The technique suggested is based on the union of several groups of numerical simulation problems while solving problems related to statics and mechanical system motion under the influence of external forces. Analyses of structures made of composite materials and of light rotorcraft control system mechanisms are given as examples. Possibilities of the application of nonlinear problem solutions at the early stages of aircraft design are considered. Construction of solution algorithms of design problems is based on the mixed application of calculation software of Russian and foreign development.
