Description

Technical field [0001] The invention relates to the technical field of satellite transmitter thermal protection, in particular to a ground verification system for verifying the temperature resistance and heat insulation performance of a satellite engine thermal protection component. Background technique [0002] With the development of the aerospace industry, the radius of human exploration has increased, and the orbital height of satellites has become higher and higher. From sun synchronization and geosynchronization to the moon and Mars, the weight requirements of satellites are becoming more and more stringent. On the other hand, the cruising section and orbit maintenance of high-orbit satellites and deep-space exploration satellites need to increase the number of engines, while the solid wall radiation and plume temperatures are as high as 1000°C when the engines are working, and the products and components on the satellite need to be heated. Protection, the increase in the n...

Problems solved by technology

On the other hand, the cruising segment and orbit maintenance of high-orbit satellites and deep-space exploration satellites need to increase the number of engines, and when the engines are working, the solid-wall radiation and plume temperatures are as high as 1000 ° C, and the products and components on the planet need to be heated. protection, the increase in the number of engines allowed a significant increase in the weight of thermal protection

[0003] In order to reduce the weight of the thermal protection of the engine, the structure of the thermal protection has to be optimized. Whether the optimized thermal protection components can meet the thermal protection requirements of satellite products and components, simulation alone is not enough to eliminate the huge damage caused by thermal protection failure to the satellite. Safety risk, high-altitude thermal test run with real engine is very expensive
