[Problem] To obtain a parachute that can be quickly deployed compared to the prior art, a safety device provided with the parachute, and an aircraft provided with the safety device. [Solution] A parachute body (40) of a parachute has a substantially hemispherical shape provided with a first shock-absorbing part (40A), a second shock-absorbing part (40B), and a shape-retaining part (40C), and has an air vent (40a) formed at the top of the top of the parachute, and a parachute edge part (40b) constituting an opening part. The first and second shock-absorbing sections (40A, 40B) are formed in a state in which a plurality of base cloths are disposed such that a center line (L) connecting the apex (P) and the geometric center position of each base cloth intersects the direction in which the warp and weft of the base cloths extend. The second shock-absorbing section (40B) is more difficult to expand and contract than the first shock-absorbing section (40A), but is easier to expand and contract in the direction along the center line (L) than the shape-retaining section (40C) that is relatively difficult to expand and contract.
[课题]得到一种与以往相比能够迅速展开的降落伞、具备该降落伞的安全装置、以及具备该安全装置的飞行器。[解决方法]降落伞的伞体40为具备第1冲击缓冲部40A、第2冲击缓冲部40B和形状保持部40C的大致半球状,具有形成在头顶部的通气口40a和构成开口部的伞缘部40b。第1冲击缓冲部40A和第2冲击缓冲部40B以连接顶点P和各基布的几何中心位置的中心线L与基布的经纱和纬纱的延伸设置方向交叉的方式分别配设多个基布的状态而形成。第2冲击缓冲部40B与第1冲击缓冲部40A相比难以伸缩,但与相对难以伸缩的形状保持部40C相比,在沿着中心线L的方向上容易伸缩。
