螺旋桨滑流对不同尾翼无人机气动特性影响的对比分析
Comparative analysis on aerodynamic characteristics of the UAV with different tails under propeller slipstream
摘要
Abstract
The tails often placed behind the propeller of the long endurance twin-boom UAV.In this case,the pro-peller slipstream will affect the aerodynamic characteristics.Based on the twin-boom UAV with inverted U-tail and inverted V-tail,Comparative analysis on the lift-drag characteristic and longitudinal static stability of two type UAV under propeller slipstream by numerical calculation method.The results show that when the longitudinal stat-ic stability of inverted U-tail/inverted V-tail UAV is similar,the tail capacity of inverted V-tail UAV is larger.The maximum increase of inverted U-tail UAV's drag coefficient is 36.67%,the maximum increase of inverted V-tail UAV's drag coefficient is 35.12%,the lift-drag ratio of inverted U-tail UAV is reduced by 4.14,The lift-drag ratio of inverted V-tail UAV is reduced by 4.32 under propeller slipstream,The effect of two type UAV's lift-drag characteristic under propeller slipstream are basically same.The longitudinal static stability of inverted U-tail UAV is decreases by 2.09%,The inverted V-tail UAV is decreases by 0.99%under propeller slipstream.The longitudi-nal static stability of two type UAV become worse under propeller slipstream,And the inverted U-tail UAV be-comes worse seriously.关键词
