Analisis Aerodinamika Pada Pesawat Nirawak MEGANTARA Menggunakan Metode CFD

Abstract

The fundamental mechanics of a moving body through a fluid dictates that a body will experience a force acting opposite as a result of friction with the fluid molecules being moved away by the body. This phenomenon can be very complex and unpredictable when it is observed in an experimental setting. By using numerical solutions with the available advancements in fluid simulation software, The flow of the fluid over a body can be observed in a much better light through CFD simulation. In this research, the aerodynamic characteristics of the unmanned aircraft “MEGANTARA” will be simulated using ANSYS Fluent 2023 R2. With the speed variatons of 22,2 m/s; 27,7 m/s; 33,3 m/s; 38,8 m/s; 44,4 m/s; and 55,5 m/s which represents the take off, cruise, and maximum speed. the results will include the coeffitient of lift, drag, and the visualisation of fluid flow through the object, which will hopefully bring a better understanding of the air flow and can become a valuable input for future competitions.
