👉 Roudas, in aeronautics, are circular trajectories of an aircraft or other aerodynamic system. They represent the path taken by an object as it moves through the air, and they help to determine its stability and maneuverability. These trajectories can be defined based on various factors such as the shape of the body, the size of the wings, the propellers, and the aerodynamics of the aircraft. Roudas are essential components in the design of aircraft for safety, performance,
