| Abstract: | The report presents aerodynamic properties of the tethered balloons in the natural and streamlined shape at some fixed altitude and puts emphasis on exploration of the effects of angle of attack and Reynolds number on lift, drag and pitching moment of the balloons. A reasonable and excellent aerodynamic configuration with the reliable stability and minimum drag is significant for strengthening the capability against the gust and pro1onging the operation time at such a high altitude. |
