“…In summary, there are various existing anti/de-icing technologies, but they all have their own shortcomings, so new anti/de-icing technologies are emerging. For example, plasma anti/de-icing technology has become a research hotspot [14][15][16][17][18][19][20]. With in-depth research of dielectric-barrier discharge (DBD) plasma in the field of active flow control, its remarkable thermal properties have attracted attention in recent years and started to be widely used in plasma anti/deicing technology [21,22], which plays an important role in the field of plasma anti/de-icing.…”

“…In 2021, the team proposed a de-icing strategy that combines plasma synthetic jets with electrical heating, using electrical heating to break the bonding force of the ice first, and then turning on the PSJA for de-icing [19]. To meet the requirements of inflight de-icing, Gao et al [20] adapted the structure of the PSJA, designed a new plasma striker for experimental validation of de-icing, and investigated the effect of the parameters of the moving parts on the performance of ice breaking. The ability of the colliding rod PSJA to de-ice has been verified, but the study of an individual actuator to break the ice is not detailed enough.…”

Since flight accidents due to aircraft icing occur from time to time, this paper proposes an array of impact rod type plasma synthesis jet de-icing method for aircraft icing problem. The impact rod type plasma synthesis jet actuator is based on the traditional plasma synthesis jet actuator with an additional impact rod structure for better de-icing in the flight environment.In this paper, we first optimize the ice-breaking performance of a single impact rod type plasma synthesis jet actuator, and then conduct an array of impact rod type plasma synthesis jet ice-breaking experiments to investigate the relationship between crack expansion and discharge energy, ice thickness, and group spacing. The results show that the impact force and impulse of a single impact rod type plasma synthesis jet actuator are proportional to the discharge energy, and there exists a threshold energy Qmin for a single actuator to break the ice, which is proportional to the ice thickness.Only when the discharge energy reaches above Qmin can the ice layer produce cracks, and at the same time, the maximum radial crack length produced during the ice breaking process is proportional to the discharge energy. When the ice is broken by an array of impact rod plasma synthetic jet actuator, the discharge energy and the group spacing together determine whether the crack can be extended to the middle region of the actuator. When the group spacing is certain, increasing the energy can increase the intersection of cracks in the middle region, and the ice fragmentation degree is increased and the ice breaking effect is better. At the same time, the energy estimation method of ice breaking by array of impact rod type plasma synthesis jets is proposed according to the law when a single actuator is breaking ice.
