飞翼类特殊布局无人机气动力设计研究

摘要

文章针对飞翼布局无人机的气动力设计特点,结合某特殊布局方案开展翼型/机翼气动力设计研究.根据文中提出的无尾飞翼布局无人机气动力设计原则,基于CFD方法完成了相应的气动力设计任务.风洞验证试验表明,气动力设计过程所采用的CFD方法是可靠的,文中所采取的设计思路合理有效.文中设计经验表明,合理的设计思路与可靠的CFD分析工具是成功实现气动力设计任务的有力保障.%Sections 1 through 4 of the full paper explain the layout design mentioned in the above title. Section 3 is entitled "aerodynamic design of airfoils" ; it is divided into subsections 3.1 and 3. 2. Section 4 is entitled "aerodynamic design and performance of wing" ; it is divided into subsections 4. 1 and 4. 2. Wind tunnel test results and simulation results, both presented in Figs. 3 through 5 and Table 1, and their analysis show preliminarily that the aerodynamics design methods and CFD tools used in this paper are suitable for airfoil and wing layout design of flying wing UAV.
