Abstract : The presented final report contains the summary of the results of three previous stages of serviceability investigation of strut fuel feed system intended to inject fuel into supersonic high-enthalpy flow of two-dimensional small-scale model scramjet combustor. The results of the fourth stage of the work on EOARD Order No F6170896W0221 are presented in section concerning fuel strut thermal state in free supersonic flow investigation. This strut is designed, manufactured and tested in accordance with modeling concept and studies methodology taking into account results of the first three stages. The strut is intended for the following bench investigations of combustion and heat exchange problems in duct of combustor burning hydrocarbon fuels of various types, injected chiefly in gaseous phase. This strut dimensions differ from dimensions of earlier tested struts. They correspond to the scale of scramjet module for flying test beds of the second generation of 'IGLA' type. The final section of the report incorporates the results generalization of model studies of combustor operating process and fuel struts cooling system and the recommendations on these results use in the cases that combustor of different sizes burning different types of fuels operates.
