II. Appreciation

（出示各种战斗机图片），请学生从外观造型上分析战斗机的外形特点。特别是机翼的多少？以及驾驶室的位置？歼击机，又名战斗机，即用于在空中消灭敌机和其他飞航式空袭兵器的军用飞机。

(Show pictures of all kinds of fighter aircrafts). Ask students to analyze the appearance and characteristics of the fighter aircrafts from the outlook and modeling. Especially, How many wings does it have? And where is the location of the cab? Fighters, also known as fighter aircraft, are military aircraft used to eliminate enemy aircraft and other aerial attack weapons in the air.

第二课时 –尾翼组装

Lesson 2 – Tail Assembly

一、      目标:

I. Objectives:

1、了解战斗机的主要职责，对战斗机的功能性详细介绍

1. Understand the main responsibilities of the fighter aircraft and give a detailed introduction to the functionality of the fighter aircraft

2、结合实际组合尾翼的结构，分辨出叠加拼装的方向。

2. Combining with the actual structure of the tail combination, the direction of the stack assembly can be distinguished.

二、欣赏：

II. Appreciation

（看一段战斗机演习的视频），战斗机的主要任务是与敌方歼击机进行空战，夺取空中优势(制空权)。其次是拦截敌方轰炸机、强击机和巡航导弹，还可携带一定数量的对地攻击的武器，执行对地的攻击任务。

(Watch a video of a fighter aircraft exercise). The main task of a fighter aircraft is to carry out air combat with enemy fighter aircrafts and seize air superiority (air control). The second is to intercept enemy bombers, fighter aircrafts and cruise missiles, and also carry a certain number of weapons against ground to carry out the task of attacking the ground.

三、分析：

Analysis:

图一：上尾翼的组合，观察尾翼的结构，及固定的位置方向

Figure 1: combination of upper tail, observing tail structure and fixed position and direction

图二，三：叠加下尾翼和连接轴的上下关系，特别分清楚钻石型铁片的位置。

Figure 2, 3: distinguish upper-lower relationship between the lower tail and the connecting axis, especially the position of diamond shaped iron sheet.

图四：将其尾翼部分与机身组合在一起，这里的机翼连接要求空与孔对齐

Figure 4: The tail is combined with the fuselage together, where the wing connection requires the hole to be well aligned with each other.

四、认知与管理

IV. Knowledge and Administration

1、认识尾翼的四孔三角形和三孔钻石型铁片。

Know the 4-hole triangle and 3-hole diamond iron sheet of the tail.

2、管理自己的工具箱，拿出工具，操作盘，和战斗机2号袋零件。

Manage your own toolbox, takes out tools, operation board, and No.2 bag parts of fighter aircraft.

3、检查零件种类与数量。

3. Check the type and quantity of parts.

五、拼装

第三课时 –三点式起落架组装

Lesson 3 Three-point Landing Gear Assembling

一、目标:

Objectives:

1、了解飞机起落架原理及其作用。

1. Understand the principle and function of aircraft landing gear.

2、认知不同形状的垫片，了解起落架的组装顺序。

2. Recognize the different shapes of the gasket, and understand the assembly sequence of the landing gear.

二、欣赏：

II. Appreciation

（看一段战斗机起飞时的视频）飞机起落架就是飞机在地面停放、滑行、起飞着陆滑跑时用于支撑飞机重力，承受相应载荷的装置。主要作用1. 承受飞机在地面停放、滑行、起飞着陆滑跑时的重力; 2.承受、消耗和吸收飞机在着陆与地面运动时的撞击和颠簸能量; 3. 滑跑与滑行时的制动; 4. 滑跑与滑行时操纵飞机。

(Watch a video of a fighter aircraft taking off) the landing gear is a device used to support the gravity of the aircraft and bear the corresponding load when the aircraft is parking, taxiing, taking off and landing. Main functions: 1. Bear the gravity when the aircraft is parking, taxiing, taking off and landing; 2. Bear, consume and absorb the collision and turbulence energy when the aircraft is landing on the ground; 3. For braking when the aircraft is in taxiing and skating; 4. To operate the aircraft when the aircraft is taxiing and skating.

三、分析：

Analysis:

图一：有序串联起落轮子的拼装，知道中间的小圆柱型是轮毂，旁边两个薄的黑色垫片是保护轮胎能正常转动。

Figure 1: Assemble landing wheels in series order, knowing that the small cylinder in the middle is the hub, and the two thin black gaskets beside are used to protect the normal rotation of the tire.

图二：起落轮子固定在2孔L型铁片的椭圆孔上，在固定紧轮子前，一定要保证轮子在椭圆孔的最下方。

Figure 2: the landing wheel is fixed on the elliptical hole of 2-hole L-shaped iron sheet. Before fixing the wheel tightly, make sure that the wheel is at the bottom of the elliptical hole.

图三：安装3个起落装置在飞机的前后左右位置。
