Simulation and Evaluation of Wind-Induced Displacements of the Giant Airship in its Outbound Process

Abstract:

Aiming at an outbound process of the airship driven by the hydraulic rod and cables, a simulation of the wind-induced displacement for the airframe is conducted. First of all, a spatial three-dimensional flow field including the boathouse and airframe is calculated using fluid dynamics, and a wind pressure distributed on the airframe is equivalent to the forces and moments exerted on the airship head in three directions. Then, a finite element model of the airship structure is modeled and a simulation of the wind-induced displacements for the giant airship is conducted. Finally, a collision possibility between the airship and boathouse is evaluated, which lays a foundation for designing the boathouse structure that meets outbound conditions for the airship.
