Active flow control technology is a frontier and transformative technology in the aviation field of the 21st century. Dual synthet-ic jet (DSJ) is a new type of active flow control technology with characteristics of high energy efficiency, strong environmental adaptability, and wide control range, and it is expected to fully assist in the performance improvement of current aircraft and the revolutionary development of next-generation aircraft. This paper systematically summarizes the theory, technical characteristics, and the latest research progress of DSJ in empowering aviation technology. Through twenty-year researches, the DSJ theory system based on the "enhancement" effect, "vector" effect, and " augmentation / self-support" effect existing between double synthetic jets with different phases has been formed. And the DSJ technology system with characteristics of energy efficiency doubling, full electric vectoring, and cross-medium working ability has been developed. DSJ has shown great application pro-spects in aspects of aircraft aerodynamics, power, flight control, flight safety, thermal control and environment control, underwa-ter flow control and so on. Among them, rudderless flight control technology based on was selected as one of the major scien-tific and technological progress in China's aviation field. DSJ also supports the establishment of the first flow control technology professional committee in China (Flow Control and Thermal Management Branch of the Chinese Society of Aeronautics and Astronautics).
