Abstract

Consideration of geometric nonlinearities is important in the static and dynamic design of nonrigid airships. The finite-element method, using MSC/NASTRAN, is applied to perform linear and nonlinear static analyses and to determine the free vibration characteristics of such airships. It is found that the solutions obtained using the linear plus differential stiffness matrix may be quite adequate for airship structural analysis. A procedure to design a wrinkle-free catenary curtain is presented. The necessary solution sequence alterations used to determine the natural vibration characteristics of airships using MSC/NASTRAN are presented.
