Wake capture refers to a process or technique used in various fields, particularly in the study of fluid dynamics, engineering, and aviation. It is the act of deliberately harnessing or utilizing the energy or momentum created by the wake of a moving object, such as a vehicle or aircraft, for a specific purpose.
In fluid dynamics, wake capture involves taking advantage of the vortices, or swirling patterns of fluid flow, that are created behind a moving object. By positioning a secondary object in the path of the wake, the captured energy can be used to generate power, enhance propulsion, or improve maneuverability. This principle has applications in the design of renewable energy systems, marine propulsion, and aerospace engineering.
In aviation, wake capture refers to techniques used by pilots to safely fly in the wake turbulence generated by larger aircraft. By flying within the wake vortex of a preceding aircraft, a smaller aircraft can benefit from the reduced air resistance to improve fuel efficiency or gain altitude. However, wake capture must be done with caution, as the powerful vortices created by large aircraft can pose a risk to smaller planes if not managed properly.
Overall, wake capture involves strategically utilizing the energy or vortices generated by the wake of a moving object for various applications, ranging from improving vehicle efficiency to enhancing flight performance.
