Engine inlet air particle separator with active flow control
First Claim
1. An engine inlet air particulate separator, comprising:
- a separator body comprising an arcuate body portion having a bight region;
a divided region downstream from the bight region and in fluid communication with the arcuate body portion;
a splitter located in the divided region, the splitter creating a first region and a second region; and
a mass active flow device in fluid communication with an interior of the separator body.

Abstract
An engine inlet air particulate separator that uses zero mass active flow control devices, and methods of using the same, are provided. The separator has a separator body that has an arcuate portion with a bight region. The separator body may have an angle α between centerlines in the range from about 115° to about 85°. The separator body separates into a bypass conduit and a primary air conduit, separated from each other by a splitter, downstream from the bight region, which is in fluid communication with the arcuate portion. A zero mass active flow device is in fluid communication with a third region of the separator body which is located proximate a point where the air stream would otherwise have separated from an inner wall of the particle separator.

9. An engine inlet air particulate separator, comprising:
-
a hollow separator body comprising; an elongate curved body portion configured for air flow there through, the elongate curved body portion comprising a bight region; a divided region downstream from the bight region and in fluid communication with the elongate curved body portion; a splitter located in the divided region, the splitter oriented such that when air flows through the hollow separator body, the splitter divides the air flow into the divided region into a first stream and a second stream; and at least one zero mass active flow device in fluid communication with an interior of the hollow separator body, the zero mass active flow device emitting pulses into the hollow separator body; whereby, when incoming air containing particulates flows through the hollow separator body and the zero mass active flow device emits pulses into the hollow separator body, the splitter separates the incoming air into a first steam containing a higher mass of particulates and a second stream substantially free of particulates. - View Dependent Claims (10, 11, 12, 13, 14, 15)
