SOME FEATURES OF COATINGS FOR TILES REUSABLE HEAT-PROTECTION ORBITING SPACECRAFT

The surfaces of orbiting spacecraft type «Buran», «Space Shuttle» protected special insulating materials. However, these insulating materials have demanded protection from erosion and moisture. This article presents the results of many years of work to create, research and testing of high-temperature reactive-cured coatings for heat-protection spacecraft «Buran».

THE THERMAL DIFFUSIVITY OF THE GRADIENTTHERMAL INSULATION MATERIAL

The features of the temperature front passing through a series of single-layer and multi-layer insulation materials with different densities. Presented schedules temperature front through the bulk fibrous material in unilateral heating at 1200 and 1590°C. The effect of the order of layers of different density on the effectiveness of insulation. A qualitative assessment of the effectiveness of thermal insulation material in a one-sided heating.

THE METHODS OF DETERMINATION OF Al2O3 SINGLE-CRYSTAL FIBERS CROSS-SECTION AREA FOR TENSILE STRENGTH CALCULATION

Three methods of determnation of single-crystal fibers cross-section area are pre-sented in this paper, the optimum variants are chosen and the results of fiber strength calculation after room and high-temperature tensile tests are set out. The inaccuracy caused by temperature expansion of the material is estimated.

COATINGS FOR PROTECTION OF HYDRAULIC UNITS

It has been established that an optimum variant of coatings resistant to liquids for hydraulic systems NFL-4 and NFL-5u compositions are based on branched epoxy oli-gomers, curing compounds on the basis of silicone amines. New coatings have good physical and mechanical properties, good adhesion and resistance to liquids NFL-4 and NFL-5u. Compared with the previously applicable systems paint-and-lacquer coatings (PLC) use of the new systems reduces the toxicity and excludes the use of materials con-taining foreign scarce raw material components.
