초록 ▼

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.

대표청구항 ▼

A device to reduce the drag experienced by bodies in motion within and relative to masses of fluid, comprising: a body intended for motion within and relative to a mass of fluid and presenting a body surface; a member of cambered aerofoil cross-section having a given length mounted upon said surface so that the span of said member projects outward from said surface into the space where a local stream of fluid will form in use, whereby in Such use said member will tend to divert said local stream back into the free stream and in so doing experience useful thrust; in which said camber of said cross-section of said member varies to allow for change in the direction of said local stream, the variation in said camber occurring over the length of said member from a high degree of camber in one sense near said surface, said degree of camber first falling to zero along said length and then increasing in the opposite sense near the tip end of said span of said member.
