RESEARCH OF THE BASIC AERODYNAMIC PARAMETERS OF THE UNMANNED AIRCRAFT PLANER OF CONVERTOPLAN TYPE
R.N. Nabiyev, A.A. Abdullayev

Development of aircrafts (AСs) directly depends on the ratio of energy and weight, power and propulsion systems of the glider to the overall dimensions, aerodynamic properties of the wing, as well as the aerodynamic quality ratio of the wing of AC. The energy consumed during the flight directly depends on the quantity indicating how many times the coefficient of lifting force created by the wing is greater than the coefficient of opposite resistance force depending on the shape of the wing selected for the AC and the angle of attack, and during projecting it is required to use the construction that allows energy saving during flight time of the AC. It is also important to take into account the aerodynamic properties of the wings and to solve the issues of stability regulation when designing the AC. The listed problems to be solved are most often reflected in unmanned aerial vehicles (UAVs). In order to ensure long-term flight of UAVs, they already try to use moving rotating wing technology and different types of engines parallel to the vertical and horizontal planes. Each of these technologies has its advantages and disadvantages.
Keywords: unmanned aerial vehicle, convertiplane, glider, flying wing, aerodynamic features.
