1. A deflector for an irrigation nozzle comprising:
an underside surface including a plurality of flutes contoured to cause rotation of the deflector about a central axis when a fluid impacts the underside surface and to redirect the fluid away from the underside surface in a plurality of streams;
each of the plurality of flutes comprising:
an inlet end;
an arcuate inner portion having a radius of curvature extending from the inlet end, the inlet end having a lateral offset distance from the central axis and the arcuate inner portion starting at the inlet end, the radius of curvature and the lateral offset set to provide torque to rotate the deflector when the arcuate inner portion is impacted by the fluid; and
a linear outer portion extending to an outlet end and having an exit offset distance relative to an imaginary parallel radial line extending outwardly from the central axis;
wherein when the lateral offset distance is increased and the radius of curvature is increased, the exit offset distance remains the same to straighten an overall profile of the flute.
