<p>Exhaust centerbody (12″) for a turbine engine, comprising a truncated downstream part (26), which is connected to an upstream part (24) by an annular ridge (22) marking a discontinuity between the outer surfaces of the upstream and downstream parts, the outer surface of the downstream part having a substantially conical general shape, of which the tip (29) is oriented downstream and is positioned in the region of the axis A, the axial half-section of this outer surface defining a line of which the upstream end part is substantially tangential to a straight line (28) passing through the above-mentioned ridge and forming a non-zero angleαwith a tangent (30) to the outer surface of the upstream part, in the region of the ridge, and of which the downstream end part is substantially tangential to a straight line (32) passing through the above-mentioned tip and forming a non-zero angleβwith the axis A.</p> |
