Abstract

A vane (30) configured to be disposed in a gas path (22, 122) defined in part by an inner surface of a case (24) of a gas turbine engine (10) is provided. The vane (30) comprises a vane body (34) configured to extend through an aperture (32) in the case (24) and a vane head (36) disposed at an end of the vane body (34). The vane head (36) has an abutting surface (46) configured to contact an outer surface (44) of the case (24) when the vane body (34) extends through the aperture (32), and a groove (38) configured to receive a sealing member (38). The groove (38) opens to the abutting surface (46) and is outwardly open relative to an inner region (49) surrounded by the groove (38). The groove (38) has an inner seating surface (50) that hinders movement of the sealing member (38) toward the abutting surface (46) and can facilitate installation of the vane (30) in the engine (10).
