Investigating selected methods to improve aerodynamic coefficients and better performance of UAV

An unmanned aircraft (UAV) is a type of aircraft that operates without the need for a human passenger. These planes are able to fly automatically, without the need for remote control, and are mostly controlled by computers and sensors. UAVs are used in many industries and have various applications, including communications, surveillance, aerial photography and videography, security and border surveillance, search and rescue, scientific and environmental studies, agriculture, as well as the military industry. The advantages of using UAVs include high efficiency, access to difficult and dangerous areas, and cost reduction. However, the use of UAVs also comes with challenges and problems. One of the most important problems is the risk of losing control, aerodynamic problems, and running out of fuel at different angles of attack. Improving aerodynamic coefficients can help increase flight safety and reduce risks related to losing control of the aircraft. In this research, we examine the elements, changing the shapes created on the airplane wing, and applying control surfaces to improve the aerodynamic coefficients.
