1. A hull parameter setting method of setting parameters of a hull of an airship provided with a Helium room and an air room separate from said Helium room, comprising:

  • launching observation means configured to observe upper ambient air environment immediately before launching said airship in order to acquire ambient air data on actual conditions of upper ambient air including altitude, pressure, wind direction, wind speed and temperature;

    determining an ascension profile for said airship by a simulation using said ambient air data on said actual conditions of said ambient air;

    determining an initial quantity of a Helium gas in said Helium room of said airship conforming to said actual conditions of said ambient air; and

    adjusting a quantity of said Helium gas contained in said Helium room to said initial quantity of said Helium gas to set an initial buoyancy.
