摘要
飞机结冰理论和致灾机制对预防结冰事故和提高飞行性能至关重要。本文系统地总结了不同冰形条件及特殊机翼流场特性的研究进展,指出实际三维冰形具有复杂、多样的结构特征,与分离流和湍流结构的耦合作用机制有待进一步深入研究;过冷大液滴条件下的特殊机翼的气动性能分析是未来重要的研究方向;湍流场分析侧重识别结冰翼型流场不稳定性特征及多尺度结构相互作用机制。探索积冰—流场耦合机制,对提出多因素、多参数、多尺度结冰预测与计算模型具有参考价值。
The theory of aircraft icing and its disaster mechanisms are crucial for preventing icing accidents and enhancing flight performance.The research progress on the flow field characteristics under different icing conditions and special wing configurations are systematically summarized in this paper.It is pointed out that,the actual threedimensional ice shapes are complex,have multiple structural features,and coupling mechanisms with separated flow and turbulence structures should be further studied.The aerodynamic performance analysis of special wings under supercooled large droplet conditions is the significant future research direction.Turbulence field analysis focuses on identifying instability characteristics of the icing wing flow field and multi-scale structural interaction mechanisms.Exploring the ice-flow coupling mechanism is of reference value for developing multi-factor,multi-parameter,and multi-scale icing prediction and computational models.
