A Voice Coil Actuated Air Valve for Use In Compressor Forced Response Testing

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… CONTINUE READING
