We propose the model of the dynamic behavior of solid propellant motor composite casing under the internal impact
pressure. This pressure describes the operation of the engine. The thin-walled casing consists of the cylindrical shell and two bottoms in the form of truncated hemispheres. The casing is clamped to the rocket along two edges of the bottoms. The structure model takes into account the shear, the rotary inertia and the stress-strain relations for the orthotropic material. The semi-analytical method allows analyzing the stress-strain state of the structure. In the model, the thin-walled casing dynamic is described by high dimension system of the ordinary differential equations.
