APPARATUS FOR PROTECTION OF ROTOR VANES AGAINST SURFACE EROSION CAUSED BY IMPINGEMENT OF HIGH SPEED LIQUID DROPS

摘要

The surface of a structural part such as for example the leading edge portion of a turbine vane or airplane wing is protected against erosion which would otherwise be caused by impingement of high speed liquid drops thereon by positioning an array of flexible baffles in front of the surface. These baffles which are slightly spaced from the surface of the vane or wing serve to intercept the liquid drops resulting in a division thereof into smaller drops which are simultaneously decelerated as a result of flexation of the baffles.
