Wing tip and rotor vortexes typically produce spray patterns with high peaks at what location?

Wing tip and rotor vortexes create turbulent air patterns that can significantly influence the distribution of aerially applied sprays. These vortices occur at the wingtips of fixed-wing aircraft and at the rotor tips of helicopters. As these air eddies form, they create regions of low pressure, which can draw spray droplets toward the edges of the spray pattern.

The spray pattern experiences high peaks on the edges because the turbulent air caused by these vortices tends to lift and distribute the spray away from the center. The vortex action effectively concentrates the spray, leading to a higher density of droplets at the periphery of the application area. This can result in uneven coverage and potential drift, directly impacting the efficacy of the application and the environment.

Understanding this effect is crucial for operators to optimize spray distribution and minimize unintended consequences, such as pesticide drift. This knowledge helps in refining aerial application techniques and improving overall agricultural practices.
