What does the term 'gore' refer to in the context of hot air balloons?

In the context of hot air balloons, the term 'gore' refers specifically to a vertical section of the balloon's envelope. The envelope is the large fabric structure that holds the hot air, allowing the balloon to rise and float.

Each 'gore' is typically a panel sewn into the envelope, allowing for a more aerodynamic shape and ensuring that the balloon can regulate the flow of warm air effectively. This construction provides structural integrity and a smooth surface to optimize lift and control. Each gore contributes to the overall performance and balance of the hot air balloon by distributing the stress of the hot air evenly across the envelope.

Understanding the design and function of gores is essential for comprehending how hot air balloons operate and why their construction is important in maintaining stability and safety during flight.
