为研究飞行器翼面积冰预测问题,通过对积冰形成机理的分析,提出了基于经典Messinger模型的积冰表面传质传热的改进模型;通过引入对多段翼空气流场的插值计算,建立了多段翼翼面积冰预测模型;考虑防冰系统向翼面控制体带入的等效热功率,提出了防冰条件下的积冰预测方法.通过对算例的分析对比,数值模拟计算结果与实验数据基本吻合,表明本文提出的结冰计算模型合理,能够用来进行积冰预测分析,为进一步研究翼面结冰后的飞行动力学问题及防除冰系统的设计奠定了基础.
In order to study the prediction of aircraft wing area ice, an improved model based on the classical Messinger model for mass transfer heat transfer is proposed by analyzing the formation mechanism of ice accumulation. By introducing the interpolation calculation of air flow field of multiple wings, Considering the equivalent thermal power brought by the anti-icing system to the airfoil control body, an ice-predicting method is proposed in this paper.According to the analysis and comparison of the examples, numerical simulation results and experiments The results show that the icing calculation model proposed in this paper is reasonable and can be used for prediction and analysis of ice accumulation, which lays the foundation for further research on the flight dynamics after icing and the design of ice protection system.
