HEAT-RESISTANCE SYSTEM FOR SURFACE HEAT PROTECTION OF HYPERSONIC AIRCRAFT AND SHUTTLE SPACECRAFT Russian patent published in 2014 - IPC B64G1/58 B64C1/38 F42B15/34

Abstract RU 2509040 C2

FIELD: aircraft engineering.

SUBSTANCE: proposed system comprises composites with ceramic matrix reinforced by heat-resistant fibers and including sublimable solid substance. Said solid sublimable substance comprises stabilised pre-ceramic organosilicon polymers containing atoms C, Si and H as well as germanium heteroatoms. Heat-resistant layer as a ceramic matrix comprises carbides or borides of refractory metals or their mixes. Besides, sublimable solid substance can include refractory metal germanates.

EFFECT: efficient heat protection.
