Abstract
An upper bifurcation (bifi) frame (100) for providing an aerodynamic fairing around a pylon and for preventing air leakage in a gas turbine engine (20) including an engine casing (112) and a fan case (160) is provided. The upper bifi frame includes a forward fairing (110) having a forward fairing midsection (111) extending between the engine casing and the fan case. The forward fairing has a forward fairing first end (114) including a flange (113) configured to couple to the engine casing. The forward fairing has a forward fairing second end (116) extending from the forward fairing midsection and configured to couple to the fan case. At least one aft seal (118) is secured to the forward fairing and forms a seal therewith. A wedge seal (140) 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.
