摘要

摘要降落伞系统在航空中广泛使用。到目前为止，降落伞是最不确定的飞行器，因为它们具有复杂和不稳定的开口特性，几何形状变化高达30%，并且容易受到不稳定大气湍流的影响。疲劳是长寿降落伞系统设计者需要解决的一个问题。作者展示了降落伞开发的复杂性，以及在不影响安全的情况下降低打开力和延长使用寿命的方法。

Fatigue Degradation of the Structure of Parachute Systems

Abstract Parachute systems are in widespread use in aviation. Up to now, parachutes are the most uncertain air vehicles because of their complex and unsteady opening characteristics, changes in geometry up to 30% and vulnerability from unsteady atmospheric turbulence. Fatigue is a problem that the designers of long living parachute systems need to cope with. Authors demonstrate complexity of parachute exploitation and means to lower opening forces and extend service life without influencing safety.
