Abstract

This paper is based on a previously developed bio-inspired Flapping Wing Aerial Vehicle (FWAV), RoboFalcon, which can fly with a morphing-coupled flapping pattern. In this paper, a simple flapping stroke control system based on Hall effect sensors is designed and applied, which is capable of assigning different up- and down-stroke speeds for the RoboFalcon platform to achieve an adjustable downstroke ratio. The aerodynamic and power characteristics of the morphing-coupled flapping pattern and the conventional flapping pattern with varying downstroke ratios are measured through a wind tunnel experiment, and the corresponding aerodynamic models are developed and analyzed by the nonlinear least squares method. The relatively low power consumption of the slow-downstroke mode of this vehicle is verified through outdoor flight tests. The results of wind tunnel experiments and flight tests indicate that increased downstroke duration can improve aerodynamic and power performance for the RoboFalcon platform.

关于采用变形耦合翼拍打配置的 FWAV 下冲程持续时间增加的影响的实验研究

本文基于之前开发的生物启发拍打翼飞行器（FWAV）--RoboFalcon，该飞行器可采用变形耦合拍打模式飞行。本文设计并应用了一种基于霍尔效应传感器的简单拍打行程控制系统，该系统能够为 RoboFalcon 平台分配不同的上行程和下行程速度，以实现可调节的下行程比率。通过风洞实验测量了变形耦合拍打模式和传统拍打模式在不同下冲比下的气动和动力特性，并通过非线性最小二乘法建立和分析了相应的气动模型。通过室外飞行试验，验证了该飞行器的慢下冲模式功耗相对较低。风洞实验和飞行测试结果表明，增加下冲持续时间可以改善 RoboFalcon 平台的气动和动力性能。
