Today, the aviation industry is one of the essential pillars of global communication. Air transport has become an integral part of the lives of the world’s people. From air travel to the transportation of postal items and roadside and emergency services are also provided by air. In addition to the applications and benefits that airplanes have created in daily life, humans’ interest in flying should not be overlooked. For many years, humans tried to build flying wings by imitating the movements of birds and their flight type. Although these attempts often did not succeed, scientists continued to experiment and innovate. The first successful flights date back to the 17th century. In this century, humans became acquainted with the properties of different fluids as well as the properties of fluids at different temperatures. They succeeded in making balloons that used hydrogen or hot air. Despite being the first successful flights in history, these balloons faced problems such as lack of control and slow movement.

Along with experimental and creative research, science was also advancing well. A brief look at fluid flow history reveals that Navier-Stokes equations govern fluid flow. In the early nineteenth century, by solving the flow on the flat plate and obtaining the velocity profile in Navier-Stokes relationships, a huge step was taken in realizing the dream of flight. In the early 1990s, the Wright brothers built the first modern aircraft models by mounting an engine on past models. This aircraft was the first model that could fly in the air at the passengers’ will, go up and down and take the desired route. Since the creation of this model, various researches have been conducted, and improved models are being used today. Founded in 1916, Boeing is the world’s largest aircraft manufacturer. Airbus was also founded in the early 1970s by the merger of several other aircraft companies. These two companies manufacture almost all passenger planes. During the flight, the balloons were constantly affected by wind and air currents, which could be dangerous for the occupants. Among other things done to fulfill the dream of human flight, we can mention Leonardo da Vinci. Inspired by the flight of birds, he built a device that could fly from a high place and gently land on the ground. After Bineh and Bin Veno (from France) made great efforts in this field in 1678, 1884, and 1843 respectively, Hanson (from Germany), also made great efforts in this area and invented various devices that could be used from high places to throw air and land gently. These researches were the most important results in their time. These devices, in fact, are the prototypes of today’s gliders. These aircraft became known as drones. The main problems in these models are the high weight of the models produced and the lack of proper adaptation of the center of gravity and pressure. These factors made these models unable to fly well and travel long distances. Then other scientists tried to fix the existing shortcomings. In 1871 and 1896 the Frenchmen Alfonso Peno and Shano were among the first to build optimally weighted aircraft with a well-designed center of gravity.
