A320飞机复合材料尾翼活动面后缘设计改进的分析
Analysis of Improved Design for Composite Rudder and Elevator of A320

A320飞机尾翼的活动面（方向舵、升降舵）采用碳纤维复合材料蜂窝夹芯结构。阐述了A320飞机尾翼活动面在服役后的几次设计变更，针对几次改进设计构型通过FEM及CFD方法进行了数值模拟，研究了不同构型方案的特点，分析其改进的原因。
CFRP honeycomb sandwich structures are applied to the design of rudder and elevator of A320 aircraft. Several design evolutions of A320 empennage trailing edge in service were presented. Meanwhile,numerical simulations were carried out by means of FEM and CFD techniques. Main characteristics of different design configurations were studied and the reasons of these design evolutions were analyzed
