inflation:
Pre-Inflation: The envelope is first partially inflated with cold air using a fan.
Hot Air Inflation: The burner is then used to heat the air inside the envelope to create lift.
Size:
Hot air balloons come in various sizes, from small ones for a few passengers to large ones that can carry several people.
Operation:
Control: The pilot controls the balloon by adjusting the burner to heat the air or by venting hot air to descend.
Navigation: Hot air balloons rely on wind currents for movement, so the pilot has limited control over direction and must plan the flight accordingly.

Branding: Balloons can be customized with logos and messages for promotional purposes.
