There have been past proposals for air vehicles employing the Coanda effect. In these proposals, a jet of fluid, usually air, is made to flow radially outwardly over 5 a dome-shaped canopy to create lift. A cross-section through the canopy is curved to follow a segment of a circle or it may have a radius of curvature that increases in the direction of flow. In the invention, the radius (r) of the canopy curve decreases towards the downstream direction (x) in a way that is related to the decrease in the width of 10 the jet as it flows over the surface. Th...


The invention claimed is: 1. A vertical take-off aircraft, comprising: means for causing fluid to flow radially outwardly from a central position over a canopy having a surface with double convex curvature about an axis, this surface serving to divert the radial flow towards an axial direction by operation of the Coanda effect and having a radius of curvature which decreases progressively less rapidly with increasing distance from the axis to a point close to but separated from a peripheral edge of the canopy; and a peripheral portion extending from the...
