为研究具有柔性气动外形的微型飞行器抗气流扰动特性,本文设计了一种具有柔性气动外形微型旋翼飞行体,利用有限元方法对飞行体垂直气道的设计模型进行了模态分析,实现了飞行体的垂直起降和悬停。在基于双目立体视觉测量的气流扰动场实验装置中对飞行体完成初步的三维可视化检测,利用频闪成像方法记录气流扰动下飞行体的运动轨迹和气动外形的形态学变化,为研究柔性气动外形非定常气动特性以及飞行体抗扰动机理提供一种有效的可视化信息提取方法。
In order to study the anti-airflow disturbance characteristics of a micro-aircraft with a flexible aerodynamic profile, a flexible aerodynamic profile micro-rotor flying body is designed in this paper. The finite element method is used to analyze the design modal of the vertical airway of a flying body, Body vertical takeoff and hover. In the air disturbance field experiment device based on binocular stereo vision measurement, a preliminary three-dimensional visual inspection of the flying object is completed. The stroboscopic imaging method is used to record the trajectory of the flying object and the morphological changes of the aerodynamic profile. Unsteady aerodynamic characteristics and the anti-disturbance mechanism of the flying body provide an effective visual information extraction method.
