一般情况下，有关厂家制作飞机模型之前，要确定飞机的机型，是战斗机，还是滑翔机，客机，预警机？然后计算飞机的机身，机翼，副翼的面积。机翼常见的形状又分为：矩形翼、后掠翼、三角翼和纺锤翼（椭圆翼）。
Generally, before making aircraft models, relevant manufacturers should determine whether the aircraft model is a fighter, a glider, an airliner or an early warning aircraft? Then calculate the area of the fuselage, wings and ailerons of the aircraft. Common wing shapes are divided into rectangular wing, swept wing, delta wing and spindle wing (elliptical wing).
模型飞机能不能飞起来，好不好飞，起飞降落速度快不快，翼载荷非常重要。一般讲，滑翔机的翼载荷在35克/平方分米以下，普通固定翼飞机的翼载荷为35-100克/平方分米，像真机的翼载荷在100克/平方分米、确定副翼的面积机翼的尺寸确定后，就该算出副翼的面积了。（具体情况具体分析数据）
Whether the model aircraft can fly, whether it is easy to fly, and whether the takeoff and landing speed is fast, wing load is very important. Generally speaking, the wing load of a glider is less than 35 g / square decimeter, and the wing load of an ordinary fixed wing aircraft is 35-100 g / square decimeter. For example, the wing load of a real aircraft is 100 g / square decimeter. After determining the area of the aileron and the size of the wing, it is time to calculate the area of the aileron.

确定位置的确定非常重要，太靠前，飞机就头沉，起飞降落抬头困难。飞机外形设计是飞机设计过程中不可缺少部分，在提高飞机速度方面起着不可替代的作用。
It is very important to determine the position of the center of gravity. If the center of gravity is too forward, the aircraft will sink, and it is difficult to take off and land. Aircraft shape design is an indispensable part of aircraft design process and plays an irreplaceable role in improving aircraft speed.
随着空气动力学的发展和各种技术的介入，飞机的外形逐渐向流线型和多层机翼等方向演变，大大降低了空气阻力、加大了推力及升力，并提高了飞机的灵活度，数控技术在飞机加工制造方面的应用和发展，使得飞机制造走向高精度化、率化和自动化。
With the development of aerodynamics and the intervention of various high-end technologies, the shape of the aircraft has gradually evolved to streamline and multi-layer wings, which has greatly reduced the air resistance, increased the thrust and lift, and improved the flexibility of the aircraft. The application and development of numerical control technology in aircraft processing and manufacturing has made aircraft manufacturing move towards high precision, high efficiency and automation.
所有的图纸内容都全部敲定后，就是通过数控加工了。大特征有两点:一是可以很大地提高精度,包括加工质量精度及加工时间误差精度;二是加工质量的重复性,可以稳定加工质量,保持加工零件质量的一致，以及数控加工具有提高生产效率和高度准确性。
After all the drawings are finalized, they are processed by numerical control. There are two major features: first, it can greatly improve the accuracy, including the accuracy of machining quality and machining time error; Second, the repeatability of processing quality can stabilize the processing quality, maintain the consistency of the quality of processed parts, and NC processing can improve production efficiency and high accuracy.
大型飞机模型等产品，从开始的图纸设计，到后的模型安装，每一个环节都是紧密衔接的。外形的仿真度，飞机模型的自重，平衡点，都是要考虑到位的。作为一个设计师，真正的体会到什么是差之毫厘谬以千里。
Large aircraft models and other products are closely linked from the initial drawing design to the subsequent model installation. The simulation degree of the shape, the dead weight of the aircraft model and the balance point should be considered in place. As a designer, I really realize what is the difference.
