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 equivalent force/moment of airship in variation with transport distance are ac-quired. The results shows that the turbulent flow of large factory building causes the variation of surface wind load of airship in the transport process, and the equivalent force/moment acting on airship body center show a certain degree of fluctuations; In 60 and 90 degree of the incoming flow, compared with other inflow angles, the distance affected by the turbulent flow of large factory building is shorter, the equivalent force and moment acting on the airship body center are larger, in the process of airship transport. The simulation results provide an effective reference for the safety of airship transport process.
