一般情況下，有關廠家制作飛機模型之前，要確定飛機的機型，是戰斗機，還是滑翔機，客機，預警機？然后計算飛機的機身，機翼，副翼的面積。機翼常見的形狀又分為：矩形翼、后掠翼、三角翼和紡錘翼（橢圓翼）。
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).
模型飛機能不能飛起來，好不好飛，起飛降落速度快不快，翼載荷非常重要。一般講，滑翔機的翼載荷在35克/平方分米以下，普通固定翼飛機的翼載荷為35-100克/平方分米，像真機的翼載荷在100克/平方分米、確定副翼的面積機翼的尺寸確定后，就該算出副翼的面積了。（具體情況具體分析數據）
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.

確定位置的確定非常重要，太靠前，飛機就頭沉，起飛降落抬頭困難。飛機外形設計是飛機設計過程中不可缺少部分，在提高飛機速度方面起著不可替代的作用。
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.
隨著空氣動力學的發展和各種技術的介入，飛機的外形逐漸向流線型和多層機翼等方向演變，大大降低了空氣阻力、加大了推力及升力，并提高了飛機的靈活度，數控技術在飛機加工制造方面的應用和發展，使得飛機制造走向高精度化、率化和自動化。
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.
所有的圖紙內容都全部敲定后，就是通過數控加工了。大特征有兩點:一是可以很大地提高精度,包括加工質量精度及加工時間誤差精度;二是加工質量的重復性,可以穩定加工質量,保持加工零件質量的一致，以及數控加工具有提高生產效率和高度準確性。
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.
大型飛機模型等產品，從開始的圖紙設計，到后的模型安裝，每一個環節都是緊密銜接的。外形的仿真度，飛機模型的自重，平衡點，都是要考慮到位的。作為一個設計師，真正的體會到什么是差之毫厘謬以千里。
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.
