Abstract

A multi-port flow control actuator (MPFCA) for controlling a fluid flow across an aerodynamic surface includes a housing having an internal chamber and a first and second fluid passageway connected to the internal chamber. A first port is connected to the first fluid passageway and a second port is connected to the second fluid passageway. An oscillating membrane is positioned in the internal chamber that causes fluid to enter one of the first port and second port and exit one of the first port and second port when the oscillating membrane is oscillated. A fluid line may be provided for injecting a supply fluid such as a fuel or oxidizer into the internal chamber volume. The first and second port may be positioned along a line that is at an angle, parallel or perpendicular to a fluid flow to create different flow effects.
