传统的发动机转子爆破碰撞角度计算方法是AC20-128A中介绍的一种,实际应用中证明该方法无法真实反映在影响范围内的全部布置情况。本文主要对发动机转子爆破碎片的危害性以及其碰撞角度的计算方法进行了研究,介绍了一种利用CATIA运动模型计算碰撞角度的方法以及应用,可以用于飞机发动机转子爆破碎片对周围系统碰撞角度的计算。
The traditional calculation method of collision angle of engine rotor blasting is one introduced in AC20-128A, and the actual application proves that this method can not truly reflect the whole arrangement in the affected area. In this paper, the damage of the rotor rotor blasting debris and the calculation method of the collision angle are mainly studied. A method of calculating the collision angle by using the CATIA motion model and its application are introduced. The method can be applied to the collision of blasting fragments of an aircraft engine rotor to the surrounding system Calculation.
