Abstract. In the article a new three-dimensional mathematical model describing the deflected mode of the composite orthogonally anisotropic detail elastic section of spacecraft is presented. The developed system of partial differential equations taking into account the deformation of transverse shifts arising when the deflected mode of the composite construction changes is designed for the forecasting of the shapes and parameters of the oscillations of bulky thin-walled detail elastic sections, which are subjected to the exposure of mechanical and temperature loads at the stage of the flight operation of spacecraft.
