AUGMENTOR LINER

摘要

PROBLEM TO BE SOLVED: To provide an augmentor liner being hardly affected by undesirable screech. SOLUTION: This augmentor liner includes an annulus disposed between a first wall and a second wall and a plurality of baffles. The first wall is disposed radially inside of the second wall. The plurality of baffles extend in the longitudinal direction between adjacent bands and in the height direction between the first wall and the second wall, and are circumferentially separated apart from one another by a distance. The distance between adjacent baffles is such that an acoustic wave entering an annulus compartment will travel between the first wall and the second wall in a direction having a radial component that is substantially greater than a circumferential component. The baffle spacing may alternatively be described as being such that the circumferential component of the acoustic wave is substantially damped and therefore does not materially contribute to undesirable screech.
