摘要： 为了提高航空发动机非包容性失效条件下飞机蒙皮的抗击穿能力,需要根据非包容性碎片特性和蒙皮破坏的特点,合理评估蒙皮破坏时的能量损耗.为此,借鉴平头圆柱体冲塞破坏能量模型,在考虑整体弯曲变形和局部剪切变形的基础上,采用长方体叶片碎片当量化的方法,提出了适用于长方体碎片的冲塞破坏能量模型.在此冲塞破坏能量模型的基础上,结合航空发动机典型的非包容性碎片特性,给出非包容性失效条件下的飞机蒙皮最小厚度算法.最后通过算例校验了算法的有效性.

Abstract:  In order to improve the impact resistance capability of the aircraft skin under the event of uncontained gas turbine engine, it is required to estimate the energy which is needed to destroy the skin according to the characteristic of the uncontained debris and the failure model of the skin. Therefore, based on the shear plugging energy model of the rigid flat-ended cylinder projectiles, and considering the global deformation and local shear deformation, the plugging energy model of the cuboid debris was raised with the means of normalization. And with the raised energy model and the data of the typical uncontained engine debris, the algorithm of aircraft skin thickness was proposed for the aircraft design. Finally, an example of the algorithm was given which showed the algorithm was available．
