摘要： The present embodiment improves the durability of an afterburner 25 and yet suppresses a reduction in the engine efficiency of an aircraft engine 1. A ring-shaped cooling channel 35 through which cooling air CA flows is formed between the outer peripheral surface of a liner 31 and the inner peripheral surface of a rear duct 29. A plurality of cooling holes 37 for blowing the cooling air CA along the inner peripheral surface of the liner 31 are formed penetrating the liner 31.
