Continuous throwing ballast-based stratosphere air boat raising method

The invention discloses a continuous throwing ballast-based stratosphere air boat raising method and relates to an air boat. In a raising process, raising is realized by depending on static buoyancy through ballast throwing and exhaustion, and at any time in the whole raising process, the static buoyancy is kept to be equal to the gravity of the air boat approximately all the time; the raising speed V is controlled to be greater than 0 and smaller than or equal to 10m/s, the raising process includes an acceleration phase, a uniform velocity phase and a decelerating phase, and the uniform velocity phase is the main phase; the internal and external pressure difference of the air boat is kept to be 200 to 1,000Pa all the time; the executing way of the raising process includes two phases, i.e. (1) an exhaustion and blast throwing raising phase, and (2) a complete exhaustion raising phase. According to the continuous throwing ballast-based stratosphere air boat raising method, the air boat can be stably raised to the lower part of a stratosphere by only depending on the static buoyancy without the need of raising force in the vertical direction provided by a propelling system, and in the raising process, the internal and external pressure difference of an air bag is kept to be within a preset range.
