摘要
机翼结构的型式取决于机翼的平面形状、相对厚度、翼载荷、开口等诸多因素。本文对现有飞机机翼结构型式和相关参数进行统计分析,寻找它们之间可能存在的内在关系,得到了相对厚度与最大飞行速度的经验公式,以及不同机翼结构型式的相对厚度和相对载荷的取值范围。并对结构选型的其他因素进行了简单的探讨。这些统计结果为现代飞机机翼结构选型提供了一些参考。
Wing planform,airfoil relative thickness,wing loading,opening and many other factors determine wing configuration.Statistical analysis for existing wing configuration and relevant parameters is made to find the potential relations among these parameters.3 experiential expressions related to airfoil relative thickness and maximum flying speed,as well as the value limits of some parameters have been obtained.Additionally,other factors for configuration selection are discussed.These expressions and data are proved to be referenced for configuration selection of wing.
