現(xiàn)有模型飛機的結構有兩種一種是傳統(tǒng)結構即用木材做成構架，外面用熱縮膜等蒙皮，不僅結構復雜，成本高，模型抗沖擊性差，而且要用掉大量寶貴的木材。下面來簡單了解下吧。

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.

結構是用泡沫塑料切割成形或直接用模具發(fā)泡成形，切開后里面襯上木構架再表面蒙皮而成，結構同樣復雜，而且模型重量偏大強度差。

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.

型飛機由機身、機翼、尾翼、操縱系統(tǒng)及起落架組成，機身由主梁、擋板或涂層、連接件、前段填芯、加強件、左右側板及機身尾段組成，兩根主梁及左右側板通過若干個連接件連接成一個整體，連接件線與機身線垂直，主梁前端構成了發(fā)動機架，上裝發(fā)動機及油箱等。

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.

主梁上鉆有孔的地方均裝有加強件，以保證主梁的強度，機身前段的內部空間內填充有填芯，并留有安裝接收系統(tǒng)的空間，填芯的前面裝有擋板或涂層，以防止發(fā)動機油料侵蝕，后面與機身尾段相接觸。

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.

機身尾段上開有槽并與兩主梁的尾段相配合，用蒙皮將兩者包裹成一個整體，機身尾段的前端在左右側板的內側并與側板重疊配合，尾部開有水平尾翼及垂直尾翼安裝槽，水平尾翼安裝槽下表面與機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.

大型航天模型廠家知道機翼由機翼主板，前部半箱形主梁，后部翼肋，加強帶及上反角套箱組成，機翼由機翼主板將前部半箱形主梁及后部翼肋包裹圍成，半箱形主梁由立梁和前部上弧組成半箱形整體結構。

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.

其內有若干個前翼肋即半箱形梁的加強隔板，后部有若干個卡槽，后部翼肋橫截面為工字形，前部有凸櫞并與卡槽相配合，機翼主板為一整塊，在前緣處彎折后分別和半箱主梁及后部翼肋的上下部份粘合再在后緣處重疊粘合。

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.

翼尖是由機翼主板上下部份在尖部重疊粘合后整形而成，整個機翼前后緣及翼尖均粘貼有加強帶以保證機翼粘接及強度，上反角套箱為一整體箱形結構，其內腔和機翼根部外表面相配合，左右機翼分別插入上反角套箱內腔并粘合。

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.
