The invention provides a retractable airship air cushion landing device which comprises an inflatable cushion used for being installed at the bottom of an airship and an air conveying mechanism used for executing air exhaust or air inflation work, the inflatable cushion is of an annular structure, and a flexible apron board arranged in the circumferential direction is arranged at the bottom of the inflatable cushion; the flexible apron board is provided with a plurality of air bags which are evenly distributed in the circumferential direction of the inflatable cushion and are independent of one another, all the air bags are communicated with the inflatable cushion, and air holes are formed in the bottom and the inner side wall of each air bag. The air conveying mechanism is connected with the inflatable cushion so as to inflate or deflate the interior of the inflatable cushion. The airship landing gear device can replace a traditional landing gear device to be applied to application scenes such as airship landing buffering, ground hovering and traction, the take-off and landing capacity of an airship under complex ground conditions such as sand, snowfield, ice surface and water surface is improved, and a mooring tower or an anchoring vehicle does not need to be arranged. And the flexible apron board can protect the inflatable cushion from being rubbed with the ground, the damage of the single independent air bag does not influence the overall performance of the system, and the reliability of the system is improved.
本发明提出了一种可收缩式飞艇气垫着陆装置,包括:用于安装在飞艇底部的充气垫、以及用于执行抽气或充气工作的运气机构,其中:充气垫为环形结构,充气垫的底部设有周向设置的柔性裙板,柔性裙板具有若干个沿充气垫的周向均布并相互独立的气囊,各气囊均与充气垫连通,且每个气囊的底部及内侧侧壁均设有气孔;运气机构与充气垫连接以用于向其内部充气或抽气。本发明能够替代传统起落架装置应用在飞艇着陆缓冲、地面悬停及牵引等应用场景,提升飞艇在沙地、雪地、冰面、水面等复杂地面条件起降能力,不需要配备系留塔或锚泊车。且柔性裙板能够保护充气垫不与地面发生摩擦,独立的气囊单个损坏不会影响系统的整体性能,提高了系统的可靠性。
