Problems solved by technology

Different models correspond to different operating parameters. Although the field test is closer to the actual situation, the factors affecting the distribution of droplet deposition cannot be controlled in the field.
In the field, momentary changes in wind speed and direction will lead to changes in flight attitude, making it difficult to obtain an accurate data, and these uncertain factors make there are considerable differences between repeated experiments

Abstract

The invention discloses an indoor simulation test platform and method for spraying a two-phase flow field by a plant protection drone. The simulation test platform is used to simulate the low-altitude operation of plant protection UAVs. It can conduct indoor spraying tests of different types of UAVs at different operating heights, flight speeds and different spraying concentrations, which is convenient for studying the two phases of UAV low-altitude spraying. Flow field and spraying distribution, optimize UAV operation parameters, and specify corresponding procedures for UAV plant protection operations.

Description

technical field [0001] The invention belongs to the technical field of agricultural and forestry aviation machinery, and in particular relates to a simulation test device and a corresponding test method. Background technique [0002] In aerial spraying operations, the flying height and flying speed of plant protection drones are important factors affecting the quality of spraying. Different models correspond to different operating parameters. Although the field test is closer to the actual situation, the factors affecting the distribution of droplet deposition cannot be controlled in the field. In the field, momentary changes in wind speed and direction will lead to changes in flight attitude, making it difficult to obtain an accurate data. These uncertain factors cause considerable differences between repeated experiments. In order to determine the influence of different spraying methods or different models of nozzles on the performance of droplet deposition and drift, it ...
