초록

A lifting foil for an aircraft, a hydrofoil or the like having a pair of courses or wings. Vortex losses due to spanwise fluid flow are substantially reduced by joining the tips of the courses with flow guides configured for jointly terminating the undesired flows. Termination is effected by providing the flow guides with crossections cambered for reducing the dynamic pressure of fluid flowing in a spanwise direction across flow guide surfaces.

청구항

What is claimed is: 1. In a lifting foil the combination of (a) A lower course having a lower starboard margin and a lower port margin, said lower course extending sideward between said lower starboard margin and said lower port margin and being responsive to fluid flow in a direction-X, for generating a first fluid reaction force having a first lifting component in a direction-Z. (b) An upper course having an upper starboard margin and an upper port margin, said upper course being positioned above said lower course and extending sideward between said u...
