Methodological support for the training of UAV designers and operators

Abstract

In this paper, we presented the developed concept for end-to-end training of designers and operators of UAVs on the basis of the use of specialized aircraft-type trainers. The educational possibilities of the concept in terms of various training programs are discussed. A methodology for the selection of the main parameters of UAV taking into account the mutual effect of aerodynamics and weight was developed. It provided a wide range of specific requirements for UAVs for acquiring initial control skills in manual and automatic modes. The developed methodology is based on the takeoff-weight buildup equation modified with regard to the specific requirements for small-sized vehicles. This methodology also includes the process of choosing the most advantageous combination of geometric and kinematic parameters of an aircraft propeller using the isolated blade element theory. The methodology is implemented in PascalABC.NET language. A demonstrative example of selecting the main parameters of a training UAV for specific requirements is presented. The obtained basic technical characteristics of the UAV are given. A three-dimensional geometric model of the UAV was developed on the basis of the calculated data, and a prototype was manufactured. The flight parameters recorded through a series of test flights of the prototype are presented. The ways of using the described methodology for the development of training-and-research UAVs are discussed.
