Acoustic isolation of the stator of a low pressure compressor

摘要

The low-pressure compressor stator, having a separator nose (16) at its forward end for primary and secondary flows, and acoustic panels (20) extending rearwards from it, has a shoulder (22) on the nose to receive the forward edge of each panel. The shoulder is located adjacent to the cylindrical assembly surface (24) on which the acoustic panels are bolted, the panels having inserts (39) to receive the bolts threaded shanks.
