Film- und Prallkühlung für Platten

摘要

A cooling system for reducing the temperature of an exhaust-impinged structural panel includes an upper, primary cooling panel having boundary layer film-forming openings therein, a middle, secondary cooling panel having openings for directing a flow of cooling fluid into impingement with the primary cooling panel, and a lower cooling panel. The lower and upper panels together delimit a truss structure which structurally reinforces the cooling system, and the lower panel forms with the upper panel channels for conducting pressurized fluid first to the openings of the secondary cooling panel and then to the openings of the primary cooling panel. A method is also disclosed and claimed for fabricating the upper and lower cooling panels unitarily with the middle cooling panel. <IMAGE>
