Проектирование рамы автономного летательного аппарата с применением композиционных материалов

Abstract

The paper considers approaches to creating a new type of unmanned aircrafts - quadcopters. It is stated that the efficiency of a quadcopter directly depends on its frame design and the structural materials used. The approaches to designing the aircraft frame using computer-aided design tools (SolidWorks package) are described. The stress maps obtained during the strength study for the frame beam made of carbon fiber allow asserting a large margin of structural strength. The strength calculation carried out predetermined the need to take into account the influence of additional factors (the air flow created by the traction screws). The existing restrictions on the maximum size of the rotating propellers predetermined the design of the quadcopter frame taking into account the maximum number of possible aerodynamic effects that determine the stability of flight characteristics by minimizing interference from air turbulence, as well as from possible natural phenomena. The designed quadcopter frame has special aerodynamic surfaces that allow for a stable flight path in a volatile air environment. The generated torque is determined by the characteristics of the traction screw motors. The influence of the isosurface air flow on the design of the quadcopter was evaluated.
