鸭翼纵向位置对飞行器气动特性的影响

分析了鸭式布局飞行器的气动力矩特性，通过风洞实验研究了两种纵向位置不同的鸭翼在不同马赫数及迎角状态下对飞行器气动特性尤其是滚转特性的影响．实验结果表明，鸭翼、尾翼面间距大小对飞行器的滚转特性有较大影响，随着鸭翼纵向位置的后移，减小了尾翼上诱导的反向滚转力矩，滚转控制效率提高，且使飞行器静稳定性增强，但鸭翼位置的后移对飞行器升力特性影响甚微．

Research of Aerodynamic Characteristics on Canard Configuration Air Vehicle with Different Canard Position

This paper discusses the moment characteristics of canard configuration. Two different positions of canard configurations are adapted at different speeds and attack angles with wind tunnel test. The results indicate that the rolling characteristics are great affected by the distance between canard and tail. With the longitudinal position of the canard moving backward, reverse rolling moments are induced and rolling control efficiency is increased. Static stability of air vehicle is improved. But, the lift characteristics are little affected.
