STRATOSPHERIC AIRSHIP OF LARGE-SCALE RIGID AND FLEXIBLE INTEGRATED STRUCTURE

WIPO Patent Application WO/2021/068457

A1

Disclosed is a stratospheric airship of a large-scale rigid and flexible integrated structure, the stratospheric airship comprising an outer capsule body (103) and a keel (101), wherein the outer capsule body covers the keel. The keel comprises a core shaft truss (10102), stiffening rings (10101) and a string secondary keel (102), wherein the core shaft truss extends in the length direction of the stratospheric airship; the plurality of stiffening rings are coaxially arranged in parallel in the length direction, and the centers of the stiffening rings are connected to the core shaft truss; and the string secondary keel is connected to outer rings of adjacent stiffening rings in the head region of the stratospheric airship. The appearance of the outer capsule body of the stratospheric airship is substantially not affected by environmental changes, pressure and buoyancy can be subjected to decoupling control, and the center of mass is stable. In addition, an environment control system, a propelling system, an energy system, and a return flight buffering system are optimized. The stratospheric airship has a stable posture, low energy consumption, flexible and controllable lift-off and return flight, a strong long-term airborne capacity and a wide industrial application prospect.
