Опис руху безпілотного транспорту літакового типу

Unmanned vehicles are now used in most areas of our lives, from entertainment and education to military and rescue. Each of these areas has certain requirements and criteria for the vehicle they need: for entertainment, the simplest design that can fly is sufficient; for science, it is more complex vehicles that are needed to collect certain data; for the military, vehicles that can not only conduct surveillance and monitoring but also have the ability to hit the necessary targets; for the rescue sector, it is the type of vehicle that will be able to deliver goods and transport people. Given the need for unmanned vehicles, the relevance of developing new and improved types is extremely high. The subject of research in this article is unmanned aircraft-type transport. The purpose is to calculate and describe the movement of an unmanned aircraft-type vehicle under design. The paper presents the most common conceptual types of unmanned aerial vehicles. Taking into account the conceptual types, the airplane type is considered as the basis for design. A coordinate system for analyzing the movement of aircraft is proposed and presented. The method of Lagrange's equations of the second kind is chosen to compile mathematical models of aircraft motion. The kinetic energy of a complex body performing a complex motion is considered and calculated; for this purpose, calculations are carried out in absolute motion using absolute linear and angular velocities. The selected angles used for the calculations are demonstrated. The moment of inertia about the instantaneous axis is considered and the equation of kinetic energy of rotation about the axis is derived. The calculations were used to find the limits of angle change. The data obtained are necessary for further calculations, such as determining the focus of the aircraft by angle of attack, determining the derivative of the fuselage lift coefficient by angle of attack, and all further calculations related to the proposed angles. The considered approach makes it possible to forecast the flight plan taking into account energy consumption and allows calculating the required amount of energy to perform the task.
