Abstract:

A stand with a magnetically compressed discharge reproduces the parameters of a shock-compressed layer (SCL) of aerospace objects moving in the atmosphere at velocities of 3–12 km/s and altitudes of 30–60 km. In a magnetically compressed discharge, the plasma with the parameters of the SCL is created not by decelerating high-velocity jets on the material under test but in the discharge along its surface and is compressed against it by an external magnetic field. The stand can be used for testing heat-shielding and structural materials, as well as for studying the radiative characteristics of an SCL, considering the ablation products of streamlined surfaces in connection with the development of optical methods for detecting and selecting objects moving in an atmosphere with hypersonic velocities.
