Abstract: Results of an experimental study of the action of a nitrogen-air flow on nozzles made of various materials and sapphire at pressures in the settling chamber up to 1 GPa are presented. Formulas necessary for estimating thermal stresses in materials similar to sapphire in their properties are derived.
Keywords: heat flux power, nozzle throat, distribution of thermal strains, stresses in the nozzle body.
