Bridges

Definition

In the context of aerodynamics, bridges refer to structural elements that connect different parts of a vehicle or structure, ensuring stability and facilitating the flow of air over surfaces. These components play a crucial role in the overall aerodynamic performance, influencing how air interacts with the structure and contributing to stability and control during flight. Understanding bridges is essential for analyzing the effects of aerodynamic forces on structures like wings or fuselages.
