Abstract: A fluid flow assembly may include an orifice plate having a set of orifices and a plenum defined by a blade outer air seal. The set of orifices may be aligned with and in fluid communication with the plenum. A gas turbine engine may include a vane outer support having an orifice plate, wherein the orifice plate includes a plurality of sets of orifices. The gas turbine engine may also include a blade outer air seal defining a plurality of plenums. Each set of orifices of the plurality of sets of orifices may be forward relative to and substantially axially aligned with a respective plenum of the plurality of plenums.

Abstract: A seal runner may have an inner annular member, an outer annular member, and a radial wall member joined to the inner annular member according to an angle and extending from the inner annular member to the outer annular member. The seal runner may be positioned axially along a shaft and a bearing may be positioned axially along the shaft such that it is radially between the inner annular member and the outer annular member. In this regard, the seal runner may resemble a “C-shape.” A seal may interface with a seal land radially outboard of the outer annular member. Thus, the seal may be positioned axially near to the bearing so that the axial length of a shaft and accompanying bearing compartment hardware may be minimized.
Abstract translation: 密封流道可以具有内环形构件，外环形构件和径向壁构件，所述径向壁构件根据角度并且从内环形构件延伸到外环形构件而连接到内环形构件。 密封流道可以沿轴轴向定位，并且轴承可以沿着轴轴向定位，使得其在径向地位于内环形构件和外环形构件之间。 在这方面，密封流道可以类似于“C形”。密封件可以与外部环形构件的径向外侧的密封件接合。 因此，密封件可以轴向定位在轴承附近，使得轴的轴向长度和伴随的轴承隔室硬件可以被最小化。

Abstract: A blade outer air seal assembly includes a support structure. A blade outer air seal has a plurality of segments that extends circumferentially about an axis and is mounted in the support structure. At least two of the segments have a base portion that extends from a first circumferential side to a second circumferential side. A first protrusion extends from the first circumferential side and has a first radially extending slot. A second protrusion extends from a second circumferential side and has a second radially extending slot. A feather seal is arranged in the first radially extending slot and the second radially extending slot between at least two segments.
