DEVICE FOR THERMAL PROTECTION OF HORIZONTALLY SITUATED PIPE LINE SECTIONS IN HYPERSONIC WIND TUNNELS,
Abstract
The object of the invention is a device for thermal protection of horizontally arranged pipe line sections in hypersonic wind tunnels, consisting of an internal pipe line, through which hot gas moves, and an outer pipe line - arranged concentrically. For the purpose of obtaining a uniform temperature field of the gaseous stream, minimum internal stresses in the material and deformations of the outer pipe line, the annular hollow between inner and outer pipe lines is filled in the upper part with heat insulating material, and in the lower part are situated metal screens. For the purpose of discharging the internal pipe line from pressure, its walls are uniformly perforated. (Author)
