应用结构力学和材料力学的相关理论分析了一种充气机翼的承载能力,基于充气机翼特性和工程要求分析,确定了充气机翼失效的条件,建立了充气机翼弯曲变形的力学模型,并通过试验验证了该模型的合理性;然后,利用FLUENT 6.3对该种充气机翼翼型进行了气动特性仿真分析,并与相应的标准翼型进行了对比.最后,将三维充气机翼的气动载荷仿真数据导入Patran,对充气机翼在飞行状态下的应力和变形进行了有限元分析.
Based on the theory of structural mechanics and material mechanics, the bearing capacity of an inflated wing is analyzed. Based on the characteristics of inflatable wing and the analysis of engineering requirements, the failure conditions of the inflated wing are determined, and the mechanical model of inflated wing is established. Then the aerodynamic characteristics of this airfoil were simulated and analyzed by FLUENT 6.3 and compared with the corresponding standard airfoils.Finally, the aerodynamic performance of the three-dimensional airfoil The load simulation data was imported into Patran, and the finite element analysis of the stress and deformation of the inflatable wing under flight condition was carried out.
