Capture area

Definition

Capture area refers to the specific space in which an airborne wind energy system can effectively harness wind energy during its flight. This concept is critical for determining how much energy can be extracted based on the design and operational patterns of the system, influencing its overall efficiency. The capture area not only impacts the performance of the system but also plays a vital role in optimizing flight patterns for maximizing energy extraction.
