Abstract:
1. A heat shield arrangement for local separation of a flow channel within a turbine engine, with respect to a stator housing radially surrounding the flow channel, the heat shield comprising two axially opposite joining contours which are each engageable with two components which are axially adjacent along the flow channel and which each provide a complementary reception contour for the joining contours, at least one of the reception contours has an axial clearance, in which the associated joining contour is axially displaceably mounted, at least one seal being provided between the axially displaceable joining contour and the reception contour, the seal is mounted movably within the reception contour or the joining contour in such a way that the seal is deflected against a surface region of at least one of the reception contour or of the joining contour, the joining contour including a joining face in which is introduced for the seal a recess out of which the seal is deflectable so as to project partially beyond the joining face into a gap defined between the reception contour surface region and the joining face.
