Abstract: A vane for an exhaust system duct in a gas turbine engine including a vane plate, a guide plate, and a baffle. The vane plate includes a leading edge, a first leg and a second leg, with the first and second legs respectively extending on opposing sides of the leading edge to form a substantially U-shaped profile. The baffle connects respective distal ends of the first and second legs. The guide plate is accommodated within the vane plate, and includes a first aperture extending along the guide plate and aligned with the leading edge. The vane further includes a fluid inlet arranged, in use, to direct a fluid flow from outside the duct into an interior of the vane.
