For unmanned aircraft for transportation purposes, the key issue is the choice of characteristics of lifting thrusters, which should have sufficient efficiency at limited dimensions. In this paper, the methodology of numerical modeling of propeller ring thrusters, propellers rotating in a ring, is sequentially considered. The characteristics of propellers with propellers differing in the number of blades, geometric twist of blades, degree of coverage of the area swept by the propeller and blade
