Abstract (en)
A turbine engine (10) comprises a compressor section (12), a combustion section (14) and a turbine section (16) in serial flow arrangement, with the combustion section (14) having a combustor (30) defining a longitudinal axis (LA). The combustor (30) comprises a combustor liner (94) at least partially defining a combustion chamber (98), a fuel passage (122) fluidly coupled to the combustion chamber (98), a compressed air passage (110) fluidly coupling the compressor section (12) to the combustion chamber (98), a dome plate (142) separating the combustion chamber (98) from the compressed air passage (110) and having a set of apertures (146, 246, 346) fluidly coupled to the compressed air passage (110), and a set of resonator cavities (150, 250, 250a, 250b, 350, 350a-f) proximate the dome plate (142) and fluidly coupled to the set of apertures (146, 246, 346).
