The device comprises an L-shaped electrode support, an annular flat copper bracket, a quartz burner, an electrode, a metal pressing piece, a water-cooling copper tube, a large high-speed aircraft round-shell structure, an annular ceramic locating rack and a round locating hole. The device can achieve a non-sectional type high-temperature thermal test for a 2-m large high-speed aircraft inner cabin structure, prevents wave-shaped peak-valley variation of a large elastomer temperature field caused by a sectional splicing heating mode, improves the temperature uniformity, reality and safe reliability of the large elastomer temperature test, and provides an important means for researching high-temperature characteristic and heat-insulation performance of the large high-speed aircraft inner cabin structure.

Description

technical field [0001] The invention relates to a non-segmented high-temperature thermal test device for the inner wall of the round shell structure of a large-scale high-speed aircraft, especially when simulating the high-temperature thermal environment inside the shell of a high-speed aircraft such as a missile, it can effectively improve the uniformity of the temperature distribution of the large-scale aircraft interior cabin structure test. It provides a good high-temperature thermal environment test method for the development of high-speed missiles and high-speed aerospace vehicles. Background technique [0002] The interior of aerospace vehicles such as missiles is equipped with an engine as a power source. The engine will generate a high temperature during ignition and flight. Due to the small space of the cabin, the temperature environment in the cabin close to the engine is very harsh, and the severe high temperature will cause Significantly reduce the strength limi...

Problems solved by technology

That is to say, it is necessary to set up many high-current wires and water-cooling channels in the high-temperature environment of the inner wall and in the limited space of the inner cavity. Not only is the test device complicated, the thermal uniformity is poor, and the complex hydropower structure in the high-temperature environment is prone to safety accidents. This makes the simulation It is much more difficult to heat the long inner wall at high temperature than the outer wall, so the research on the non-segmented overall heating technology of large projectile structures is very important
