PURPOSE: A scramjet engine is provided to prevent a flow freeze due to a sudden expansion of a combustion gas by relieving a sudden expansion angle change by forming an expanded part of a thrust nozzle unit as a round shape with inclining downwardly. CONSTITUTION: A scramjet engine comprises a center body (110). The center body comprises an influx unit (111), a combustion unit (113), a thrust nozzle unit (114), and an expanded part (115). The influx unit is arranged in a front, and formed to incline upwardly. The influx unit guides air flowed in to an air inlet port (112). The combustion unit is arranged in a center, and a supplied fuel is burnt. The thrust nozzle unit is arranged in a rear, and formed to incline downwardly. The thrust nozzle unit expands and sprays a burning gas. The expanded part induces a slow expansion of the burning gas by forming the expanded part as a round shape.
