ABSTRACT:
A gas turbine engine has an axial flow compressor, the inner wall of which is provided with a lining adapted to capture and retain any small hard foreign objects impinging upon it. The lining consists of an aluminum alloy sheet having a silicone rubber coating bonded to one side and a stainless steel honeycomb structure bonded to the other side. The honeycomb structure is bonded in turn to the inner wall of the compressor casing. The silicone rubber coating has a plurality of finely divided hollow silica microspheres dispersed within it.
