High-altitude stable and safe landing equipment is characterized in that a large opening is formed in the top of a parachute, a hydraulic buffer protection device is sleeved with the large opening, the protection device is composed of a hydraulic press, a pressure injection pipe, a folding support, a telescopic foot stool and a foot stool upper belt, and a propeller is installed on a pressure pull rod of the hydraulic press. When the equipment is used for airborne landing, the propeller is firstly opened, the propeller rotates at a high speed under the effect of high-speed airflow, the stabilizing and preliminary speed reducing effects are achieved, and the rotating propeller can further enable the hydraulic buffering protection devices to be automatically opened and the telescopic foot stools to stretch out to protect loaded people or objects; and when the parachute descends to a proper height, the parachute is opened, and the speed is further reduced. When the parachute falls on the ground, the front end of the telescopic foot stool firstly touches the ground, and then the loaded person or object slowly touches the ground. Therefore, stable and safe airborne landing is realized.
一种高空平稳安全降落设备,它把降落伞的顶部开一个大口,大口内套装一个液压缓冲保护装置,保护装置由液压器、注压管、收合支架、伸缩脚架和脚架帮带组成,在液压器的压力拉杆上安装一个螺旋桨。使用本设备空降时,先打开螺旋桨,在高速气流的作用下,螺旋桨高速旋转起来,起到稳定和初步降速作用,旋转的螺旋桨还能使液压缓冲保护装置自动打开,伸缩脚架伸展开来,护住负载的人或物;下降到合适高度的时候,再打开降落伞,进行进一步降速。落到地面时,伸缩脚架的前端先触地,负载的人或物再慢慢着地。从而实现平稳安全空降。
