A component for the turbine of a gas turbine engine is provided. The component two facing walls interconnected by one or more generally elongate divider members to partially define side-by-side, generally elongate, cooling fluid passage portions which form a multi-pass cooling passage within the component. The passage portions are connected in series fluid flow relationship by respective bends formed by joined ends of neighbouring of the passage portions. The component further includes one or more core tie linking passages formed in the divider members. The or each core tie linking passage has an entrance at an upstream passage portion and an exit at a neighbouring downstream passage portion, and allows cooling fluid to leak therethrough to bypass the bend formed by the joined ends of the neighbouring passage portions. One or more differential pressure reducing arrangements are formed in the multi-pass cooling passage adjacent respective of the core tie linking passages. The or each arrangement reduces the difference in the static pressure of the cooling fluid between the entrance of the respective core tie linking passage and the exit of that core tie linking passage. |
