A Voice Coil Actuated Air Valve for Use In Compressor Forced Response Testing
نویسنده
چکیده
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 (0.16 lbm/s) with a maximum valve throat area of 41 mm (0.064 in.), a 689 kPA (100 psid) pressure difference across the valve, and 20 C, (68 F) air supply. The valve was developed with inexpensive, off-the-shelve 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 8 of these valves in the compression system of a jet engine is discussed.

متن کاملExperimental application of extremum seeking on an axial-flow compressor
We show an application of the method of extremum seeking to the problem of maximizing the pressure rise in an axial flow compressor. First we apply extremum seeking to the Moore–Greitzer model and design a feedback scheme actuated through a bleed valve which simultaneously stabilizes rotating stall and surge and steers the system towards the equilibrium with maximal pressure. Then we implement ...
