A shroud having an annular member extending along an axis from a first end to a second end. The annular member has an inside surface radially inward from an outside surface that diverges from the first end towards the second end relative to the axis. The shroud further includes a flange that extends radially outward from the outside surface and a recess, each located at the second end. The recess extends radially outward from the inside surface and circumferentially about the axis. An axial extent of the recess at least partially coincides with an axial extent of the flange.

The present disclosure generally relates to separating solid particles from an airflow in a gas turbine engine. A system for separating debris includes a first separation device in fluid communication with an inlet flow path of a compressor and a second separation device in fluid communication with an outlet flow path of the compressor and an inlet flow path of a combustor. The first separation device is adapted to remove coarse particles from the airflow. The second separation device is adapted to remove fine particles from the airflow. The course particles have a larger mean particle diameter than the fine particles.

The present invention provides compartment(s) for a turbine engine, comprising a main compartment for receiving the turbine engine and an intake compartment disposed on a side of the main compartment. The intake compartment comprises: an intake compartment body, a gas filter device and a muffler device. The gas filter device and the muffler device are disposed outside the intake port of the intake compartment. The compartment unit is configured to have a first gas path which permits air for combustion in the turbine engine to pass from the external through the gas filter device and the first muffler device in turn into the intake compartment body, and then be delivered through the exhaust port of the intake compartment to the turbine engine in the main compartment. According to the present invention, both the intake compartment and the main compartment may be provided with a filter device and muffler device(s) to meet requirements for the intake air amount and cleanness of the turbine engine and the temperature in the main compartment and meanwhile reduce the intake noise.
