Abstract: A three stream aspirator includes an upstream passage for receiving and discharging a motivator stream, a low pressure passage for receiving and discharging a low pressure stream, and a Venturi for receiving and discharging the motivator stream and for drawing the low pressure stream through the low pressure passage. The aspirator body also includes a mixing passage for receiving and mixing the motivator stream and the low pressure stream, and a first aspirator outlet, located at the end of the mixing passage, configured to discharge the mixed stream from the aspirator. The aspirator body further includes an isolated passage for receiving a high pressure stream, wherein the high pressure stream is isolated from any other stream while within the aspirator; and a second aspirator outlet, adjacent to the first aspirator outlet, from which the high pressure stream is discharged.

Abstract: A particle separator comprises a vessel, a fluid inlet, a fluid swirl passage, a scupper cavity, a first fluid outlet, and a second fluid outlet. The vessel includes a vessel sidewall extending between a vessel top side and a vessel bottom side. The fluid swirl passage includes a first passage end in communication with a fluid inlet disposed on the vessel top side. A second passage end is in communication with a vessel swirl cavity defined at least in part by an inner surface of the vessel sidewall. The scupper cavity includes a scupper entrance disposed along the inner surface of the vessel sidewall, and is spaced circumferentially apart from the second passage end. The first fluid outlet is in communication with the scupper cavity and disposed on the vessel bottom side. The second fluid outlet is disposed above the first fluid outlet in communication with the vessel swirl cavity.

Abstract: A precooler for an aircraft engine system includes a precooler core and a precooler inlet to direct a compressor bleed flow into the precooler core to cool the compressor bleed flow. The precooler further includes a precooler outlet to direct the compressor bleed flow from the precooler to a selected component of the aircraft engine system and a precooler bleed port through which a portion of the compressor bleed flow is diverted to a secondary component of the aircraft engine system. The precooler bleed port is oriented such that flow entering the precooler bleed port must substantially reverse direction from a direction of the compressor bleed flow through the precooler.
