The invention discloses a variable-resistance-surface parachute and a parachute opening method, and relates to the field of parachutes. The variable resistance surface parachute comprises a brake parachute, and further comprises at least two groups of parachute cords connected to the brake parachute, connecting belts in one-to-one correspondence with the parachute cords in each group and at least one delay separator, the parachute cords in each group are arranged at intervals in the circumferential direction of the brake parachute, the parachute cords in each group are arranged at intervals in the radial direction of the brake parachute, one end of each connecting belt is connected with each parachute cord in the corresponding group, and the other end of each connecting belt is connected with the corresponding delay separator. The other end is connected with the top of the parachute; the connecting belts corresponding to the parachute cords located on the inner side are connected with the top of the parachute through delay separators respectively, the lengths of the connecting belts corresponding to the parachute cords are sequentially increased from inside to outside, and the corresponding connecting belts are cut off after the delay separators corresponding to the parachute cords are sequentially spaced for preset time from inside to outside. According to the variable-resistance-surface parachute and the parachute opening method, the degree of full inflation of the parachute canopy is restrained by restraining the parachute ropes, and therefore the unfolding area of the brake parachute can be adjusted according to the parachute opening requirement.
一种变阻力面降落伞及开伞方法,涉及降落伞领域。变阻力面降落伞包括减速伞,还包括至少两组连接于减速伞的伞绳、与每组伞绳一一对应的连接带及至少一个延时分离器,每组伞绳均沿减速伞的周向间隔布置,各组伞绳沿减速伞的径向间隔布置,连接带的一端连接对应组各根伞绳,另一端用于连接降落伞顶部;位于内侧的各组伞绳对应的连接带分别通过一延时分离器连接降落伞顶部,各组伞绳对应的各个连接带的长度从内至外依次增大,各组伞绳对应的各个延时分离器从内至外依次间隔预设时间后切断对应连接带。本申请提供的变阻力面降落伞及开伞方法通过约束伞绳来约束伞衣张满充气的程度,从而可根据开伞需要对减速伞的展开面积进行调节。
