摘要
为了提高飞翼布局无人机的起降气动特性,引入了一种新颖的低速控制装置——腹襟翼。基于CFD技术研究了腹襟翼对飞翼布局无人机低速气动特性的影响,并对腹襟翼安装位置,偏角和实度参数进行了气动优化设计研究。经过优化设计的腹襟翼能够大幅提高无人机起飞离地迎角的升力系数和俯仰力矩系数,能够提高无人机的起降气动特性。
In order to improve the takeoff and landing aerodynamic characteristics of flying wing unmanned aircrafts, a novel low speed control device called the belly-flap is introduced. Low speed aerodynamic characteristics of the flying wing unmanned aircraft is studied by using CFD. The aerodynamic optimization design on the locations, deflection angles, and solidity of the belly-flap is carried out. The lift-off lift coefficient and moment coefficient are increased by the help of the belly-flap, and the takeoff and landing aerodynamic characteristics of the unmanned aircraft are improved.
