摘要
为提高微型飞行器(M AV)的抗风扰动飞行稳定性,需要遵循仿生学原理,效仿自然界中的鸟类和昆虫,探讨抗风飞行的新方法。提出了柔性仿生机翼的概念,阐述了其设计思想与工作原理,并导出了大气扰动下柔性机翼气动力的解析表达。为验证柔性仿生机翼的实际性能,设计和制作了柔性仿生机翼M AV原理样机,并在风中进行了飞行试验。试验结果表明:采用柔性机翼能够显著改善有风条件下M AV的飞行品质,突风过载可降低40%左右,大大减弱了大气扰动对飞行的影响,有效提高了M AV的飞行稳定性。
To improve the flight stability of micro air vehicles （MAVs） in the wind, the vehicle designs should mimic birds and big insects, using bionics concepts to design new control methods. This paper describes a flexible bionic wing, with a theoretical model to describe the working principle for the aerodynamics in wind gusts. The fligbt performance of the flexible bionic wing was tested using an MAV in various weather conditions. The test flights validate tile effectiveness of the flexihle bionic wing, which reduces the influences of gusts and turbulence in the atmosphere by 40 percent to improve the flight characteristics on windy days and effectively enhance the flight stability.
