Abstract : The cylindrical sections of a gas turbine engine are provided with flanges at each end for bolting the sections to one another. Each flange includes a series of strengthening ribs of arcuate configuration extending axially outward from the center of the wall thereof between the several bolts needed to join the adjacent sections together. The ribs serve to eliminate the need for at least 2 out of 3 bolts while effectively maintaining the required stiffness and sealing capability. (Author)
