ballonet
Airship pressure compartment
A ballonet is a small air compartment inside an airship or balloon.
As the main gas bag expands or contracts with altitude and temperature changes, air is pumped into or released from the ballonet to maintain the craft's shape and pressure.
Most dirigibles have multiple ballonets for trim control.
