Abstract
【解決手段】本システムは、燃焼缶120のヘッドエンド領域に隣接して据付けられた少なくとも1つの共振器150を含むことができる。少なくとも1つの共振器150は、低温側面孔パターン(156)を形成した複数の孔を有する第1の側面(152)と、高温側面孔パターン(164)を形成した複数の孔を有する第2の側面(160)と、低温側面及び高温側面によって実質的に形成された空洞(158)とを含むことができる。低温側面孔パターン(156)は、該低温側面孔パターン(156)内の複数の孔の各々が第2の側面表面(162)に実質的に衝突する冷却空気の噴流を可能にするように配向することができ、また高温側面孔パターン(164)は、該高温側面孔パターン(164)内の複数の孔の各々が第1の側面表面(154)に実質的に衝突する作動流体の噴流を可能にするように配向することができる。
