HEAT RESISTANT CELLULAR STRUCTURE Russian patent published in 2015 - IPC C04B35/565 B32B18/00 B32B3/30 

FIELD: aircraft engineering.

SUBSTANCE: proposed structure comprises an encased cellular unit consisting of silicon carbide and carbon particles dispersed therein in amount of not over 14 wt %. Said cellular unit is composed of alternating interconnected flat perforated plates and corrugated impermeable webs. Note here that generatrix of crimps of every preceding impermeable web is perpendicular to that of every next web. Cellular unit is arranged in the case so that one of the sets of impermeable webs crimps generating lines are parallel with working fluid inlet direction while another set of impermeable webs is perpendicular therewith. Note here that folding bottom is blind and engaged with the case perpendicular to working fluid feed direction. Case end parallel with said direction is provided with caps with pipes to discharge used working fluid. Working fluid flow is forced through perforated plates of cellular filler structure.

EFFECT: higher operating temperature and efficiency.
