Aeroelastic tailoring method of tow-steered composite wing using matrix perturbation theory

In this study, a computational method based on matrix perturbation theory was proposed to solve the aeroelastic sensitivity of the fibre angle of tow-steered composite wings and find the optimal local fibre paving path for aeroelastic tailoring. Firstly, the finite element model of straight fibre composite wing was created with the multilayer composite shell element in MSC/NASTRAN. Then, the flutter velocity-sensitive region with local fibre...
