摘要
参考国内外充气式机翼的研究成果,介绍了充气式机翼的结构设计方法,运用CFD技术对充气式翼型和原常规翼型进行了升阻特性和流场特性的比较研究,利用ABAQUS对充气式机翼进行了弯扭和应力方面的计算分析,最后创建了充气式无人机的三维模型,并进行了无人机的飞行试验。验证了充气式机翼在实际使用中的可行性。
According to the research of the inlfatable wings at home and abroad, a designing method about the inlfatable wings was introduced, combining with practical experience. A comparative study about the lift-drag characteristics and lfow characteristics of the inlfatable airfoil and the original airfoil were proposed using CFD. The computing and analysis about the bending and stress of inlfatable wings were conducted using ABAQUS. Finally, a three-dimensional model of the inlfatable UAV was created. And the production and lfight test about the UAV were conducted. All of these verify the feasibility of the practical use of the inlfatable wings.
