In the article, proceeding from the agrotechnical demands, optimum boundary lines of target hydraulic parameters of a water system and motion characteristics of an irrigating jet of a drum-type sprinkler are determined. Formulas-determination of a jet range and heights are obtained in view of the position of the sprinkler above the earth surface. A graphical interpretation of the dependences connecting hydraulic and kinematic parameters is given. The analysis of the structure and power parameters of a formed artificial rain is made. It is shown that at constant values of flow rate irrigation radius the magnitude of a layer of a rainfall is a function of a speed. It is established that the high-quality artificial rain for a range of values of nozzle diameters 21.1–27.5 mm will be gained at a pressure of no less than 54.98 m and flow rate of 39.26–66.68 m3/.(at a rain intensity of 0.29–0.35 mm/min, respectivel
