Abstract
A system and method of using a variable geometry ejector for a bleed air system using integral bleed pressure feedback which utilizes a minimal amount of high-pressure air, thus improving the overall engine cycle performance and is easily adaptable to a multitude of different engine types. This is accomplished through the use of a variable ejector using downstream pressure feedback to control the flow and pressure.
