As an important part of the wing, skin deformation accuracy directly affect aerodynamic performance aircraft in different environments. Based on idea easy processing and deformation, a method for designing variable section thickness trailing edge camber wings is proposed. In this paper, firstly, length each segment 3~8 segments are optimized. Then results compared analyzed. Finally, correctness...

Abstract Carbon fiber reinforced plastic (CFRP) laminates are often used in a quasi-isotropic manner, such as cross-ply lamination; thus, the mechanical properties of CFRP cannot be fully exploited. In this study, we proposed carbon design method, which uses orientation and thickness lamination parameters, where is determined using principal stress direction by iterative calculations maximum th...

In this paper, a novel variable stiffness mechanism (VSM) based on specially designed S-springs made from shape memory alloy (SMA) is developed. Based the model, by changing state combination of SMA with different thicknesses, actuator's can be discretely adjusted online. The adjustment range actuator conveniently extended almost 0 N/m to infinity preset spring angle manually offline without co...
