The invention discloses a variable resistance area type parachute structure and a parachute opening method. The variable resistance area type parachute structure comprises a large parachute component, a small parachute component and a disengaging mechanism. The large parachute component comprises a large parachute canopy and a large parachute connecting rope, the small parachute component comprises a small parachute canopy and a small parachute connecting rope, the small parachute canopy is arranged in the center of the top in the large parachute canopy, and the large parachute canopy is connected with the first disengaging mechanism through the large parachute connecting rope; the small parachute canopy is connected with the separation mechanism connecting piece II through a small parachute connecting rope; the first disengaging mechanism connecting piece and the second disengaging mechanism connecting piece are connected with a disengaging mechanism used for changing the working state of the parachute, and the total length of the small parachute component is not equal to the total length of the large parachute component. Two parachutes with different areas needed in the air-drop process are combined into a whole, the weight and size of the parachute are reduced, the structure is simple, the working procedure is simplified, and economical efficiency is high.

    本发明公开了一种可变阻力面积式降落伞结构及开伞方法,包括大伞部件、小伞部件和脱离机构;所述大伞部件包括大伞伞衣和大伞连接绳,所述小伞部件包括小伞伞衣和小伞连接绳,所述小伞伞衣设置于大伞伞衣内顶部中心部分,所述大伞伞衣通过大伞连接绳与脱离机构连接一连接;小伞伞衣通过小伞连接绳与脱离机构连接件二连接;所述脱离机构连接件一和脱离机构连接件二分别与用于改变降落伞工作状态的脱离机构连接,小伞部件的总长度与大伞部件的总长度不相等。本发明将空投过程中需要的两种不同面积的降落伞合二为一,减小降落伞的重量体积,且结构较为简单,简化了工作程序,经济性较高。
