摘　　要：在飞机舵面设计中 ,舵面翼型一般均选用可以在气动手册中查到的现成翼型 ,但舵面前缘外形一般需自行设计。本文采用双圆弧插值计算及计算机辅助设计等方法 ,先后建立对称翼型和不对称翼型舵面前缘的数学模型 ,给出光顺流畅 ,且便于数控加工制造的舵面前缘外形。这些方法已成功地应用在多种轻型低速飞机舵面设计中 。In control surface design, its airfoil is usually selected from an aerodynamic handbook, However, the outline of leading edge needs to be separately designed. In this paper, the bi-arcuate interpolating method and computer-aided design are used to model the leading edge of symmetry and asymmetry airfoils and to give easily numeric-control-machined and fairly smooth shapes of leading edge of airfoils. This technique has been successfully used in low speed light aircraft designs and provides satisfactory results.
