Abstract:
A wind tunnel tests with different configurations, pitch and yaw angles were performed to study the wind load characteristics of the rigid model of the airship Zhiyuan-1. The rigid model was aimed to simulate a technical demonstrating stratospheric airship named Zhiyuan-1 according to the similarity principle of geometric and Reynolds number. Based on the results of wind tunnel test, the features of pressure coefficient distributions on the surface of the airship were described. It was indicated that the fins and the gondola of airship hardly have the effect on the pressure distribution on the surface of airship, but have obviously effect on the local areas near the fins and the gondola.
Key words: airship, hull configuration, low-speed wind tunnel test, pressure coefficient distribution
