模型飛機(jī)一般與載人的飛機(jī)一樣，主要由機(jī)翼、尾翼、機(jī) 身、起落架和發(fā)動(dòng)機(jī)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(jī)翼———是模型飛機(jī)在飛行時(shí)產(chǎn)生升力的裝置，并 能保持模型飛機(jī)飛行時(shí)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(jī)飛行時(shí)的俯仰安定，垂直尾翼保持模型飛機(jī)飛行時(shí)的方向安定。水平尾翼上的升降舵能控制模型飛機(jī)的升 降，垂直尾翼上的方向舵可控制模型飛機(jī)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(jī)身———將模型的各部分聯(lián)結(jié)成一個(gè)整體的主干部 分叫機(jī)身。同時(shí)機(jī)身內(nèi)可以裝載必要的控制機(jī)件，設(shè)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(jī)起飛、著陸和停放的裝置。 前部一個(gè)起落架，后面兩面三個(gè)起落架叫前三點(diǎn)式；前部?jī)擅嫒齻€(gè)起落架，后面一個(gè)起落架叫后三點(diǎn)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(dòng)機(jī)———它是模型飛機(jī)產(chǎn)生飛行動(dòng)力的裝置。模 型飛機(jī)常用的動(dòng)裝置有：橡筋束、活塞式發(fā)動(dòng)機(jī)、噴氣式發(fā)動(dòng)機(jī)、電動(dòng)機(jī)。

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.
