ABSTRACT:
A flexible, low porosity airfoil skin is described which includes multilayer flexible, annealed metallic mesh members consisting of two or three such members selected from the class consisting of nickel, Monel alloy, and stainless steel, the members having a mesh size from 60 to 100, the members interlocked mechanically, and the skin having a thickness reduction in the range from 2.5 to 3.0. Such a flexible, low porosity airfoil skin is useful as a covering structure and is particularly useful as a skin or as a substrate for a cooled non-linear airfoil-shaped body, such as a turbine or compressor blade.
