Abstract: A heat shield for mounting on a heat-radiating object, particularly on a rocket engine comprises a first planar element having a front side and a back side. In its mounted state, the first planar element extending from the heat-radiating object toward the outside, with its front side being exposed to the heat radiation at least of a section of the heat-radiating object. A second insulating element having a front side and a back side is arranged on the back side of the first planar element in such a manner that a gap is formed between the back side of the first planar element and the front side of the second element. In the mounted state of the heat shield, the gap widens in the direction from the heat-radiating object toward the outside.
