什么是航空模型呢？凡是不能载人、符合一定技术要求、重于空气的飞行器都可称为航空模型。下面
大型航空模型制作厂家来讲讲航空模型的一般知识。
What is an aviation model? All aircrafts that cannot carry people, meet certain technical requirements and are heavier than air can be called aviation models. Next, large-scale aviation model manufacturers will talk about the general knowledge of aviation models.
模型飞机的组成
Composition of model aircraft
航空模型与真飞机一样，主要由机翼、尾翼、起落架、机身和发动机五大部分组成。
Like the real aircraft, the aviation model is mainly composed of five parts: wings, tail fins, landing gear, fuselage and engine.
模型飞机的组成
Composition of model aircraft
机翼：是模型在飞行时产生升力的装置，并能保持模型的横侧安定。
Wing: It is a device that generates lift when the model is flying, and can keep the lateral stability of the model.
尾翼：包括水平尾翼和垂直尾翼两部分。水平尾翼保持模型飞行时的俯仰安定，垂直尾翼保持方向安定。水平尾翼的升降舵能控制模型的升降，垂直尾翼的方向舵能控制模型的飞行方向。
Tail wing: including horizontal tail wing and vertical tail wing. The horizontal tail keeps the pitch stability of the model in flight, and the vertical tail keeps the direction stability. The elevator of the horizontal tail can control the elevation of the model, and the rudder of the vertical tail can control the flight direction of the model.
起落架：供起飞、降落及停放用。
Landing gear: for takeoff, landing and parking.
机身：主要作用是将模型各个部分组成一个整体，同时可以装载必要的控制机件、设备和燃料等。
Fuselage: It is mainly used to integrate all parts of the model and load necessary control parts, equipment and fuel.
发动机：它是模型飞机飞行的动力装置。
Engine: It is the power unit for model airplane flight.
前缘：翼型的很前端。
Leading edge: The very front of an airfoil.
后缘：翼型的很后端。
Trailing edge: The very rear end of an airfoil.
翼展：机翼（尾翼）左右翼尖间的直线距离。
Wing span: the linear distance between the left and right wingtips of the wing (tail).
翼弦：机翼或尾翼的前后缘之间的距离。
Chord: The distance between the leading and trailing edges of an airfoil or tail.
机身长：模型飞机很前端到很末端的直线距离。
Body length: the linear distance from the very front end to the very end of the model aircraft.
：模型各部分重力的合力点。
Center of gravity: the resultant point of gravity of all parts of the model.
上反角：机翼前缘线与模型横轴线之间的夹角。
Top dihedral angle: the angle between the leading edge line of the wing and the transverse axis of the model.
机翼安装角：机翼翼弦与机身纵轴线之间的夹角。
Wing installation angle: the angle between the wing chord and the longitudinal axis of the fuselage.
机翼迎角：飞行中机翼与迎面留过的气流之间的夹角。
Wing angle of attack: The angle between the wing and the airflow left on the face during flight.
翼载荷：单位升力面积所承受的飞行重量。
Wing load: flight weight per unit lift area.
总升力面积：是模型飞机处于水平飞行状态时，机翼的总面积以及水平和倾斜安放的尾翼面积，在水平面上的正投影面积之和。
Total lift area: refers to the sum of the total area of the wing and the area of the horizontal and inclined tail wings on the horizontal plane when the model aircraft is in horizontal flight.
