ResumenThe use of rotating spray plate sprinklers (RSPS) can reduce the water and energy requirements in pressurized irrigation systems. Installation of RSPS in continuous move irrigation machines, such as traveling trailers (nozzle booms), presents relevant advantages compared to sprinkler-gun machines. The aim of this study is to develop design criteria for continuous-move irrigation machines using the RSPS Nelson Rotator R 3000 D-4. Water distribution by this RSPS was evaluated in an indoor facility under the following experimental conditions: 6.1, 7.0, and 7.8 mm nozzle diameters; 1.0 and 1.5 m nozzle height above the ground; and working pressures of 100, 150, and 200 kPa. The water distribution patterns were overlapped at 3 and 4 m distances, the simulated Christiansen uniformity coefficient averaged 91.8%, and the simulated average precipitation rate under the different experimental conditions ranged between 23 and 57 mm·h-1. These values are acceptable for a wide range of irrigation-machine applications.
