Multi-mode design models of non-linear straining of depressed shells during their supersonic gas flow have been structured. Small starting flexures complicate a shell model. The system of four non-linear differential equations obtained by a method of Bubnov-Galerkin on the base of which joint influence on shell stability and oscillations of gas flow and geometric irregularities can be investigated.
