| Summary: | 碩士 === 淡江大學 === 機械與機電工程學系碩士班 === 93 === The research of micro aerial vehicles (MAVs) is a new field, which attracts much attention in the advanced aeronautical area. The flapping wing, proved by many natural flyers, is the most appropriate way of flying objects with size less than 6 inches. However, there is still plenty of room for studying on the unsteady aerodynamic characteristics of flapping wings. The flapping wing, which is light weighted and high strengthened, is composed of a titanium-alloy frame and a parylene skin in this study. Such an integration of fabrication needs the help of MEMS processing.
In the wind-tunnel experimental, the signals from a load cell in the wind-tunnel and the PVDF sensors embedded in parylene wings are acquired simultaneously. Both of the lift signals from the PVDF and the load-cell are basically identical with the same flapping frequency and with the similar qualitative behaviors.
Finally we integrate Li-battery into our MAV system and perform test fly of the MAV prototype. The longest distance which our MAV system can reach is 10~15m so far.
