摘要: 扇翼飞行器是一种新概念新原理飞行器,尤其是其具有独特空气动力学原理。扇翼能够同时产生升力和推力,为了进一步改善扇翼的气动特性,在不改变扇翼基本几何参数的前提下,沿机身纵向布置前后2个扇翼,组成了纵列式双扇翼飞行器。通过数值模拟的方法,计算了前后扇翼间距、高度和安装角变化时的扇翼升力和推力值,分析了前后扇翼气动特性相互影响的规律。此外还设计了纵列式双扇翼的风洞试验模型,将获得的风洞试验结果与数值计算结果进行了初步的对比验证。结果表明,在一定前后扇翼间距、高度和安装角下,纵列式双扇翼的气动力相比单个扇翼更具优势。因此,纵列式双扇翼布局的飞行器具有很好的发展前景和应用优势。

Abstract: Fan wing aircraft is a kind of new-concept new-principle aircraft, and especially its wing has unique aerodynamic principle. Fan wing can simultaneously generate lift and thrust. In order to further improve fan wing's aerodynamic characteristics, two fan wings were installed along the longitudinal body without changing fan wing's basic geometric parameters, which is composition of a tandem fan-wing aircraft. Through numerical simulation, the lift and thrust of the fan wings were calculated with the change of distance, height and installation angle of the front and rear fan wings, and the interaction rule of the aerodynamic characteristics between the front and rear fan wings was analyzed. In addition, the wind tunnel test model of a tandem fan wing was designed, and the wind tunnel test results and numerical calculation results were compared and verified preliminarily. The results show that in a certain condition of height, distance and installation angle, the aerodynamic characteristics of tandem fan wing have more advantages compared to single fan wing. Therefore, a tandem fan-wing aircraft has good development prospects and application advantages.

Key words: fan wing, cross flow fan, aerodynamic characteristics, wind tunnel test, CFD
