Under the condition of artificial freezing, experiments of de-icing on airfoil using a heated dual synthetic jet actuator have been carried out.The practicability of de-icing using the heated dual synthetic jet actuator has been proved and the influence of the environment temperature and ventilating angle was then studied respectively.Compared to the heated airfoil model without a dual synthetic jet actuator, the dual synthetic jet actuator helps to decrease the de-icing time by about 25.0% to 36.4%.As the dual synthetic jet actuator promotes heat diffusion and thus helps accelerating the de-icing process on the airfoil model, it is thus preferable to use the heated dual synthetic jet in flight de-icing.What''s more, experiment also reveals that the de-icing effect is better when the ventilating angle is close to 90°.%在人工结冰条件下,利用合成双射流激励器与电热贴片形成合成热射流激励器,开展合成热射流机翼除冰试验,验证合成热射流机翼除冰方案的可行性,同时分别研究除冰的环境温度和射流出口通道开缝角度对机翼除冰效果的影响.研究表明:合成热射流方案与纯加热方案相比,除冰时间能够减少25.0%~36.4%.合成双射流能够促进热能的扩散,加速机翼表面开缝附近冰的融化,使得合成热射流有较好的除冰效果,且出口通道开缝角度与表面积冰越垂直,加速除冰效果越明显.
