Paper Abstract

A 0-450 Hertz bandwidth, voice coil actuated, proportional sleeve valve is designed to modulate air mass flow by controlling the throat area of a choked flow. The valve was designed to deliver a mass flow of 0.072 kg/s with a maximum valve throat area of 41 mm2, a 689 kPA pressure difference across the valve, and 20 degree(s)C, air supply. The valve was developed with inexpensive, off-the-shelf components for use in ground-based forced response testing of compression systems. The design and operation of the valve are discussed and experimental test data of a prototype valve and air injector are compared to a mathematical model. Implementation of a set of eight of these valves in the compression system of a jet engine is discussed.
