Abstract

768,026. Wind tunnels. METROPOLITANVICKERS ELECTRICAL CO., Ltd. April 13, 1955 [April 23, 1954], No. 11831/54. Class 4. [Also in Group XXVI] In a wind tunnel the corner vanes are bounded at their ends by substantially flat and parallel end walls, the outlet ends of the vanes being additionally curved inwardly adjacent the end walls. The tendency towards the formation of vortices caused by the reduction of air velocity adjacent the end walls of the passage due to air friction is thereby counteracted. The velocity of air flow is rendered substantially uniform over the height of the passage. In the embodiment shown relating to a turbine blade, the trailing portion of the vane 2 is given greater curvature at the portions 4 and 5 adjacent the blade tip and root. The blade profiles at the tip AA, mid-section BB and root CC respectively are shown in Figs. 2, 3 and 4.
