Abstract

See full text

A tail pipe (50) comprises: a pipe (51); an acoustic attenuator (61) that forms an acoustic space (Ss) on the outer peripheral side of the pipe (51); and a cooling air jacket (65) that forms a cooling air space (Sa) isolated from the outer space (So), which is the space on the outer peripheral side of the pipe (51). The pipe (51) has: a first air flow path (56) that is formed between the outer peripheral surface (55o) and the inner peripheral surface (55i); and an acoustic hole (59) that penetrates from the acoustic space (Ss) to a combustion space (Sc), which is a space on the inner peripheral side of the pipe (51c). The first air flow path (56) has: an inlet (56i) that faces into the cooling air space (Sa) and guides the air in the cooling air space (Sa) into the first air flow path (56); and an outlet (56o) that faces into the acoustic space (Ss) and guides the air passing through the first air flow path (56) into the acoustic space (Ss).
