1. A system for control of a fluid flow, comprising: an array of interdependent fluidic actuators, each comprising a chamber, a flow control port, and opposite side walls configured to expand apart and contract together to flow a control fluid through the flow control port in response to an input, wherein adjacent actuators in the array of interdependent fluidic actuators are integrally coupled together via a common side wall of the opposite side walls. 2. The system according to claim 1, wherein the array of interdependent actuators comprise first and second sets of actuators alternating one after another, the first set of actuators includes active control mechanisms configured to move the opposite side walls, and the second set of actuators are passively operative via movement of the opposite side walls by the first set of actuators. 3. The system according to claim 1, wherein the common side wall is configured to move alternately between the chambers of the adjacent actuators. 4. The system according to claim 1, wherein the common side wall is configured to induce opposite flows through the flow control ports of the adjacent actuators. 5. The system according to claim 1, wherein the opposite side walls including the common side wall are configured to alternate between inwardly curved and outwardly curved geometries. 6. The system according to claim 1, wherein the interdependent fluidic actuators comprise piezoelectric devices disposed on the opposite side walls about the chambers. 7. The system according to claim 1, wherein the array of interdependent fluidic actuators is disposed along an aerodynamic surface. 8. The system according to claim 1, wherein the array is disposed on an engine, an airfoil, an aircraft, a duct, a watercraft, an automobile, or combinations thereof. 9. The system according to claim 1, wherein the input comprises an alternating voltage that is either pulsed or continuous. 10. The system according to claim 1, wherein the array of interdependent fluidic actuators comprise a first set of actuators synchronized with one another and a second set of actuators synchronized with one another in an opposite phase from the first set, and the first and second sets are integrally coupled together in an alternating arrangement having the common side wall disposed between the adjacent actuators in the first and second sets. 11. An aircraft, comprising: an aircraft body;a core engine coupled to the aircraft body;a system configured to control a flow of a fluid associated with the aircraft, comprising an array of interdependent fluidic actuators, each comprising a chamber, a flow control port, and opposite side walls configured to expand apart and contract together to flow a control fluid through the flow control port in response to an input, wherein adjacent actuators in the array of interdependent fluidic actuators are integrally coupled together via a common side wall of the opposite side walls. 12. An engine, comprising: a core engine;a system for control of a flow of a fluid associated with the engine, comprising an array of interdependent fluidic actuators, each comprising a chamber, a flow control port, and opposite side walls configured to expand apart and contract together to flow a control fluid through the flow control port in response to an input, wherein adjacent actuators in the array of interdependent fluidic actuators are integrally coupled together via a common side wall of the opposite side walls.
