    • A gas turbine engine component assembly comprises a first component (62a 1 ) and a second component (62a 2 ) circumferentially spaced from the first component (62a 1 ) relative to an engine center axis (A). A first baffle (72) is associated with the first component (62a 1 ). A second baffle (72) is associated with the second component (62a 2 ). Each of the first and second baffles (72) includes at least one radial baffle tab (206). A gap (212) is between the first and second baffles (72) to define a cooling air inlet. A first coverplate (200) is associated with the first baffle (72) to cover a first portion of the gap (212). A second coverplate (200) is associated with the second baffle (72) to cover a second portion of the gap (212). The first and second coverplates (200) are separate from each other, and include at least one coverplate radial tab (204) that cooperates with an associated at least one baffle radial tab (206) to prevent leakage gaps between the first and second baffle plates (72) and the first and second coverplates (200).
    • 燃气涡轮发动机部件组件包括相对于发动机中心轴线(A)与第一部件(62a 1)周向间隔开的第一部件(62a 1)和第二部件(62a 2)。 第一挡板(72)与第一部件(62a 1)相关联。 第二挡板(72)与第二部件(62a 2)相关联。 第一和第二挡板(72)中的每一个包括至少一个径向挡板(206)。 间隙(212)位于第一和第二挡板(72)之间,以限定冷却空气入口。 第一盖板(200)与第一挡板(72)相关联以覆盖间隙(212)的第一部分。 第二盖板(200)与第二挡板(72)相关联以覆盖间隙(212)的第二部分。 第一和第二盖板(200)彼此分离,并且包括与相关联的至少一个挡板径向突片(206)配合的至少一个盖板径向突片(204),以防止第一和第二挡板之间的泄漏间隙 (72)和第一和第二盖板(200)。
