METHOD FOR MAKING FILM COOLED SHEET METAL PANEL

Abstract

A method for fabricating a brazed sheet metal panel for use in an engine nozzle structure is described which comprises steps of providing a first sheet metal member having a plurality of spaced dimples formed therein and a second sheet metal member having a plurality of spaced cutouts corresponding in position to the spaced dimples in the first member, providing a mixture of powdered braze material and polymer binder and spraying a layer of the mixture onto a surface of the second member, assembling the first and second members in laminar contact with the cutouts of the second member in registration with the dimples of the first member and the layer of mixture between the members, and then heating the assembly under vacuum to a temperature sufficient to fuze the braze powder and to volatilize the binder.
