Aerodynamic Damping and Dynamic Stability of Flapping Flight

本研究的目的是模拟气动阻尼对扑翼飞行的动力学和稳定性的影响，基于我们最近发现的扑翼反力矩和扑翼反力。 我们将采用实验和分析相结合的方法，包括使用动态缩放的机器人翅膀测量气动力，使用数字粒子图像测速仪进行流动可视化和测量，以及基于动力学和控制理论的数学建模。这项工作将推进科学基础，并发展动物和人造系统中扑翼飞行的综合理论。 这是首次尝试在不同的飞行条件下建立扑翼飞行动力学模型，也是解释为什么飞行动物同时具有上级稳定性和机动性的第一步。研究成果将广泛传播到生物学，物理学和工程界。 在这项工作中开发的理论可以转化为其他形式的运动，如步行，爬行和游泳。 扑翼微型飞行器的进步可以用于各种民用和国防应用。 该项目将为研究生和本科生提供一个独特的跨学科培训环境。 特别是，本科研究人员将通过普渡大学SURF和NSF REU计划参与。

The objective of this research is to model the effect of aerodynamic damping on the dynamics and stability of flapping flight, based on our recent discovery of flapping counter torques and flapping counter forces. We will undertake a combined experiment and analytical method, including aerodynamic force measurements using dynamically scale robotic wings, flow visualization and measurement using Digital Particle Image Velocimetry, and mathematical modeling based on dynamics and control theories.This work will advance scientific bases and develop comprehensive theories of flapping flight in animals and man-made systems. It is the first attempt to model the flapping flight dynamics under different flight conditions and the first step in explaining why flying animals possesses both superior stability and maneuverability. The research results will be disseminated broadly to the biology, physics, and engineering communities. The theories developed in this work can be translated into other forms of locomotion such as walking, crawling and swimming. Advances in flapping wing micro aerial vehicles can be used in various civilian and defense applications. The project will provide a unique, interdisciplinary training environment for graduate and undergraduate students. In particular, the undergraduate researchers will participate through Purdue SURF and NSF REU programs.
