The invention discloses a large-scale rigid-flexible combined structure stratospheric airship, and relates to the technical field of aerostats. The airship comprises an outer bag body, an inner bag body, sunflower-shaped suspension partitions, a bottom web keel, a nose cone, an empennage, a propeller, a solar cell and an undercarriage. The outer bag body is an airtight bag body structure, air is filled in the outer bag body, and a form and rigidity of the bag body are kept through an internal and external air pressure difference. The plurality of sunflower-shaped suspension partitions are arranged in the outer bag body in a longitudinal direction, the interior of the outer bag body is divided into a plurality of air cabins, inner bag bodies are arranged in the air cabins, and buoyancy working medium helium is arranged in the inner bag bodies; and the bottom web keel is located on a bottom web portion of the outer bag body and arranged on an airship body section in the longitudinal direction. An overall structural mechanical property of the stratospheric airship can be improved, system design, manufacturing and integration technical difficulty and the overall cost are reduced, and an industrial application level of the stratospheric airship is improved.
本发明公开了一种大尺度刚柔性组合结构平流层飞艇,涉及浮空飞行器技术领域,包括外囊体、内囊体、葵花形悬挂分隔、底腹龙骨、头锥、尾翼、推进器、太阳能电池、起落架;外囊体为气密性囊体结构,外囊体内为空气,由内外气压差保持囊体形态和刚度;外囊体内部沿纵向设置多个葵花形悬挂分隔,将外囊体内部分隔为多个气舱,气舱内设置内囊体,内囊体内是浮力工质氦气;底腹龙骨位于外囊体底腹部,沿纵向设于飞艇主体区段。本发明可提高平流层飞艇的整体结构力学性能,降低系统设计、制作、集成技术难度和总体成本,提高平流层飞艇的工业化应用水平。
