针对某型导弹出现的翼面细微裂纹故障,分析了裂纹的形成机理,计算了翼面裂纹扩展速度和可使用循环次数,认为裂纹在导弹挂飞时不会进一步扩展,在机动飞行时仍可承受较多的脉动循环周次。
Aiming at the crack of a small airfoil on a certain type of missile, the formation mechanism of crack is analyzed. The crack propagation speed and the number of cycles available are calculated. It is believed that the crack will not expand further when the missile is flying, Bear more pulsations cycle week.
