N2 - The paper presents a computational technology for optimization of composite overwrapped pressure vessels (COPV). Mathematical modeling and numerical optimization were applied to design COPV. The mathematical models were built using different shell theories and structural models of composites. The stress-strain state of the vessels was determined and analyzed based on three mathematical models. Several solutions of COPV optimization problem based on different problem statements were obtained. They were analyzed and verified by substituting of the estimated design parameters in a direct problem of stress-strain state determination. The study demonstrated that using of non-constant design parameters, such as the thickness, the winding angle and the curvature radius of the composite shell gave the possibility for additional reduction of COPV mass, while keeping its strength. In addition, acceptability and convenience of using simpler mathematical models for numerical solving the optimization problems were demonstrated.
