Bleed valve resonator drain
A bleed valve includes a valve body which includes an aperture. A resonator is in fluid communication with the aperture in the valve body. A drain valve is in fluid communication with the resonator.
1. A gas turbine engine comprising:
a compressor section;
a bleed duct in communication with the compressor section; and
a bleed valve in communication with the bleed duct comprising:
an aperture in a valve body;
a resonator in fluid communication with the aperture; and
a drain valve in fluid communication with the resonator, wherein the drain valve includes a body portion at least partially surrounding a slider.
2. The gas turbine engine of claim 1 , wherein the bleed valve is a 2.5 bleed valve for the gas turbine engine.
3. The gas turbine engine of claim 1 , wherein the bleed valve is located adjacent an aft stage of a low pressure compressor of the compressor section.
4. The gas turbine engine of claim 1 , wherein the slider is configured to move in an axial direction relative to an axis of the body portion.
5. The gas turbine engine of claim 4 , further comprising a spring for biasing the slider relative to the body portion.
6. The gas turbine engine of claim 1 , wherein the slider includes an engagement portion for engaging a static structure on the gas turbine engine.
7. The gas turbine engine of claim 1 , wherein the slider includes a seal portion including at least one O-ring for selectively opening an aperture in the resonator.
8. The gas turbine engine of claim 1 , wherein the bleed valve is located radially inward relative to an axis of rotation of the gas turbine engine from the resonator.
9. The gas turbine engine of claim 1 , wherein the slider is configured to slidably engage an inner surface of the body portion.
