Abstract:
A component of a gas turbine engine, the component having: an internal cooling cavity extending through an interior of the component; a baffle insert (32) configured to be inserted into the internal cooling cavity; a plurality of trip strips (40) extending upwardly from an exterior surface of the baffle insert; and at least one rib extending upwardly from the exterior surface (38) of the baffle insert, wherein the plurality of trip strips and the at least one rib (42) are spaced from an interior surface of the internal cooling cavity.
Abstract:
An airfoil (200) is provided. The airfoil (200) may comprise a cross over (232), an impingement chamber (230) in fluid communication with the cross over (232), and a first trip strip (236; 260...270) disposed on a first surface (237) of the impingement chamber (230). A cooling system is also provided. The cooling system may comprise an impingement chamber (230), a first trip strip (236; 260...270) on a first surface (237) of the impingement chamber (230), and a second trip strip (238; 280...290) on a second surface (239) of the impingement chamber (230). An internally cooled engine part is further provided. The internally cooled part may comprise a cross over (232) and an impingement chamber (230) in fluid communication with the cross over (232). The cross over (232) may be configured to direct air towards a first surface (237) of the impingement chamber (230). A first trip strip (236; 260...270) may be disposed on the first surface (237) of the impingement chamber (230).
