Depowering mechanisms

Definition

Depowering mechanisms are systems or strategies used to reduce the power output of airborne wind energy systems, particularly kites, to ensure safe operation and maintain optimal performance in varying wind conditions. These mechanisms are crucial for managing the aerodynamic forces acting on the kite, allowing it to adapt to changing flight dynamics without compromising safety or efficiency. By regulating power output, these mechanisms help prevent structural failures and enhance overall system reliability.
