PARTS OF A HOT AIR BALLOON
PARTS OF A HOT AIR BALLOON
Envelope: lightweight nylon material that contains the hot air needed for lift. Panels and Gores make up the envelope
Skirt: gathers the envelope together with a strong hoop shape that rests just above the burners.
Burners: heats the air that will rise inside the envelope
Parachute Valve: opens (when cord is pulled) to release hot air from the envelope. This controls the amount of lift and is used to land the balloon.
Wicker Basket: holds the load (people)
Propane Tanks: Fuel for the burners
Hot air balloons use the principle of “hot air rises” (air buoyancy) to fly.
Since hot air is lighter than cool air, it is less dense. A hot air balloon rises because it is filled with hot air, weighing less than the cooler dense air that surrounds it.
For more information, check out the "Properties of Air" section in the Air & Aerodynamics area!
A hot-air balloon has three essential parts:
The burner, which heats the air
The basket, which carries the passengers
The balloon envelope, which holds the air
