ABSTRACT	Heating tests and analysis of a cooling panel that simulates the leading edge of the scramjet engine inlet or strut were performed using crossflow type water-cooled panel with a circular leading edge.The cooling panel was fabricated by nickel electroforming and heated by supersonic hot gas.An NTO/MMH rectangular chamber was used as the gas generator.The free stream Mach number at the nozzle exit was about 2.67.Water was used as the coolant and heat flux distribution was measured based on the temperature increase.Thermal analysis were performed using a two-dimension
