Title:
AEROSTAT WITH PHASE CHANGE ADJUSTMENT AIRBAG
Document Type and Number:
WIPO Patent Application WO/2022/141777
Kind Code:
A1
Abstract:
An aerostat with a phase change adjustment airbag, the aerostat comprising a main airbag (302); a load nacelle (308), which is used for containing a mission apparatus and a mission load; a phase change adjustment airbag (330), which is used for directly or indirectly adjusting the pressure difference of an aerostat, so that the pressure difference is kept within a safe range when the height of the aerostat changes; a phase change working medium gas (332), which is used for filling the phase change adjustment airbag (330); a phase change apparatus, which is used for regulating and controlling the volume of the phase change working medium gas (332) in the phase change adjustment airbag (330), and comprises a liquefying/desublimation device (336), a gasifying/sublimation device (338), a storage tank (334) for storing a liquid-phase/solid-phase working medium, and phase change electronics and an accessory (340); and a control system. According to the solution, a redundancy mode of directly adjusting a height by means of a phase change is provided, and a favorable pressure difference condition can also be created for the working of a complex air pump; in addition, during a height change control process, it is always ensured that the pressure difference of a balloon body is within a safe range, thereby realizing optimized coordination between the height control and pressure difference control.
