摘　　要：文章对国外相关实验及计算工作进行了综合分析 ,指出高空侧向风容易引起开伞过程的“绳帆”现象 ,从而导致严重的后果 ,总结了消除此现象的若干种对策。并介绍了国外通过计算机模拟“绳帆”问题在实际飞行中得到的成功应用 ,建议中国也开展相应的理论分析和软件研制工作。After detail description of foreign research in experiments and numerical computations, this paper points out that the line sail phenomena caused by the cross wind during parachute deployment will lead to severe aftereffects, and then concludes some feasible ways to eliminate this phenomena. Finally, concerned that computer_aided 'line sail' simulation successfully applied in parachute industry, practicable solutions of theoretical analysis and softw are development are presented to our research work.
