Abstract:

With the development of technology, the usage rates of unmanned aerial vehicles have increased. Although unmanned aerial vehicles were first used as counter-attack in army, they were also used for surveillance, reconnaissance, mapping and defence. In addition to this, have begun to be used for various purposes such as taking images from the air in the film industry, carrying cargo, traffic control, natural disaster search and rescue, fire warning and extinguishing, illegal building control. While the advantages of fixed wing unmanned aerial vehicles are that they can move quickly, the disadvantages is that long runways for take-off and landing. Rotary wing unmanned aerial vehicles have the advantage that they do not need runways because they can take off and landing in the same place, but they are disadvantageous because of their low flight time. The general name of the rotating wing unmanned aerial vehicle is drone. 4 propelled quadcopter and other multi-propelled multicopters are inefficient in energy management, 2 propelled bicopters are less manoeuvrable, tricopter is more advantageous than others. The tricopters have better maneuverability than other rotary wing aircraft thanks to the servo mechanism used in the tail motor. Tricopter’s fixed body (moment arm of the rotor) which are endurance, ease of control, ease of to-downstream keeps constant the air vibrations and like many features stable flight. By using innovative tricopter aerodynamic mechanism, the torque arm of the rotors is provided with variability and performance/stability parameters are planned to be stabilized and kept in the air for a long time.
