Equations Derived for Computer Programming of Helium Inflations for Large Plastic Balloons.
Abstract
Helium inflation computations for large plastic research balloons are normally accomplished by a tedious mathematical procedure involving the use of tables which indicate available lift per tube at specified gas trailer pressures and temperatures. The tables evolved from MIT empirical data, and now have been approximated to within 0.1 lb of lift by a set of equations specifically developed for use in computer programs. The history of the tables, the advantages of converting from manual to computer processing of inflation computations, and resultant accuracies are covered in the report. (Author)
