Abstract
Successful test production of transverse and longitudinal automatic feed system in burnt corrosion test electric arc heater burn corrosion testing is the principal means for ground simulation tests in research on the heat shield layers of reentry vehicles. In order to better simulate flight conditions, people have consistently put effort into improving the capabilities of electric arc heaters. In line with this improving of the operating technology of electric arc heaters, use was made of various types of water cooled sensor electrodes, which are easily destroyed by burning. Because of this, instantaneous state enthalpy or heat content probes, zero point heat measuring devices, and other similar rapid scan type probes should be operated in order to survive. Moreover, the latter require a set of adjustable velocity high speed horizontal movement structures. Only then is operation possible. Increases in the amount of burn corrosion make it easy for models to get out of areas of equal pressure. It is necessary to automatically compensate for the amount of burn corrosion retreat. (eg)
