摘要
介绍了两种锥形降落伞的设计。一种伞型使用了零透气量纺织材料，另一种伞型使用了微透气量纺织材料。两种伞型均使阻力系数值达到１．２，从而显著减少了伞衣面积，降低了伞衣重量。
Presents two types of the conical parachute design. One type uses the cloth withlow air permeability for the canopy. The another uses the cloth with zero air permeability.Thecanopy drag coefficient of the two parachutes is increased to 1. 2 and, therefore,the area andthe weight of the parachute canopy are remarkably decreased.
