Parachute is a kind of aerodynamics decelerator with rarious application.The experiment costs a great deal of money during the development of parachute.

The drogue chute is a small parachute that is used by skydivers to open the main parachute.

阻力伞是一个小降落伞的跳伞是用来打开主降落伞。

Based on the finite element method, the multi-mass dynamic model of a recovery parachute system is developed to study the main parachute performance using an attached apex drogue during the deployment.

采用有限元方法，建立降落伞回收系统的多质点动力学模型，研究了牵顶伞在拉直过程中对主伞性能的影响。

These factors and others which influence parachute drag is covered indetail in a book such as Parachute Recovery Systems Design Manual.

不过，我将讨论一下这些因素在这里，因为他们感兴趣的任何希望利用降落伞作为一个复苏的装置。

It often happens that the parachute is too difficult, or even impossible, to extract from it's container (especially for less aggressive persons) because of too much Velcro, or deployment pins which are too long. In certain cases, if the pilot's in a spin, it's not even realistic to grab the handle of many parachute systems. After having mounted a parachute on a harness, it's vital to do a hang check to verify that the deployment handle is truly easy to grab and that the parachute can be pulled from the container with minimal effort and in any variety of pilots position and circumstances. Seems obvious, but almost no one actually does it!

而时常发生的情况是由于过多的尼龙搭扣，或者保险销过长导致备份伞很难，甚至是根本不可能从吊带里面抽出来（尤其是对于那些体力较差的飞行员）；在某些状况下，比如在螺旋当中，很多备份伞系统的备份伞手柄根本就不可能抓到；因此在安装好备份伞之后务必要做悬挂检查：将吊带吊起来，自己坐在上面模拟在各种飞行状态下是否能够轻易而迅速的抓住手柄将之抛出来；显然，没有多少人做过这个模拟。

It is similar to parachute jumping without a parachute.

这是类似的跳伞，没有一个降落伞。
