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)飛機(jī)飛行時(shí)的橫側(cè)安定。

1. The wing is the device which can generate lift and keep the lateral stability of the 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. The tail consists of 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. The fuselage connects all parts of the model into a whole. The main part 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. The landing gear is 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)力裝置有：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. The engine is a device that generates flight power for a model aircraft. The commonly used power devices of model aircraft are: rubber band, piston engine, jet engine and motor.

航空模型技術(shù)常用術(shù)語(yǔ)

Common terms of aviation model technology

1、翼展機(jī)翼(尾翼)左右翼尖間的直線距離。(穿過(guò)機(jī)身部分也計(jì)算在內(nèi))。

1. The linear distance between the left and right wingtips of a wingspan wing (tail). (the part passing through the fuselage is also included).

2、機(jī)身全長(zhǎng)模型飛機(jī)前端到末端的直線距離。

2. The straight-line distance from the front end to the end of a full-length model aircraft.

3、模型飛機(jī)各部分重力的合力作用點(diǎn)稱為。

3. The point of resultant force of gravity of each part of the aircraft is called the center of gravity.

4、翼型機(jī)翼或尾翼的橫剖面形狀。

4. The cross section shape of an airfoil or tail.
