HEAT-RESISTANCE SYSTEM FOR SURFACE HEAT PROTECTION OF HYPERSONIC AIRCRAFT AND SHUTTLE SPACECRAFT

摘要

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.10 cl, 5 ex
