摘要
Abstract
The variable-sweep aircraft can meet the aerodynamic requirements under different flight conditions,but the skin needs to meet the large deformation and aerodynamic load requirements during the deformation process.In this paper,based on the variable parallelogram mechanism,a shear variable sweep wing was designed and manufactured firstly.Then,a composite skin structure based on unidirectional fiber reinforcement is proposed rubber materials and fiber-reinforced rubber materials were selected as the research objects of flexible skin,and a constitutive model of skin deformation was established.Numerical simulation analysis and shear deformation experiments were carried out on the flexible skin.The wing designed and manufactured in this paper can realize the function of shear-variable sweepback;When the flexible skin is deformed in shear,the experimental results are in good agreement with the numerical simulation results;The fiber-reinforced rubber flexible skin has better resistance wrinkle and load-bearing capacity.关键词
