Design optimization of electric propulsion of flying exploratory autonomous robot

The main idea of the paper is to optimise the design parameters of the electric propulsion of exploratory autonomous robot designed for flying in specified extremely unfavourable environment. There are still a lot of unsolved needs in the flying autonomous robots area. A lack of solutions for drones flying in the unpredictable and turbulent conditions has been identified. As examples of such needs the following could be distinguished: exploration of the space-planets with their own atmosphere different from Earths or on Earth drones being used in mountain and marine emergency services which operate in extremely unfavourable weather conditions. The main ibue from the propulsion designs site is the influence of the turbulent wind, sometimes connected with precipitation on the flight mechanics. As another important concern the strength of the propulsion of the flying object can be mentioned. Another aspect which has a profound effect on the operation of such a robot drive is the best energy balance of such devices and the desire to ensure its long-Term operation and extreme maximum performance. Already, each of these tasks is solved separately and optimization is a major challenge. However, the multi-criteria optimization taking into account the coupling phenomena occurring on the robot is a much bigger problem. In the paper the requirements for the propulsion are presented and the concept solutions for specified unfavourable environments is proposed. The very definition of the abumptions of the environmental conditions defining the tasks of optimizing the yarn can be a problem. Excebively harsh conditions lead to the solutions unacceptable in practice. The following features of the conceptual drones propulsion design are analysed: aerodynamics, strength, stiffneb, mab and mobility. Consequently, the analyses lead to the optimization of the shape and design of the drones propulsion system.
