SB-279-250 member of the Silver Blimp Line of airship envelopes.
This is a big balloon with a larger diameter intended for airships that still fit inside a car, but can already carry a reasonable payload.
Two gore envelope produced from robust Aluminum/Nylon/Polyethylen multilayer material by heat welding. Filling tube in tail section, with closing clip included.
These envelope types are used in model airships like the silent_runner
Created with the Gertler Shape Generator after J. Eissing.
When using the envelope be aware of:
- Sharp things
- Hot things
- Large temperature differences
But yes, it´s so strong you can sit on it. If carefully deflated and folded after usage, these envelopes can last for many years.
