Abstract: An approach is developed for estimating the availability of materials for fabrication of nozzles to be used in aerodynamic facilities with extremely high pressures, where commercial nitrogen and air are used as test gases. Some promising materials are analyzed.

Keywords: stresses in the nozzle insert, thermal endurance of the material.
