Abstract
A skin construction suitable for use as a high temperature airfoil surface that includes a metallic member having first and second corrugations. The first corrugations have a size and spacing which permits resilient thermal expansion of the member in a direction transverse to the direction of the first corrugations. The second corrugations are positioned in a direction that is substantially transverse to the direction of the first corrugations and the second corrugations have a size and spacing which permits resilient thermal expansion of the member in a direction generally transverse to the direction of the second corrugations. An imperforate metallic surface is integral with the metallic member. Thermal stresses imposed on the skin construction are, thus, absorbed by deformation of the first and second corrugations which act as expansion joints in permitting controlled expansion of the skin construction. In combination, a skin construction, as described, and a support structure for positioning the skin construction in spaced relation to an underlying structure. The upstanding metallic support members are connected to a surface of the metallic member of the skin construction with the support members including a corrugated upstanding surface. In combination, a high temperature skin construction and a support structure, both as described, and an underlying structure with the skin construction supported in spaced relation to the underlying structure. Insulation is placed in the space between the skin construction and the underlying structure. The combination may include means to vent the space between the skin construction and the underlying structure to ambient pressure.
