Orientation

Definition

Orientation refers to the position or alignment of an object in relation to a reference point or direction. In the context of aerodynamics, particularly for kites, orientation is crucial as it affects how airflow interacts with the kite's surface, influencing lift and drag forces. Understanding the optimal orientation helps in maximizing performance and efficiency during flight.
