Abstract

The invention discloses a composite plasma synthetic jet exciter for aircraft attitude regulation and control. The composite plasma synthetic jet exciter comprises an exciter body, a discharge cavity, a cathode needle electrode, an anode needle electrode, an insulating dielectric layer, an exposed electrode, a buried electrode and a jet hole. During working, an electric arc is formed between the needle electrodes on the two sides of the discharge cavity, and gas in the discharge cavity is instantly heated and flows to the jet hole; meanwhile, gas discharges on the surface of a plate-shaped electrode at the top of the exciter, generated ions are induced by an electric field to conduct secondary acceleration on gas flow, and high-speed jet flow is sprayed outwards from a jet flow outlet. The structure and characteristics of a traditional plasma synthetic jet exciter are not damaged, the composite plasma synthetic jet exciter is formed, the performance of the traditional exciter is effectively improved, and the generated torque can effectively meet the requirement for attitude regulation and control of an aircraft.
