APPARATUS FOR DETERMINING OXIDATION RESISTANCE OF CARBON-CARBON COMPOSITE MATERIAL Russian patent published in 2014 - IPC F02K9/96 G01M15/14 

FIELD: chemistry.

SUBSTANCE: invention can be used in making components from carbon-carbon composite material operating in a high-temperature oxidative environment on the surface of rocket equipment. The apparatus for determining oxidation resistance of a carbon-carbon composite material, including with a protective coating, which includes a chamber made of refractory material for holding a sample of test material and a nozzle for feeding a gas stream into the chamber on the front wall of the apparatus, is provided with a set of detachable front walls of different thickness, wherein the nozzle is located at different angles to the longitudinal axis of the chamber of the apparatus, wherein the chamber of the apparatus is placed in a metal housing with a heat-protective cover, the heat-protective cover and the chamber being detachable.

EFFECT: invention enables simulation of the effect of a high-temperature gas stream on a component of rocket equipment in conditions close to real conditions, and determination of oxidation resistance of a carbon-carbon composite material with action of a high-temperature gas stream at different angles and at different distances.
