The invention relates to a medium-sized unmanned aerial vehicle with a high lift-drag ratio. The medium-sized unmanned aerial vehicle comprises a vehicle body, fixed wings are installed on the two sides of the vehicle body respectively, and a V-shaped empennage is installed at the tail of the vehicle body; and the aspect ratio of the wings is 17 to 19. The unmanned aerial vehicle provided by the invention adopts a high-performance airfoil profile, specific wings and empennage are designed, and good lift-drag characteristics are achieved through selection of a wing body assembly and rectification optimization of a wing body joint; and therefore, the unmanned aerial vehicle still has high lift force during low-speed flight, and long endurance time is kept.

    本发明涉及一种高升阻比中型无人机,该无人机包括机身,所述机身的两侧分别安装有固定的机翼,尾部安装有V形尾翼;其中,所述机翼的展弦比为17~19。本发明提供的无人机采用高性能翼型,设计特定的机翼和尾翼,经过翼身组合体选定、翼身结合处的整流优化,达到了良好的升阻特性;从而使无人机在低速飞行时仍具有较高的升力,保持较长的续航时间。
