What part of the hot air balloon is referred to as the 'crown'?

The 'crown' of a hot air balloon specifically refers to the top section of the envelope, which is the fabric bag that holds the heated air. This area is crucial for the balloon's design and function, as it plays a significant role in maintaining the shape and integrity of the envelope. The crown helps to keep the heated air contained, allowing the balloon to rise when the air inside is warmed.

Understanding this term is essential for ballooning enthusiasts and professionals because it relates directly to the safe operation and aerodynamics of the balloon. Recognizing the crown’s importance can also help in maintenance and repairs, ensuring that the balloon stays in optimal flying condition.
