Abstract:
1. A heat shield for mounting on a rocket engine having a thrust chamber and a nozzle expansion, said heat shield comprising: a first planar element having a front side and a back side, wherein in a mounted state of the heat shield, the first planar element extends from the rocket engine, with its front side being directly exposed to the heat radiation of at least a section of the rocket engine; and an insulating second planar element having a front side and a back side, the second planar element 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 planar element, wherein in the mounted state of the heat shield, the gap widens in an outward direction from the rocket engine, the heat shield is arranged between the thrust chamber and the nozzle expansion such that the front side of the first planar element adjoins the nozzle expansion, and the first planar element comprises a material of low emissivity with chemically inert coatings on the front and back sides such that the heat radiation absorbed by the first planar element is transported to the back side of the first planar element and emitted into the gap.
