Nonlinear analysis of airship envelop aerolasticity
This paper aims at the numerical simulation of nonlinear airship envelop aeroelasticity by means of coupling aerodynamics and structure using an iteration method. The three-dimensional flow around the airship is studied numerically with the method of SIMPLE based on the Finite Volume Method. Two approaches, linear and nonlinear, are introduced for the geometrical deformation of the airship shape. Comparison of aerodynamic parameters and the pressure distribution between rigid and aeroelastic models is conducted when an airship is in a trimmed flight state in specified flight conditions. The effect of aeroelasticity on the airship aerodynamics is detailed.
