    Abstract: A method for assembling an airfoil includes pressing a blade body together with at least one of a blade sheath and a blade cover between a plunger and a die base to join the blade body to the blade sheath and/or the blade cover. The method can include transferring heat from the plunger and/or the die base to at least one of the blade body, the blade sheath and the blade cover to cure an adhesive.

    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。
