Research on the Effect of Layering on the Failure of Helicopter Fairing
The fairing of helicopter has the functions of dimensional rectification,wrapping antenna,etc,in the structural design,it is necessary to predict the failure mode of the structure to guide the structural design and improve product safety according to the actual use conditions.Considering the fairing model of laminated shell,the fiber laying angle between the layers is different,and the failure of each layer is predicted by using the Tsai-Wu failure criterion.The results show that the fiber layer with the ply angle perpendicular to the load direction is the most prone to failure.
