摘要
在复杂的气象条件下飞机机翼容易出现结冰现象,结冰会导致机翼的气动布局改变,恶化飞机的气动特性与飞行性能,影响飞行安全,因此开展飞机机翼的防/除冰技术研究意义重大。介绍了机翼结冰的主要部位、典型冰形及其危害,采用FLUENT软件计算分析了2种典型翼型NACA23012和NACA0012结冰前后的气动特性变化,总结了机翼结冰对飞机气动特性的影响规律,阐述了机翼防/除冰技术的原理、优缺点及近年的研究进展,分析了机翼防/除冰技术未来的发展方向。
In some particular flight environment, ice is easy to adhere to the airfoil and change the aerodynamic configuration of the airfoil. Icing will influence the aerodynamic characteristics and flight performance of the airfoil. Thus it is very important to carry out the research on anti-icing and de-icing technologies of airfoil. The major parts of icing, representative ice types on the airfoil and the damage of icing are introduced respectively in this paper. The aerodynamic characteristics of airfoils NACA23012 and NACA0012 before and after icing are analyzed using the software of FLUENT. Based on them, the principle, advantage, disadvantage and research advances of airfoil anti-icing and de-icing technologies are expounded; The development of the airfoil anti-icing and de-icing technologies is also prospected.
