## Simulation of heating control law of electro-thermal deicing of helicopter rotor blade

• 摘要: 电热防除/冰系统的控制涉及到电加热与外流场的传热耦合，计算较为复杂，可利用的数据资料较为稀少。为探索电热防/除冰系统工作时与外流场的耦合传热规律，建立了二维电热除冰的数学模型，该模型在Messinger模型和改进的焓法模型基础上耦合了外表面与环境的复杂换热以及融冰和重新结冰过程的相变换热；采用控制容积法对控制微分方程进行离散后，使用TDMA（Tri-Diagonal Matrix Algorithm）和ADI（Alternating Direction Implicit）方法对离散得到的线性方程组进行求解，进而得到了除冰表面温度分布，同时揭示了电热防/除冰系统的耦合传热规律；分析了不同结冰条件下，加热时间控制律和加热热流密度对除冰表面温度的影响。计算发现合理设计加热热流密度大小及分布和加热时间控制律，可实现电热除冰系统能源的高效利用，进而确保飞行安全。
