This is a US Navy free balloon as used for initial lighter-than-air training during the 1920s to 1940s. It is fairly representative for a type of aircraft that first flew in 1783 and soon afterwards found a shape and construction that it retained (almost) to this day.
Handling instructions
Important controls / keys
Flight controls
- Gas valve
- Ballast
Ballast
- W - Weigh-off to 10% of current weight by dropping ballast. Takes about 10 seconds and only works when on the ground.
- w - Show current on-ground weight. Only works when on the ground.
- D/d - Drop ballast in 1%/0.1% decrements.
Gas
- F/f - Open/close the gas valve.
- R - Rip the envelope. Use only close to the ground and when you really really want to stay there.
External links
- A very good resource for information about and instructions for gas ballooning. Has links to couple of (old but good) books available in PDF format.
- Theory of Ballooning, War Department, 25 Apr, 1940. The basics in 13 pages.
