    Abstract: A modular variable vane assembly includes an airfoil, an inner case, and an outer case. The airfoil extends between a first end and a second end along an axis. The airfoil has a connector that extends from the first end and a pivot member that extends from the second end. The inner case defines a pivot opening that is arranged to receive the pivot member. The outer case defines a first opening that extends from a first outer case surface towards a second outer case surface along the axis. The first opening is arranged to receive the connector.

    Abstract: In one exemplary embodiment, a center body support for a gas turbine engine includes a fan exit guide vane mounting ring and an outer annular wall. An aft flange extends radially outward from the outer annular wall. An inner annular wall is radially spaced from and structurally interconnected to the outer annular wall by a circumferential array of struts. A brace interconnects the aft flange to a forward portion of the outer annular wall. The aft flange includes inner and outer mounting features spaced radially apart from one another. The inner and outer mounting feature respectively receive first and second sets of fasteners. The forward portion extends in a radially outward direction from the outer annular wall. The forward portion includes a forward mounting feature that receives a third set of fasteners. The outer and forward mounting features are secured to the fan exit guide vane mounting ring respectively by the first and third sets of fasteners. Forward, outer and inner mounting features define a triangular cross-sectional shape. The forward portion has a radial inner end opposite a radial outer end. The brace is joined at the radial outer end. The brace transfers an axial load from the aft flange to the radial outer end of the forward portion.

    Abstract: An upper bifi frame for preventing air leakage in a gas turbine engine including an engine casing and a fan case is provided. The upper bifi frame includes a forward fairing having a forward fairing midsection extending between the engine casing and the fan case. The forward fairing has a forward fairing first end including a flange configured to couple to the engine casing. The forward fairing has a forward fairing second end extending from the forward fairing midsection and configured to couple to the fan case. At least one aft seal is secured to the forward fairing and forms a seal therewith. A wedge seal is coupled to the forward fairing and the at least one aft seal and is operative to prevent air leakage to a pylon that is secured to the engine casing.

    Abstract translation: 提供一种用于防止在包括发动机壳体和风扇壳体的燃气涡轮发动机中的空气泄漏的上部框架。 上部框架包括前向整流罩，其具有在发动机壳体和风扇壳体之间延伸的前向整流罩中部。 正向整流罩具有前向整流罩第一端，其包括被配置为联接到发动机壳体的凸缘。 前进整流罩有一个向前整流罩的第二端，从正向整流罩中部延伸，并配置成与风扇箱相连。 至少一个后密封件被固定到前整流罩上并与其形成密封。 楔形密封件联接到前向整流罩和至少一个后部密封件，并且可操作以防止空气泄漏到固定到发动机壳体上的吊架。
