摘要:

飞机结冰威胁飞行安全,针对这一问题,通过记录结冰动态过程及测量表面温度变化对比研究了布置在NACA0012翼型上的等离子体激励、电阻丝电热及石墨烯电热在结冰风洞中的防冰性能。结果表明:在输入功率相同的情况下,等离子体激励和石墨烯电热均能有效地实现防冰,而电阻丝电热在无热源区域无法完全预防结冰。红外测量结果表明:石墨烯电热膜加热后表面最高温度低于其他2种方法。然而,由于其均匀的加热特性,整个加热表面的最低温度保持在0 ℃以上,足以防止结冰。对于等离子体激励和电阻丝电热,二者表面的温度分布具有不均匀性,通过散热性能对比,等离子体激励要高于电阻丝电热。等离子体激励通过在近壁面气体放电直接加热激励器周围的来流冷空气与过冷水滴,而电阻丝加热对绝缘介质的热传导性能差,无法有效增加周围热量致使容易在无热源区域结冰。

Abstract:

Aircraft icing threatens flight safety. To solve this problem, this paper makes a comparative study of the anti-icing performance of plasma actuation, resistance wire electric heating and graphene electric heating arranged on the NACA0012 airfoil in the icing wind tunnel by recording the icing dynamics process and the temperature variation of the area. The results show that with the same input power, both plasma actuation and graphene electric heating can effectively prevent icing, while resistance wire electric heating cannot completely prevent ice accumulation in the area without heat source. The infrared measurement results show that the maximum surface temperature of graphene electrothermal film after heating is lower than that of the other two methods. However, due to its uniform heating properties, the minimum temperature of the entire heated surface remains above 0 ℃, which is sufficient to prevent icing. For plasma actuation and resistance wire electric heating, the temperature distributions on their surfaces are not uniform. The heat dissipation performance of plasma actuation is higher than that of resistance wire electric heating. Plasma actuation directly heats the incoming cold air and supercooled water droplets around the actuator by gas discharge near the wall, while resistance wire electric heating has poor heat conduction in the insulating medium and thus cannot effectively increase the surrounding heat, resulting in icing easily in the area without heat source.
