Abstract:
1. A method of fabricating an exhaust duct and mixer assembly for use with a gas turbine engine, comprising: providing an annular shroud; forming a plurality of air foils, each having a front end, a rear end, an inner side and an outer side; forming a plurality of insert members, each having a front edge, a rear edge, and first and second side edges defining a surface; mounting the air foils to the shroud on a surface thereof in a circumferentially, substantially equally spaced-apart relationship; securing one of the insert members to at least two adjacent air foils, thereby in combination with the adjacent air foils forming a first flow path along one side of the insert member for directing exhaust gases rearwardly and a second flow path along another side of the insert member for directing a bypass air flow rearwardly when the assembly is installed on the engine; and repeating the step of securing insert members until the assembly is completed.
