Seeds on a parachute: the technology of greening

Abstract

Abstract To strengthen the sides of tailing dams and stockpiles, it growing forests from trees, shrubs and plant grass. Due to the difficult topography of the terrain, greening technologies require new ideas and material support. The objective of the research is to develop a technology for sowing large areas of plants with seeds from the air. In order to sow large areas with plants, it proposed to scatter seeds (grains) from a height onto hard-to-reach slopes, attached to a parachute system of a special design. Thousands of swarms of miniature capsules with seeds lifted by the drone and released by it at a given height will be scattered by the wind over large cultivated areas. The capsule filled with grain, fertilizer, humus and a compartment with water (gel). The parachute system is a three-dimensional paper platform that allows the capsule attached to it to fall smoothly and slowly. The hooked plumage of the platform provides its reliable grip on the ground. The platform is also soaked with seed nutrients before launch. Analytical, computational and experimental studies have confirmed the highly efficient aerodynamic properties of the developed parachute systems. 3D flying platforms demonstrated controlled rotation kinematics (18 rad/s) and low final speeds of 1.6-1.9 m/s.
