Abstract
Thrust-chamber assembly has an expansion nozzle and a combustion-chamber wall, to which an ejector head is affixed. The part of the combustion-chamber wall adjacent to the injector head comprising a precombustion-chamber wall, in which the combustible materials delivered to the assembly first form a cooling film. There is a heat-conducting layer in at least one area of the outside of the precombustion-chamber wall and in addition, it has a covering of platinum or gold.

Thrust-chamber assembly with an expansion nozzle and a combustion-chamber wall, to which an injector head is affixed, a part of the combustion-chamber wall adjacent to the injector head comprising a precombustion-chamber wall, in which the combustible materials supplied to the assembly first form a cooling film, the assembly being characterized by a heat-conducting layer being applied in at least one area of the outside of the precombustion-chamber wall and covering at least part of an area on the outside of a cylindrical end of the injector head which is continuous with the precombustion-chamber wall.
A rocket engine thrust chamber assembly comprising:
- a precombustion chamber with a precombustion chamber wall,
- an injector head opening to the precombustion chamber and operable to inject combustible materials to the precombustion chamber,
- a main combustion chamber with a main combustion chamber wall,
- said main combustion chamber being adjacent to and downstream of the precombustion chamber,
- an expansion nozzle disposed downstream of the main combustion chamber, and
- a heat conducting layer disposed on the precombustion chamber wall at a side thereof facing away from the precombustion chamber wall,
- wherein said precombustion chamber wall includes a cylindrical section aligned with a cylindrical section of the injector head, and wherein the heat conducting layer covers at least a portion of the cylindrical section of the injector head.
A rocket powered satellite comprising a plurality of rocket engine thrust assemblies which each include:
- a precombustion chamber with a precombustion chamber wall,
- an injector head opening to the precombustion chamber and operable to inject combustible materials to the precombustion chamber,
- a main combustion chamber with a main combustion chamber wall,
- said main combustion chamber being adjacent to and downstream of the precombustion chamber,
- an expansion nozzle disposed downstream of the main combustion chamber, and
- a heat conducting layer disposed on the precombustion chamber wall at a side thereof facing away from the precombustion chamber.
