Abstract

The invention discloses an indoor simulation testing platform and method for a two-phase flow field of spraying of a plant protection unmanned aerial vehicle. The indoor simulation testing platform comprises a console, a simulation device, a fog drop distribution detection and/or wind field detection device and the like. The indoor simulation testing platform is used for simulating low-altitude operation of the plant protection unmanned aerial vehicle, and can conduct indoor pesticide application tests through different unmanned aerial vehicles under the conditions of different working heights, different flight speeds and different spraying concentrations, and therefore research of the two-phase flow field and spraying distribution of low-altitude pesticide spraying of the unmanned aerial vehicle is facilitated, operation parameters of the unmanned aerial vehicle are optimized, and the corresponding procedure is assigned for plant protection operation of the unmanned aerial vehicle.

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 ...
