This publication addresses the proposed structural solution for a system, of which the conceptual essence involves a rescue parachute being ejected from an accumulator using compressed carbon dioxide. The suggested rescue system is intended for unmanned multicopter aircraft. The article presents a developed digital solid model and the results of its simulation tests. The paper also contains results of basic calculations of the pneumatic supply system energy balance and the power balance of the
