“…İHA kullanımıyla birlikte daha rahat ilaçlama ve bitkiye ulaşım sağlanmıştır. Fakat hava araçlarındaki taşıma kapasitesi sınırlıdır ve bu araçların aktif kullanım süreleri azdır (Ay & Ince, 2015). Bunlar artırılabilir fakat bu sefer de maliyet ciddi oranda artacaktır.…”

“…Bunlar artırılabilir fakat bu sefer de maliyet ciddi oranda artacaktır. Kullanım süresi ve taşıma kapasitesinin yanı sıra tarımda kullanılan genel bir İHA'nın bir kara aracına göre fiziksel dayanımı düşüktür (Ay & Ince, 2015). Ayrıca havanın rüzgârlı olduğu günlerde hava aracının kullanımı pek mümkün olmayacaktır ve havadan sıkılan zirai ilaç bitkiye ulaşmadan dağılabilir.…”

Engineering is the use of scientific principles to design and construct machines, structures and other items, including bridges, tunnels, roads, vehicles and buildings. The engineering discipline encompasses a wide range of specialized engineering fields, each with particular emphasis on specific areas of applied mathematics, applied science, and application types. Engineering is a sub-discipline created by the interdisciplinary partnership that plays a very important role in the development and development of a country. Engineering is a profession that develops economical methods to present the forces and substances of nature for the benefit of human beings, using the knowledge gained through study, experimentation and application from the branches of mathematics and natural sciences wisely. Because the engineering approach; It is the human approach whose job is to solve problems. Employees who take the engineering approach know how to see the unseen, find the unthinkable, target optimum solutions and get the maximum benefit from the situation. On the other hand, although a very broad and detailed definition comes to mind with the question of what is engineering, we can say that engineering is the application of science and mathematics necessary to solve problems. Engineers understand how things work and find ways to use scientific discoveries in practical life. This book published; It was created from the presentations of both their own original studies and compilation studies from the literature presented by academics who teach in various engineering branches. The aim here is for engineers and academics interested in the subject to find important engineering studies together. Therefore, I believe that the book will fill an important gap and be useful to young researchers. In this context; We would like to thank everyone who contributed scientifically to the book, in short, who contributed to the preparation of the book for printing. I hope that this published book will be useful to both engineers and young academics, and I wish success to all engineers and young academics.

Various standard airfoils are used in aviation, wind turbine blade designs, and for other applications that rely on aerodynamic forces. The rapid evolution of computing methods now allows you to accurately calculate the flow behavior of the airfoil in the short term. In this study, the aerodynamic performance of the NACA 63-215 and NACA 65-421 standard airfoils created by the National Aeronautics Advisory Committee (NACA) was analyzed with two-dimensional computational fluid dynamics. These analyses were performed on a 1 × 106 Reynolds number and at different attack angles to discover better aerodynamic performance. Spalart-Allmaras, the standard k-ε and standard k-ω turbulence models are evaluated comparatively based on experimental data. Finally, the results and comparison of various properties i.e., drag and lift coefficients, pressure distribution over the airfoils are presented to help the user choose the right airfoil, and the turbulence model for a wing design or other aerodynamic modelling corresponds.

“…Multi-rotor Unmanned Aerial Vehicles (UAVs) specialized for plant protection have commonly used in agriculture throughout the world, especially in China [1,2] , and pesticide spray is one of their key functions. A large amount of research focused on the distribution of droplets during UAV operation [3][4][5][6][7][8][9][10] , like testing UAV performance and finding out optimal parameters for operation. For instance, Liao et al examined three kinds of UAVs, including a four-rotor, a six-rotor and an eight-rotor UAV, to obtain their spray swath and uniformity.…”

Currently, Computational Fluid Dynamics (CFD) has been used to investigate agricultural UAV downwash. However, the validations of CFD models are difficult to deal with. Current verification methods are to use either water-sensitive papers or wind-speed arrays, which could get wind distribution or speed only. In this study, model migration was used to develop and verify downwash CFD models. The basic idea is to try to use the results of a scaled-down drone to represent that of a real-used UAV. The CFD models of both a real-used six-rotor UAV, JF01-10, and a 1:10 scaled-down small drone were developed by ANSYS. Then, the scaled-down drone was utilized to conduct trials by particle image velocimetry (PIV), so that not only distribution and speed but also flowing direction of downwash could be obtained. Results indicated the relative error between the PIV tests and the CFD models of the small UAV was less than 12%, while that between the tests and the CFD models of JF01-10 was less than 34%. It could be indicated that model migration could reflect multiple downwash characteristics but should be optimized in some complex details. This study was a preliminary but fundamental attempt to investigate CFD modelling and validation of agricultural UAVs and provided a novel thinking of downwash verification.
