飞机轮胎所造成的砂石飞溅数目的计算方法

 飞机在起飞和降落时,由于轮胎的影响所造成的跑道上外来物(FOD)飞溅是个复杂的过程。以砂石为例,介绍了几种典型的砂石飞溅的类型,提供了飞机所能遭遇到的砂石数目和造成飞机结构损伤的概率计算公式。以某型客机为例,根据民用机场的FOD调研报告和国内民用机场跑道的类型,分析了在临界能量下飞机所能遭遇到并能对飞机造成冲击破坏的可能性,为飞机结构抗冲击设计提供一定的依据。

Calculational Method of Sandstones Rolled up by Airplane Tyres

When an airplane takes off and lands, the foreign objectd damage (FOD) splash made by its tyres on the airport runway is a very complex process. Taking sandstone as an example, a number of classical types of sandstone splash are introduced, and a few formulas are given which calculate the number of the sandstones that the airplane meet and the probability of the airplane structure damage. Then a passenger plane made in China is taken for example. The paper analyzes the damage probability of the airplane structure impacted by sandstones with critical energy according to the FOD report of the civil airport and the type of the airport runway. This study can provide useful reference for airplane structure anti-impact design.
