    • A gas turbine engine includes a combustion section 26 spaced between a compressor section in a turbine section. The combustion section 26 defines a combustion chamber 88 and includes a combustor member defining an opening 118 to the combustion chamber 88. A mounting assembly 120 extends around or is positioned adjacent to the opening 118 defined by the combustor member. An igniter 114 extends through a ferrule 122 of the mounting assembly 120 and includes a distal end 116 positioned proximate the opening 118 in the combustor member. The igniter 114 defines a plurality of channels 138, each channel 138 extending between a first end 140 and a second end 142. The first end 140 is positioned away from the distal end 116 of the igniter 114 relative to the second end 142, and the second end 142 is a terminal end spaced from the distal end 116 of the igniter 114.

    • An active noise suppression apparatus and method for reducing jet engine noise and buffeting. A plurality of resonant cavities (12) are formed in a structural member disposed on or adjacent to a jet engine exhaust nozzle (22). Each resonant cavity opens toward an output slot. A compressed air chamber is used to supply a pressurized, supersonic jetstream airflow through the inlet port (16) into the interior area of the resonant cavity (12). This causes a high frequency, pulsed, excitation airstream to be generated outwardly form the cavity, out of the output slot and into the developing shear layer of the exhaust airflow. This high frequency, pulsed, excitation airstream induces modifications in the shear layer, which leads to a major reduction in the noise and buffeting generated by the developing shear layer.
    • 一种用于减少喷气发动机噪声和缓冲的主动噪声抑制装置和方法。 多个谐振腔(12)形成在布置在喷气发动机排气喷嘴(22)上或与其相邻的结构件中。 每个谐振腔朝向输出槽打开。 压缩空气室用于将加压的超音速喷射流气流通过入口(16)供应到谐振腔(12)的内部区域中。 这导致高频脉冲激发气流从空腔向外产生出输出槽并进入排气气流的显影剪切层。 这种高频,脉冲的激发气流在剪切层中引起修改,这导致显影剪切层产生的噪声和缓冲的显着降低。
