Abstract
An apparatus for removing heat from a thermally highly loaded structure, such as a spacecraft or hypersonic aircraft, is based on an endothermic reaction, and particularly the water gas synthesis reaction. A system of pipes (2) is arranged in the areas of the structure that are to be cooled. The pipes (2) are filled with a carbon core that includes passages through which steam passes, to react with the carbon and generate water gas. The system preferably includes a steam generator that uses some of the heat from the areas to be cooled for generating the steam that is conveyed through the carbon filled pipes (2).
Claims18
An apparatus for removing heat from a thermally loaded structure having a heated portion, said apparatus comprising a pipe that is arranged at said heated portion and that has a water steam, inlet into an interior of said pipe, a water steam generator connected to said water steam inlet of said pipe, and a reducing agent provided in said interior of said pipe such that said reducing agent will be in direct contact with water steam-introduced into said interior of said pipe from said steam generator, and such that an endothermic chemical reaction will take place between said water steam and said reducing agent using said heat removed from said thermally loaded structure.
In a flying body having a fuselage skin surface subject to aerodynamic frictional heating as said flying body passes through earth's atmosphere, an improved cooling system comprising first means for generating water steam, second means connected to said first means for conveying water steam from said first means and for heating said water steam with heat from said fuselage skin surface, and reducing agent means cooperating with said second means for reducing said heated water steam in an endothermic chemical reduction reaction.
