现有模型飞机的结构有两种一种是传统结构即用木材做成构架，外面用热缩膜等蒙皮，不仅结构复杂，成本高，模型抗冲击性差，而且要用掉大量宝贵的木材。下面来简单了解下吧。
There are two kinds of structures of the existing model aircraft. One is the traditional structure, that is, the frame is made of wood, and the outside is covered with heat shrinkable film. Not only the structure is complex, the cost is high, and the impact resistance of the model is poor, but also a lot of valuable wood is used. Now let's have a brief understanding.
结构是用泡沫塑料切割成形或直接用模具发泡成形，切开后里面衬上木构架再表面蒙皮而成，结构同样复杂，而且模型重量偏大强度差。
The structure is formed by cutting foamed plastic or directly foaming with a mold, lining the inside with a wooden frame and then skinning the surface. The structure is also complex, and the weight of the model is too large and the strength is poor.
型飞机由机身、机翼、尾翼、操纵系统及起落架组成，机身由主梁、挡板或涂层、连接件、前段填芯、加强件、左右侧板及机身尾段组成，两根主梁及左右侧板通过若干个连接件连接成一个整体，连接件线与机身线垂直，主梁前端构成了发动机架，上装发动机及油箱等。
The aircraft is composed of fuselage, wing, tail, control system and landing gear. The fuselage is composed of main beam, baffle or coating, connectors, front section core filling, stiffeners, left and right side plates and fuselage tail. The two main beams and left and right side plates are connected into a whole through several connectors. The center line of the connectors is vertical to the center line of the fuselage. The front end of the main beam forms an engine frame, loaded with engines and fuel tanks, etc.
主梁上钻有孔的地方均装有加强件，以保证主梁的强度，机身前段的内部空间内填充有填芯，并留有安装接收系统的空间，填芯的前面装有挡板或涂层，以防止发动机油料侵蚀，后面与机身尾段相接触。
The places where holes are drilled on the main beam are equipped with stiffeners to ensure the strength of the main beam. The internal space of the front section of the fuselage is filled with cores, and the space for installing the receiving system is reserved. The front of the cores is equipped with baffles or coatings to prevent the erosion of engine oil, and the back is in contact with the tail section of the fuselage.
机身尾段上开有槽并与两主梁的尾段相配合，用蒙皮将两者包裹成一个整体，机身尾段的前端在左右侧板的内侧并与侧板重叠配合，尾部开有水平尾翼及垂直尾翼安装槽，水平尾翼安装槽下表面与机身主梁上表面在同一平面上。
The tail section of the fuselage is slotted and matched with the tail sections of the two main beams, and the two are wrapped into a whole with skin. The front end of the tail section of the fuselage is on the inner side of the left and right side plates and overlapped with the side plates. The tail is provided with horizontal tail and vertical tail installation slots, and the lower surface of the horizontal tail installation slot is on the same plane as the upper surface of the main beam of the fuselage.
大型航天模型厂家知道机翼由机翼主板，前部半箱形主梁，后部翼肋，加强带及上反角套箱组成，机翼由机翼主板将前部半箱形主梁及后部翼肋包裹围成，半箱形主梁由立梁和前部上弧组成半箱形整体结构。
Large aerospace model manufacturers know that the wing is composed of wing main board, front half box girder, rear wing rib, reinforcing belt and upper anti angle sleeve box. The wing is wrapped by wing main board, and the front half box girder and rear wing rib are enclosed. The half box girder is composed of vertical beam and front upper arc to form a half box integral structure.
其内有若干个前翼肋即半箱形梁的加强隔板，后部有若干个卡槽，后部翼肋横截面为工字形，前部有凸橼并与卡槽相配合，机翼主板为一整块，在前缘处弯折后分别和半箱主梁及后部翼肋的上下部份粘合再在后缘处重叠粘合。
There are several front wing ribs in it, that is, the reinforced diaphragm of the half box girder, and several clamping slots at the rear. The cross section of the rear wing rib is I-shaped, and the front part is convex and matched with the clamping slots. The wing main board is a whole piece, which is bent at the front edge and bonded with the upper and lower parts of the half box girder and the rear wing rib respectively, and then overlapped and bonded at the rear edge.
翼尖是由机翼主板上下部份在尖部重叠粘合后整形而成，整个机翼前后缘及翼尖均粘贴有加强带以保证机翼粘接及强度，上反角套箱为一整体箱形结构，其内腔和机翼根部外表面相配合，左右机翼分别插入上反角套箱内腔并粘合。
The wing tip is shaped by overlapping and bonding the upper and lower parts of the wing main board at the tip. The front and rear edges of the whole wing and the wing tip are pasted with reinforcing strips to ensure the adhesion and strength of the wing. The upper anti corner box is an integral box structure, and its inner cavity matches the outer surface of the wing root. The left and right wings are inserted into the inner cavity of the upper anti corner box and bonded.
