Concepts and technologies described herein provide for the creation of an actuating fluid flow utilizing a multi-stage actuator. According to one aspect of the disclosure provided herein, a fluid actuation system includes at least two stages (110), each stage having a plenum (112) and one or two diaphragms (206) acting on the plenum to create an actuating fluid flow (108). The diaphragms of each stage may be substantially aligned along an axis. The actuating flow is aggregated between stages arid expelled into a fluid flow to be controlled, According to various aspects, the diaphragms may include piezoelectric discs.
