The technical problem of the balloon air-staying platform loaded in the shell is studied
and the corresponding method and equipments are proposed.Gas storage in the limited shell is realized by optimizing the design of pressure vessel.Fast gas-charging problem is resolved by adopting the high pressure gas charging technique.Stable-suspension of mission equipment is settled by using captive rope control.The theory calculation shows that the designed equipment can realize the balloon stale suspension under the projectile condition
and the method can be referenced to study and practical application.
