Abstract
A bleed valve system for a gas turbine engine that includes a retaining ring and a metering ring. The retaining ring abuts an end of a bleed air duct and defines a plurality of retaining ring apertures. The metering ring that is at least partially disposed within the bleed air duct and abuts the retaining ring, the metering ring defining a plurality of metering ring apertures, the metering ring being rotatable relative to the retaining ring to selectively facilitate a fluid flow through the bleed air duct.

A bleed valve system for a gas turbine engine, comprising:
- a retaining ring that abuts an end of a bleed air duct, the retaining ring defining a plurality of retaining ring apertures;
- and
- a metering ring that is at least partially disposed within the bleed air duct and abuts the retaining ring, the metering ring defining a plurality of metering ring apertures, the metering ring being rotatable relative to the retaining ring to selectively facilitate a fluid flow through the bleed air duct.
A gas turbine engine, comprising:
- a case surrounding a main body that is disposed about a central longitudinal axis, the main body having a first wall that extends between a first wall first end and a first wall second end, a second wall that extends between a second wall first end and a second wall second end, and an intermediate wall disposed between the first wall and the second wall and extends between an intermediate wall first end and an intermediate wall second end;
- and
- a bleed valve system, comprising:
- a retaining ring that is disposed between the first wall and the intermediate wall, the retaining ring having a first portion that defines a plurality of retaining ring apertures and a second portion that extends from the first portion towards the intermediate wall second end, and
- a metering ring that abuts the first portion, the metering ring defining a plurality of metering ring apertures.
