摘要
在冰风洞中开展了结冰条件下NACA0012翼型的流向和展向分布等离子体射流防冰性能对比实验.设计加工了基于介质阻挡放电技术的流向和展向分布等离子体射流激励器并粘接于翼型表面,热电偶巧妙埋设于激励器下方以检测防冰效果.结果表明,展向分布等离子体射流激励器在裸露电极上方无法生成等离子体射流,故而会有明冰生成,防冰效果较差,而流向分布激励器在来流的作用下能够部分弥补这一缺陷,具有更好的防冰效果.
The anti-icing performances of streamwise and spanwise plasma jet actuators fixed on NACA0012 are compared in the icing wind tunnel.Streamwise and spanwise actuators are designed and installed on the model surface,and thermocouples are specially embedded beneath the actuator to detect the anti-icing effects.Experiment results indicate that the spanwisely installed actuator cannot generate plasma jets due to the installation position being above the exposed electrode,leading to icing and thus a poor performance of anti-icing,while the streamwisely installed actuator realizes anti-icing by contrast.
