Flow Characteristics around an Airship in Cross Flow

Abstract

The size of rigid airship model used for experiment is 1/300 scale one of the Graph Zeppelin and its overall length and maximum diameter of the section are 0.8m and 0.1m, respectively. The experiment is carried out changing yawing angle from 0 to ±90°and in Reynolds numbers 5.3×(10)^5 and 1.1×(10)^6. Effects of the yawing angle and Reynolds number on drag, side force and yawing moment are examined.
