铺层参考方向选取对大展弦比机翼静气弹特性影响

以大展弦比机翼为研究对象,利用流固耦合方法对复合材料机翼铺层参考方向进行了数值模拟研究,分析了铺层参考方向轴偏角的改变对大展弦比机翼静气动弹性的影响．研究表明：铺层参考方向轴偏角的改变会对机翼气动弹性产生显著的影响．机翼的总体变形与扭转变形随着参考方向轴偏角的改变呈现周期分布;沿着机翼各个方向的挠度也会因为参考方向轴偏角的改变而产生不同的响应．

Effect of Layup Reference Direction Selection on the Aerostatic and Elastic Characteristics of High-Aspect-Ratio Wing

The layup reference direction of a composite wing with high-aspect-ratio was numerically investigated using the fluid-structure coupling simulation. The effects of the change of the deflection angle of the reference direction on the static aeroelasticity of the composite wing were analyzed. The results show that the change of the deflection angle of the lamination reference direction has a significant effect on the aeroelasticity of the wing. The overall deformation and torsional deformation of the wing show periodic distribution with the change of the deflection angle of the reference direction. The deflection along different directions of the wing will also exhibit different responses due to changes in the deflection angle of the reference direction.
