Abstract

he concept of specialized training unmanned aerial vehicle (UAV) of aircraft type for operators of unmanned aerial vehicles is proposed. Training opportunities in various areas of operator training are highlighted. A method of manufacturing an aircraft-type training UAV taking into account aerodynamic and weight characteristics has been developed. The developed method is based on the production of aircraft parts using a 3D printer, which is modified to meet the requirements of small aircraft type aircraft. This technique also includes the process of selecting the most advantageous combination of materials to create a small aircraft. Tables with initial data of existing UAVs are given.The flight characteristics, aerodynamic schemes and type of engine that are most rationally suitable for unmanned aerial vehicles in accordance with this class are proposed. Based on these data, a prototype model was built, the method of UAV design was adopted, taking into account the choice of parameters of the power plant. A demonstration example of the choice of the main parameters of the training taking into account the UAV under specific requirements is given. The obtained main technical characteristics of the UAV are presented. Based on the calculated data, a three-dimensional geometric model of the UAV was developed and a flight sample was made. A series of test flights of the flight model was conducted, tested under difficult weather conditions, when the wind force is about 12 m / s. The ways of using the described method of developing UAV training and research, as well as many other factors that affect 3D printing without detecting defects and problems are considered.
