摘要

在逆向建模过程中

为提高获取模型的准确性并加快设计效率

提出一种基于面积法的翼型叶片逆向建模方法。通过对翼型设计方程的积分运算和几何加减推导出一系列含有翼型参数的面积公式

并将翼型轮廓划分为4个特殊区域进行面积测量

然后将得到的面积值代入面积公式中来获得翼型的参数和型号。根据翼型的型号和设计方程正向设计出翼型截面的轮廓

再通过放样操作将不同截面的翼型轮廓连接获得翼型叶片模型。通过与型号变动的翼型截面轮廓面积进行比较

验证该方法的可行性。该方法将翼型的面积元素引入到逆向建模中

简化了对于翼型数据的获取。面积公式是由设计方程推导而来

计算过程简单快捷

降低了误差的同时

加快了逆向建模的速度。翼型型号的识别使获得的模型更符合设计原理

并为后续的优化设计提供了结构信息。

Abstract

During the reverse modeling process

an airfoil blade reverse modeling method based on area method is proposed to improve model accuracy and expedite design efficiency. A series of area formulas containing airfoil parameters are derived through integral operations

and geometric addition and subtraction based on the airfoil design equations. The airfoil contour is divided into four special regions and the area of these four regions is measured. The obtained areas are substituted into the area formulas to obtain the airfoil's parameters and type. The airfoil cross-section contour is forward designed through the type and design equations of airfoil

and the airfoil contours of different cross-sections are connected through lofting operation to obtain the airfoil blade model. By comparing the obtained results with the airfoil cross-sectional areas of variant models

the feasibility of this method is verified. The area elements of airfoil are introduced into reverse modeling in this method

which simplifies the acquisition of airfoil data.The area formulas are derived from design equations

and their calculation process is straightforward and fast

which can not only reduce errors but also accelerate the reverse modeling process. The identification of airfoil's type makes the obtained model more aligned with its design principles and provides structural information for subsequent optimization designs.
