型飞机一般与载人的飞机一样，主要由机翼尾翼机身起落架和发动机五部分组成。
Like manned aircraft, type a aircraft is mainly composed of five parts: wing, tail, fuselage, landing gear and engine.
机翼———是模型飞机在飞行时产生升力的装置，并能保持模型飞机飞行时的横侧安定。
Wing is a device that generates lift during flight of model aircraft and can maintain the lateral stability of model aircraft during flight.
尾翼———包括水平尾翼和垂直尾翼两部分。水平尾翼可保持模型飞机飞行时的俯仰安定，垂直尾翼保持模型飞机飞行时的方向安定。水平尾翼上的升降舵能控制模型飞机的升降，垂直尾翼上的方向舵可控制模型飞机的飞行方向。
Tail - including horizontal tail and vertical tail. The horizontal tail can maintain the pitching stability of the model aircraft, and 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.
机身———将模型的各部分联结成一个整体的主干部分叫机身。同时机身内可以装载必要的控制机件，设备和燃料等。
Fuselage - the main part that connects all parts of the model into a whole is called the fuselage. At the same time, the fuselage can be loaded with necessary control parts, equipment and fuel.
起落架———供模型飞机起飞着陆和停放的装置。前部一个起落架，后面两面三个起落架叫前三点式；前部两面三个起落架，后面一个起落架叫后三点式
Landing gear - a device for taking off, landing and parking of model aircraft. One landing gear at the front and three landing gears at the back are called the front three-point type; There are three landing gears on both sides of the front, and the rear landing gear is called the rear three-point type.
飞机发明之前，航空模型具有强烈的探索性质，在飞机发明之后，航空模型仍然是研究航空科学的必要工具。每一种新飞机的试制，都要先在风洞里用模型进行试验，甚连航天飞机这样的航空器，也要经过模型试验阶段，取得必要的数据，才能获得成功。
Before the invention of aircraft, aviation model had a strong exploratory nature. After the invention of aircraft, aviation model is still a necessary tool to study aviation science. The trial production of each new aircraft must first be tested with a model in the wind tunnel. Even an advanced aircraft such as the space shuttle must go through the model test stage and obtain the necessary data before it can succeed.
（2）航空模型是很有实用价值的器具。我国汉代就有用风筝测量距离和传递信息的。随着航空模型的发展，特别是无线电遥控模型飞机的日臻完善，航空模型的用途越来越广泛。
(2) Aviation model is a very practical instrument. In the Han Dynasty, kites were used to measure distance and transmit information. With the development of aviation model, especially the improvement of radio remote control model aircraft, aviation model is used more and more widely.
例如，可以利用无线电遥控模型飞机作为部队和民兵对空射击训练的靶机。在训练的时候，通过无线电遥控设备控制航模靶机完成直线飞行、转弯、上升、俯冲等飞行动作，甚在靶机上完成空投降落伞、发射模型火箭、投放炸弹、施放拖靶等特技动作。在实弹射击时候，可以在航模靶机尾部几十米远处拖拽一个彩色靶袋，以靶袋作为目标，避免击毁靶机。
又如，在无线电遥控模型飞机上装上摄影机，就可以对地面进行航空摄影，拍摄一些人们不容易接近的野生动植物，甚可以拍摄一些危险性很大的惊险镜头或战斗场面等。
For example, radio controlled model aircraft can be used as target aircraft for air shooting training of troops and militias. During training, the aircraft model target is controlled by radio remote control equipment to complete flight actions such as straight-line flight, turning, rising and diving, and even perform stunts such as parachute dropping, model rocket launching, bomb dropping and target dropping on the target. During live firing, you can drag a color target bag tens of meters away from the tail of the model aircraft target, and take the target bag as the target to avoid damaging the target aircraft
< p > for another example, if a camera is installed on a radio remote control model aircraft, it can take aerial photography on the ground, shoot some wild animals and plants that are not easy for people to approach, and even shoot some dangerous thrilling scenes or battle scenes.
另外，可以利用航模飞机携带农药灭虫，利用航模飞机拖一根尼龙线从一个山头到另一个山头，然后换成钢索，进行高山架线。还可以利用航模飞机飞入云层，施放催化剂，进行人工降雨，等等。
In addition, the model aircraft can be used to carry pesticides to kill insects, and the model aircraft can be used to drag a nylon wire from one mountain to another, and then replace it with a steel cable for high mountain stringing. Model aircraft can also be used to fly into the clouds, release catalysts, carry out artificial rainfall, and so on.
（3）航空模型是普及航空知识的玩具。
(3) Aviation model is a toy to popularize aviation knowledge.
航空模型活动在普及航空知识、培养航空科技人才方面所起的作用是很大的，许多的航空学家，小时候都非常喜爱航空模型。美国的莱特兄弟小时候就爱玩飞螺旋（竹蜻蜓），从而产生对航空事业的浓厚兴趣。美国登月飞船阿波罗11号船长阿姆斯特朗，小时候也酷爱航空模型，他在家里的地下室安装了一个风洞，用来试验自己制作的模型飞机，这无疑对他成为世界上个踏上月球的人有着巨大的影响。我国也有许多的飞机设计师、火箭设计师、飞行员等，小时候就是航模爱好者。
Aviation model activities play a great role in popularizing aviation knowledge and cultivating aviation scientific and technological talents. Many famous aviation scientists loved aviation models very much when they were young. The Wright brothers in the United States loved to play with the flying spiral (bamboo dragonfly) when they were young, resulting in a strong interest in aviation. Armstrong, captain of Apollo 11, an American lunar spacecraft, also loved aerial models when he was a child. He installed a wind tunnel in the basement of his home to test his model aircraft, which undoubtedly had a great impact on him to become the first person to set foot on the moon in the world. There are also many famous aircraft designers, rocket designers and pilots in China. They were aircraft model lovers when they were young.
