The invention relates to the technical field of reentry capsules, in particular to a flexible reentry capsule capable of avoiding overturning. The flexible reentry capsule capable of being prevented from being overturned comprises the flexible reentry capsule capable of being prevented from being overturned and a capsule body. The air bag comprises a bottom and a side part, the bottom is suitable for making contact with the ground during landing, the side part is suitable for surrounding the periphery of the capsule body after expansion, a plurality of folding parts are arranged at the joint of the bottom and the side part in the circumferential direction of the capsule body and folded towards the interior of the air bag, and the top of each folding part is connected to the inner wall of the air bag through a first line and a second line; the first line and the second line both surround the airbag by one circle, the tensile strength of the second line is greater than that of the first line to avoid breakage of the first line when the airbag expands, and the first line is suitable for breakage during landing; and the fusing structure is suitable for fusing the second wire after the air bag completes expansion. According to the flexible reentry capsule, the folding parts on the flexible reentry capsule expand outwards to increase the landing area of the air bag, so that the landing stability is improved, and overturning is avoided to a certain extent.
本发明涉及返回舱技术领域,具体涉及一种可避免翻倒的柔性返回舱。可避免翻倒的柔性返回舱包括:本发明提供的可避免翻倒的柔性返回舱,舱体;气囊,其包括底部和侧部,底部适于着陆时接触地面,侧部适于膨胀后包围于舱体外围,底部和侧部交接处沿舱体的周向设有多个折叠部,折叠部向气囊内部折叠,折叠部的顶部通过第一线和第二线连接在气囊的内壁上,第一线和第二线皆绕气囊一周,且第二线的拉伸强度大于第一线以在气囊膨胀时避免第一线断裂,第一线适于在着陆时断裂;熔断结构,适于在气囊完成膨胀后熔断第二线。本发明的柔性返回舱,其上的折叠部外胀会增加气囊的着陆面积,从而提高了着陆稳定性,在一定程度上避免翻倒。
