| 目的 解决某型机跳伞过程中开伞拉绳缠挂跳伞员肢体的问题。方法 通过对空降兵主战伞型稳定伞包装方式的改革设计，在不破坏主伞主体包装方式的基础上，对降落伞二级开伞的稳定伞进行结构微改设计，实现稳定伞外置包装，使稳定伞系统变为打开主伞伞包的一部分，从而间接缩短预留在飞机跳伞钢索上拉绳的长度。结果 改变二级跳伞稳定伞的包装方式后，跳伞员跳伞过程中，预留在飞机跳伞钢索上的开伞拉绳长度缩短为600 mm，与原来相比缩减1500 mm，增大了跳伞拉绳受飞机尾流作用内甩与跳伞员离机瞬间的距离，做到了两者不再相互缠挂。经过地面模拟和空中试验，跳伞员在进行某型机跳伞时，没有再发生跳伞拉绳缠挂跳伞员肢体的特殊情况，确保了跳伞安全。结论 该改装设计方案可行。 |
| 英文摘要: |
| This paper aims to solve the problems that the parachute cord entangles the parachutists’ limbs in the parachute process of a certain type of airplane. By reforming the design of the pack methods of the main battle drogue parachute for our airborne troops, the structure micro modifications on the second level opening drogue parachute were done based on not doing harm to the main pack methods of the main parachute to achieve drogue parachute external package, and to make the drogue parachute system a part of the opening main parachute pack to indirectly shorten the cord length reserved on the parachute cable in the airplane. After changing the pack methods of the second level drogue parachute, the parachute-opening cord length reserved on the parachute cable was shortened to 600 mm (reduced by 1500 mm), which enlarged the distances between the cord affected by the airplane wake to throw inward and the parachutist deplaning in the instant, and ensured both of them were no longer bound to each other. The parachutists had no more the cord entangling the limbs accidents in a certain parachute by ground simulation and air experiment, which guaranteed the parachute safety. In conclusion, the modification design scheme is feasible. |
