ANALYSIS OF DEEPSTALL LANDING FOR UAV

摘要

Deepstall landing is one of the landing methods by which airplanes can decrease flight speed while maintaining a deep glide path angle. This is because the wing can generate large air drag in the deep stall state. Therefore, the method is suitable for small unmanned aerial vehicle to land within narrow areas surrounded by tall obstacles. This paper considers the trim condition in the deepstall flight phase and a numerical flight simulation from the cruise to the deepstall landing. Furthermore, flight tests were conducted to confirm the deepstall landing characteristics.
