ABSTRACT:
Devices to reduce the drag experienced by aircraft and other travelling bodies, comprising sail-like members mounted on the body surface. These members project into the local stream that forms close to the surface during motion, and tend to divert that local stream back into the free stream direction and in so doing to experience useful thrust. The members are cambered and the camber varies from root to tip to allow for change in the local stream direction as distance from the surface increases. Special sails for use on surfaces subject to some complex flows, adjustable sails and arrays of several sails for use especially at aircraft wing tips, are also proposed.
