A spreader device for an aerial vehicle comprising:
- a hopper axially mounted above a generally circular hollow tube, the generally circular hollow tube forming a semi-circular hopper floor of an interior area formed by the hopper;
- a drive motor assembly attached to the hopper and operable to rotate the generally circular hollow tube within at least a portion of the interior area formed by the hopper;
- wherein a height of the aerial vehicle, a speed of a rotation of the hollow tube, a speed of travel of the aerial vehicle, and a propeller airstream of the aerial vehicle create a distribution pattern for one or more contents within the hopper as the spreader device spreads the one or more contents of the hopper outside of the interior area of the hopper;
- and
