MATHEMATICAL MODEL OF MOTION OF A MULTIROTOR UNMANNED AERIAL VEHICLE

Background. Unmanned aerial vehicles (UAV) are widely used in present-day reality. When developing UAV new models, solution of both design-and- appearance and program-algorithm problems such as, for example, control and navigation algorithms has to be found. Materials and methods. In development of the UAV a mathematical simulation is commonly used. Mathematical simulation enables studying of the UAV’s operability both in routine mode and in emergency without producing UAV physical model. Results and conclusions. The article proposes a mathematical model of multirotor UAV using a quadcopter as an example, basic aspects of the multirotor UAV aerodynamics are set forth, equations of centroidal motion and motion around mass-center of a quadcopter are handled.
