Abstract
Rotary nozzles and deflectors for use with rotary nozzles are provided. The deflector includes a number of flutes that deliver fluid streams radially outwardly from the deflector. Fluid striking the flutes of the deflector cause the deflector to rotate, and the flutes subdivide fluid impacting deflector into multiple fluid streams that are distributed radially outwardly to surrounding terrain as the deflector rotates. Each of the flutes have the same curvature, although they may have different inclinations to distribute fluid streams at different trajectories. The flutes may also include blocking and downward-facing features at the ends of the flutes to improve the evenness of the fluid distribution in the irrigation coverage area.
