COMPRESSOR TIP GAP FLOW CONTROL USING PLASMA ACTUATORS

摘要

A plasma generator for delaying the onset of rotation stall by tip gap flow control in, for example, an axial flow compressor is disclosed. The tip gap flow control system includes a housing surrounding a rotor of blades and having an inner wall. At least one plasma generating device is coupled to the inner wall of the housing and circumscribes at least a portion of the rotor of blades. A power supply is electrically coupled to the plasma generating device such that when the power supply energizes the plasma generating device, the axial momentum of a fluid flow between the inner wall of the housing and the tips of the rotor of blades in increased in the direction of the fluid flow.
