Abstract
The problem of experimental research of the parameters of the propeller-motor group of an unmanned aerial vehicle (agrodrone) is considered. An analysis of the work performed by agrodrones in agriculture, as well as popular serial models of agrodrones produced by well-known global companies, including in the Republic of Belarus, has been carried out. A description of the design of the experimental stand, specially designed for testing the operation of the agrodrone power plant under conditions as close as possible to the real operating conditions in which the agrodrone has to operate, is given. The main structural elements of the test bench and measuring instruments that are used to conduct experimental studies of the operation of the propeller and its electric drive are described. The results of the research are presented in the form of quantitative values of the vibration parameters of the propeller-motor group of the agrodrone at given values of the input parameters of the electric drive control system, taking into account the influence of external factors. It is shown that the values of the parameters characterizing the vibrations of the propeller-motor group of the agrodrone can be different depending on the operating modes of the engines and changes in external conditions. Based on the results obtained, it was concluded that when formulating the mathematical formulation of the modeling problem, it is necessary to take into account the influence of random factors on the control system of the agrodrone, including vibrations caused by the operation of the agrodrone engines.
