| Abstract: |
| Based on the aerodynamic,the potential flow theory and the planning theory, a dynamic model of the slide jump ballistics of the amphibious UAV was developed. The slide jump dynamics characteristic of amphibious UAV had been analyzed in details, and the slide jump state had been researched on the impact of the several jumping condition. Results show that:(1)At the moment of touching water, posture of amphibious UAV changes violently and shows a intense rising trend instantaneously;(2)The angle of attack increasing will make the bedew depth increase and the slide time decrease;(3)The pitch angle increase will make the bedew depth decrease and the slide time increase. The work can give the theoretical foundation and study tools for the conceptual design, flight control systems design and flight stability assessment of the amphibious UAV. |
