Abstract: A Coanda vehicle comprises a canopy (1) having an upper convex surface (7), an impeller (2, 5), means (1, 3)defining a path for fluid which passes through the impeller and curves from a relatively axial direction to a relatively radial direction, the path terminating at a position adjacent the said surface so that fluid flow over the surface produces lift. The invention proposes the use of a deflector (8) located in the said path so that fluid flows over opposite surfaces of the deflector, the deflector being curved in the same direction as the curvature of the path. By employing the invention it becomes possible to change the velocity profile across the fluid path, this offering a potential for improved performance.

Abstract: In craft of the type in which a fan (2) is used to direct a radial jet of air over a curved canopy (1), the canopy is shaped so as to divert the flow of air from a radial to an axial direction to produce lift. The air flowing from the fan tends to follow, depending on its velocity, a complex swirling trajectory over the canopy surface rather than a direct path and the present invention arose from a proposition that the swirling action might have an adverse effect on lift. The invention proposes the use of an aerofoil control surface (6) upstream of the lift producing surface (1) and angled away from a radial direction towards or inline with or beyond the direction of flow of fluid emanating from the impeller. By employing the invention fluid flow is redirected from a direction having a circumferential component towards a radial direction before reaching the lift producing surface. In this way it is found to be possible to improve lift and also to prevent counter spin.
