The actuators operates close to first resonance frequencies and was supply by a harmonic power input. The characteristic velocity as function of the input real power were measured. On this basis, approximate values of momentum flux, kinetic energy and efficiency were determined. The paper presented benefits of using synthetic jets actuator with two diaphragms. The used of two diaphragms increase the value of, momentum flux about 79.62%, kinetic energy about 140.72% and energetic efficiency about 140.72% relative to actuator with one undamped diaphragm by the same value of real power input.
