摘　　要：为了探讨在总体设计中单、双尾撑布局无人机的结构效率,本文采用工程梁方法对这一设计问题进行简化与建模,作为无人机设计时对结构因素的考虑。理论推导与实际算例结果均表明,双尾撑布局比单尾撑布局具有更高的结构效率,因而从结构刚度上能够解释很多无人机采用双尾撑布局的理由。最后,作者给出了3点结论。In order to deal with the structural efficiency of UAV with uni / bi - tail - boom layout, this paper utilized the engineering beam theory to simplify and model this design problem, so that the factor of structural stiffness could be considered in the conceptual design phase. Theoretical deduction and application results showed that the structural efficiency of bi - tail - boom layout had an advantage over that of uni - tail - boom layout. That was why so many UAVs would like to use bi - tail - boom layout. Finally, three conclusions were drawn.
