The Boomerang Vent & Ballast Calculator is a critical tool for operators of the 4th Generation Boomerang Balloon Flight System. Using launch site, target altitude, and flight system parameters, the calculator displays:
- The initial helium fill volume and corresponding weigh-off weight to achieve a desired ascent rate, typically about 5 m/s.
- The estimated total vent time at altitude necessary for the Boomerang Balloon Flight System to achieve neutral buoyancy.
- The new ascent rate and settling altitude after a ballast drop of specific duration, either during the ascent or after reaching float.
