A fairing system for a rotorcraft, comprising: a hub fairing (102, 104) arranged and rotatable about a rotation axis; a shaft fairing arranged about the rotation axis and adjacent to the hub fairing (102, 104), which shaft fairing is fixed or movable about the rotation axis and is movable relative to the hub fairing (102, 104); and a seal assembly (108, 110) interposed axially between the hub fairing (102, 104) and the shaft fairing, wherein the seal assembly (108, 110) spans a gap (G1, G2) defined between the hub fairing (102, 104) and the shaft fairing, wherein the hub fairing and the shaft fairing are both removably mounted to the seal assembly (108, 110) such that either or both the hub fairing (102, 104) and the shaft fairing can be dismounted from the seal assembly (108, 110) without disturbing the seal assembly (108, 110), and characterized in that: the seal assembly further includes a seal race (130, 140) with sealing face (130A, 140A) and channel (130C, 140C), in that a portion of the hub fairing (102, 104) is seated within the channel (130C, 140C) or a portion of the shaft fairing is seated within the channel (130C, 140C), and in that the channel has a channel profile which includes axially opposed faces, and in that the portion of the hub fairing (102, 104) or shaft fairing seated in the channel (130C, 140C) is in contact with one of the axially opposed faces, or the seal race (130, 140) is configured to axially fix the hub fairing (102, 104) relative to the seal race (130, 140). a hub fairing (102, 104) arranged and rotatable about a rotation axis; a shaft fairing arranged about the rotation axis and adjacent to the hub fairing (102, 104), which shaft fairing is fixed or movable about the rotation axis and is movable relative to the hub fairing (102, 104); and a seal assembly (108, 110) interposed axially between the hub fairing (102, 104) and the shaft fairing, wherein the seal assembly (108, 110) spans a gap (G1, G2) defined between the hub fairing (102, 104) and the shaft fairing, wherein the hub fairing and the shaft fairing are both removably mounted to the seal assembly (108, 110) such that either or both the hub fairing (102, 104) and the shaft fairing can be dismounted from the seal assembly (108, 110) without disturbing the seal assembly (108, 110), and characterized in that: the seal assembly further includes a seal race (130, 140) with sealing face (130A, 140A) and channel (130C, 140C), in that a portion of the hub fairing (102, 104) is seated within the channel (130C, 140C) or a portion of the shaft fairing is seated within the channel (130C, 140C), and in that the channel has a channel profile which includes axially opposed faces, and the seal assembly further includes a seal race (130, 140) with sealing face (130A, 140A) and channel (130C, 140C), in that a portion of the hub fairing (102, 104) is seated within the channel (130C, 140C) or a portion of the shaft fairing is seated within the channel (130C, 140C), and in that the channel has a channel profile which includes axially opposed faces, and in that the portion of the hub fairing (102, 104) or shaft fairing seated in the channel (130C, 140C) is in contact with one of the axially opposed faces, or the seal race (130, 140) is configured to axially fix the hub fairing (102, 104) relative to the seal race (130, 140).
