    • 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.
    • 用于环形可旋转燃气涡轮发动机部件的空腔中的环形空气挡板包括环形裂缝挡板环,其具有多个周向间隔开且径向向内延伸的中间水坝,其周向设置在第一和第二端部坝之间。 中间坝和第一和第二端坝从连续的环形区段径向向内延伸。 空隙被布置在中间水坝之间以及在第一和第二端坝和相邻的中间水坝之间。 空隙位于连续环形部分的径向内侧,并且通过从从棒料或棒轧制的分割轧制环去除材料而形成。
