A Fluidic Compressor Bleed Control

Abstract

An experimental compressor air powered fluidic jet engine compressor bleed control is described and test results are shown. The control must close the bleed valves at scheduled pressure ratios, provide a reset for the opening pressure ratio schedule, and an override for fast engine deceleration. It must operate over a wide range of pressures, pressure ratios and temperatures. Satisfactory performance is indicated at all conditions.
