<p>An acoustic dampener (300) for a gas turbine engine comprises a first wall (302), an orifice plate (304), and second wall (306). The first wall (302), the inner liner of the combustion chamber, e.g., separates a first fluid source, combustion gases, from a second fluid source, combustion air. The first wall (302) has several holes (312) for allowing fluid communication between the first fluid source and a first cavity (308) of the acoustic dampener (300). The orifice plate (304) separates the first cavity (308) from a second cavity (310) of the acoustic dampener (300). The orifice plate (304) has several holes (314) for allowing fluid communication between the first cavity (308) and the second cavity (310). A second wall (306) separates the second cavity (310) from the second fluid source. Optionally, the second wall (306) has several holes for allowing fluid communication between the second cavity (310) and the second fluid source.</p> |
