Gas-Bag Arrangements TRIZ Cases
- Rotatable Balloon Envelope for Solar Buoyancy Control
By rotating envelope sections with different solar absorption, the balloon adjusts gas heating for altitude control and stratospheric station-keeping.
- Ballonet Optical Volume Measurement for Airship Balance Control
Laser sensing improves ballonet volume accuracy for airship balance control.
- Passive Valve Balloon Altitude Control
Impeller pressure opens a passive valve to fill a bladder, enabling altitude control without electrical actuators.
- Internal Ballast Compartments for High-Altitude Lighter-Than-Air Vehicles
A lighter-than-air vehicle integrates internal ballast compartments separated by a flexible barrier to manage buoyancy and release gas through a valve.
