近年来,计算技术和数控技术已开始应用于我国各飞机工厂。在飞机制造中,采用计算和数控技术,首先需要建立飞机外形的数学模型及编制外形计算程序系统。外形数学模型及计算程序系统,就如同常规工艺方法中的理论模线一样,作为外形传递的原始依据,它直接影响到整个飞机生产的质量和周期。常规工艺方法中,绘制模线的周期较长(歼击机一般需
In recent years, computational technology and numerical control technology have begun to be applied to various aircraft factories in China. In aircraft manufacturing, the use of computing and numerical control technology, first of all need to establish a mathematical model of aircraft shape and preparation of shape calculation system. Shape mathematical models and computational program systems, like the theoretical mold lines in conventional process methods, serve as the original basis for shape transfer and have a direct impact on the quality and cycle of the entire aircraft production. In the conventional process, the cycle of drawing the mold line is long (fighter usually needs
