摘　　要：等离子体激励具有电离效应、气动效应和热效应,可被用于飞行器防除冰。背面电极的气隙构型对于交流供电的沿面介质阻挡放电(SDBD)防除冰激励器的单周期放电次数和放电电荷分布均有影响,电源频率也为影响激励器温升的重要因素。目前对于交流SDBD温升效果的研究均是基于背面电极无气隙的构型,且缺乏激励频率大于15kHz的高频条件。为此制作了背面电极有气隙和无气隙的对照构型,在35~55kHz的高频范围内,采用电学特性、红外测温、放电形态相结合的方式研究了交流SDBD防除冰激励器温升特性。结果表明:施加相同的电压或频率时,背面电极有气隙构型的SDBD激励器的裸露正面最高温度相比无气隙构型激励器可提高至151.51%;背面电极气隙的存在也可以使激励器正面尤其是正面等离子放电反方向的温升区域扩大;增加频率使交流SDBD激励器的温度非线性提高,有助于降低高压击穿风险。Dielectric barrier discharge produces ionization effect,aerodynamic effect,and thermal effect,and therefore can be used for aircraft anti-icing and deicing.The air-gap on the rear electrode influences both the discharge times per cycle and the charge distribution for Surface Dielectric Barrier Discharge(SDBD)actuators with Alternating Current power supply(AC-SDBD),and frequency is also an important factor affecting temperature rise of the actuator.However,current research on the temperature rise effect of AC-SDBD is based on the configuration without air-gaps on the rear electrode,and lacks high excitation frequencies above 15 kHz.The contrast configurations with and without air-gaps on the rear electrode are built.In the high frequency range of 35-55 kHz,the temperature rise characteristics of AC-SDBD are studied using the electrical characteristics,infrared temperature measurement,and discharge morphology.The results show that the maximum temperature on the exposed surface of the AC-SDBD actuator with air-gap on the rear electrode is 151.51%as much as that without air-gap when the same voltage or frequency is applied.The existence of the air-gap on the rear electrode can enlarge the temperature rise area on the exposed surface of the actuator,particularly in the direction opposite to the discharge.The temperature increases nonlinearly with the rise of frequency,thereby reducing the risk of high voltage breakdown.
