Abstract

Methods of modifying the water distribution pattern of
an impact-drive sprinkler are described. A method of
pattern modification called intermittent diffusion is
introduced. A deflector attached to the drive arm
intermittently diffuses the jet of a standard circular-orifice
nozzle, producing desirable pattern shapes while
maintaining a large pattern radius. Uniformity of
application for both wind and no-wind conditions was
evaluated using both the deflector and diffuse type nozzles.
The deflector is beneficial for low pressure sprinkling,
particularly under windy conditions. Equations were
developed to predict the operating characteristics of the
impact arm.
