摘要

Recently there has been significant interest in the development of unmanned aerial vehicles (UAVs) for civilian, military, and space applications. However, one of the limitations to the widespread adoption of UAVs, is their inability to perform well in gust-laden environments. This research adopts a bio-inspired approach to improve UAV designs by studying the aerodynamic response of a red-tailed hawk exposed to vertical gusts. To study the aerodynamic response of birds in a controlled environment, a flight arena was developed by using industrial fans to produce an average velocity of 6.5 - 8.5 m/s. This gust region was introduced in the flight path of the red-tailed hawk. Hawks normally fly at 10 - 18 m/s, making the gust magnitude approximately half of the hawk's flight speed. MATLAB DLTdv7, a digitizing software, was adapted and implemented to track specific points on a flapping-wing UAV. Using this procedure and high-speed camera images, the beak and the tail of the red-tailed hawk flying through a vertical gust was tracked to study the pitching response of the hawk to vertical gusts. This paper discusses the methodology implemented to track the kinematics of a UAV and its application to measure the hawk's response to a vertical gust that is introduced over the entire wingspan of the hawk.
