Abstract
An annular air baffle for use in a cavity of an annular rotatable gas turbine engine component includes an annular split baffle ring having a plurality of circumferentially spaced apart and radially inwardly extending intermediate dams circumferentially disposed between first and second end dams. The intermediate dams and the first and second end dams extend radially inwardly from a continuous annular section. Voids are disposed between the intermediate dams and between the first and second end dams and adjacent ones of the intermediate dams. The voids are located radially inwardly of the continuous annular section and are formed by removing material from a split rolled ring rolled from barstock or a rod.
