摘要： A compressor or pump is connected to a discharge plenum. The plenum includes a movable wall whose motion varies the volume of the plenum. The wall is connected to passive elements forming a spring-mass-damper system whose characteristics are selected to damp pressure fluctuations in the plenum which would give rise to pumping system instabilities. In another aspect of the invention, a compressor is connected to a discharge plenum which in turn is connected to an exit throttle. The throttle includes a movable portion whose motion varies the throttle area. The movable portion is connected to passive elements forming a spring-mass-damper system selected to damp pressure fluctuations in the plenum. In another embodiment, the plenum communicates with a fixed area throttle and a variable area throttle. The variable area throttle includes a movable portion connected to passive elements selected to damp pressure fluctuations in the plenum. Aerodynamic surge control is effected by coupling a second Helmholtz resonator to the plenum.
