摘要
结冰严重影响飞行安全,为保证安全飞行,飞机采取结冰防护系统作为重要保障措施。本文介绍了一种基于脉冲技术的电加热除冰系统,阐述了其基本原理和物理模型。经过理论建模,借助数值方法,计算得到了脉冲加热功率、能量消耗和加热时间之间的关系。根据计算结果,分析了表面温度随工作时间的变化趋势,为进一步研究脉冲电加热除j水系统提供了参考。
Aircraft safety level is seriously degraded by in-flight icing.In order to prohibit this negative effect,ice protection system is employed to ensure aircraft flight safety during icing conditions.An electro-thermal de-icing system based on pulse technology is introduced here,including the basic operating principle and the physical model.A numerical method is adopted to analyze the de-icing performance.The power and energy consumption against different pulsing times are obtained by the numerical method.Furthermore,a detailed explanation tells the icing skin surface temperature versus heat time,and it can give a valuable reference for deeper research on pulse electro-thermal de-icing system.
