1、在航联制定的竞赛规则里明确规定“航空模型是一种重于空气的，有尺寸限制的带有或不带有发动机的，不能载人的航空器，就叫航空模型。
1. In the competition rules formulated by the Aviation Federation, it is clearly stated that "an aviation model is an aircraft that is heavier than air, has dimensional limitations, and cannot carry people, with or without an engine. It is called an aviation model.".
2、一般认为不能飞行的，以某种飞机的实际尺寸按一定比例制作的模型叫飞机模型。
2. It is generally believed that a model that cannot fly and is made to a certain scale based on the actual size of a certain aircraft is called an aircraft model.
3、一般称能在空中飞行的模型为模型飞机，叫航空模型。
3. Generally speaking, a model airplane that can fly in the air is called an aviation model.
4、模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。
4. Model aircraft, like manned aircraft, are mainly composed of five parts: wings, tail wings, fuselage, landing gear, and engine.
5、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。
5. Wing - A device that generates lift during flight of a model aircraft and can maintain lateral stability during flight of the model aircraft.
6、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。
6. The tail consists of two parts: a horizontal tail and a vertical tail. The horizontal tail can maintain the pitching stability of the model aircraft during flight, while the vertical tail can maintain the directional stability of the model aircraft during flight.
7、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
7. The main part that connects the various parts of the model into a whole is called the fuselage. At the same time, the fuselage can be loaded with necessary control components, equipment, fuel, etc

8。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，后面两个起落架叫前三点式
8。 Landing gear, a device for takeoff, landing, and parking of model aircraft. The front one landing gear and the rear two landing gears are called the front three point type
