What is balloonet?

A balloonet is a small balloon located inside a larger balloon or airship envelope used to maintain pressure to prevent the envelope from collapsing. The balloonet is filled with air or gas and is connected to the gas or air collecting system. The function of the balloonet is critical for the stability and performance of the airship or balloon and for the safety of passengers and cargo. Balloonets are particularly important in airships because they allow for adjustments in buoyancy as the airship's gas expands or contracts due to changing atmospheric conditions. Overall, balloonets play a crucial role in ensuring the safety and success of balloon and airship flights.
