Experimental study on the stability properties of different design of tandem wing airship models

摘要

This paper introduces a set of new design for the tandem wing airship, which the angular position between the front wing and tail wing are at 0° and 45°. Through the Wind Tunnel Platform test on the scaled models, lift-drag force for each configuration at different speed and mooring point was obtained and the aerodynamic performance and stability properties were analyzed. The results indicate that the tandem wing models have considerable higher aerodynamic characteristic and maintain a better stabilizability. The effect on longitudinal and yaw moment are relating to the mooring point and angle of the tandem wing. Result of this study could provide a new approach in designing an efficient tandem wing airship.
