模型飛機一般與載人的飛機一樣，主要由機翼、尾翼、機 身、起落架和發(fā)動機五部分組成。

Model aircraft is generally the same as manned aircraft, which is mainly composed of wing, tail, fuselage, landing gear and engine.

1、機翼———是模型飛機在飛行時產(chǎn)生升力的裝置，并 能保持模型飛機飛行時的橫側(cè)安定。

1. Wing is a kind of device which can produce lift force and keep lateral stability of model aircraft in flight.

2、尾翼———包括水平尾翼和垂直尾翼兩部分。水平尾 翼可保持模型飛機飛行時的俯仰安定，垂直尾翼保持模型飛機飛行時的方向安定。水平尾翼上的升降舵能控制模型飛機的升 降，垂直尾翼上的方向舵可控制模型飛機的飛行方向。

2. Tail wing includes horizontal tail and vertical tail. The horizontal tail can maintain the pitch stability of the model aircraft while the vertical tail can maintain the directional stability of the model aircraft. The elevator on the horizontal tail can control the lift of the model aircraft, and the rudder on the vertical tail can control the flight direction of the model aircraft.

3、機身———將模型的各部分聯(lián)結(jié)成一個整體的主干部 分叫機身。同時機身內(nèi)可以裝載必要的控制機件，設備和燃料等。

3. Fuselage -- the main part that connects all parts of the model into a whole is called fuselage. At the same time, the fuselage can be loaded with necessary control parts, equipment and fuel.

4、起落架———供模型飛機起飛、著陸和停放的裝置。 前部一個起落架，后面兩面三個起落架叫前三點式；前部兩面三個起落架，后面一個起落架叫后三點式。

4. Landing gear -- a device for model aircraft to take off, land and park. One front landing gear and three rear landing gears are called front three-point landing gear; three front landing gears and three rear landing gears are called rear three-point landing gear.

5、發(fā)動機———它是模型飛機產(chǎn)生飛行動力的裝置。模 型飛機常用的動裝置有：橡筋束、活塞式發(fā)動機、噴氣式發(fā)動機、電動機。

5. Engine - it is the device of model aircraft to generate flight power. The commonly used dynamic devices of model aircraft are: rubber band, piston engine, jet engine and motor.
