Aiming at the problem that the stability of airship’s posture is destroyed by turbulent flow when the airship leaves the large factory building, a Computational Fluid Dynamics (CFD) numerical simulation method is used to simulate the condition that airship transport process in different angle of the incoming flow, and the surface wind load and equi...

Context 1
... main parameters of the Lotte-airship are as follows: The hull length L=16m, the maximum diameter D max =4m, the volume of airship V=109m 3 , the slenderness ratio L/D=4, the empennage is a cross configuration. The 3D simulation model of airship is shown in the Figure 2. Considering the blocking rate and the full development of the flow, the distance between the outflow boundary of the computational domain and the airship should be more than 10 times of the airship height. ...

... the post-processing software, the distributed wind pressure on the airship surface is equivalent to the resultant force and moment acting on the airship body center along the x, y, z axes, and the change of resultant force and moment of airship in different incoming flow directions can be gotten, as shown in Figure 14 to Figure 27.
