II. Appreciation
（出示各種戰(zhàn)斗機圖片），請學(xué)生從外觀造型上分析戰(zhàn)斗機的外形特點。特別是機翼的多少？以及駕駛室的位置？殲擊機，又名戰(zhàn)斗機，即用于在空中消滅敵機和其他飛航式空襲兵器的軍用飛機。
(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.
三、Analyze分析：

第二課時 –尾翼組裝
Lesson 2 – Tail Assembly
一、 目標:
I. Objectives:
1、了解戰(zhàn)斗機的主要職責，對戰(zhàn)斗機的功能性詳細介紹

2、結(jié)合實際組合尾翼的結(jié)構(gòu)，分辨出疊加拼裝的方向。
2. Combining with the actual structure of the tail combination, the direction of the stack assembly can be distinguished.
二、欣賞：
II. Appreciation
（看一段戰(zhàn)斗機演習的視頻），戰(zhàn)斗機的主要任務(wù)是與敵方殲擊機進行空戰(zhàn)，奪取空中優(yōu)勢(制空權(quán))。其次是攔截敵方轟炸機、強擊機和巡航導(dǎo)彈，還可攜帶一定數(shù)量的對地攻擊的武器，執(zhí)行對地的攻擊任務(wù)。
(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:
圖一：上尾翼的組合，觀察尾翼的結(jié)構(gòu)，及固定的位置方向
Figure 1: combination of upper tail, observing tail structure and fixed position and direction
圖二，三：疊加下尾翼和連接軸的上下關(guān)系，特別分清楚鉆石型鐵片的位置。
Figure 2, 3: distinguish upper-lower relationship between the lower tail and the connecting axis, especially the position of diamond shaped iron sheet.
圖四：將其尾翼部分與機身組合在一起，這里的機翼連接要求空與孔對齊
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、認知與管理
IV. Knowledge and Administration
1、認識尾翼的四孔三角形和三孔鉆石型鐵片。
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，操作盤，和戰(zhàn)斗機2號袋零件。

第三課時 –三點式起落架組裝
Lesson 3 Three-point Landing Gear Assembling
一、目標:
Objectives:
1、了解飛機起落架原理及其作用。
1. Understand the principle and function of aircraft landing gear.
2、認知不同形狀的墊片，了解起落架的組裝順序。
2. Recognize the different shapes of the gasket, and understand the assembly sequence of the landing gear.
二、欣賞：
II. Appreciation
（看一段戰(zhàn)斗機起飛時的視頻）飛機起落架就是飛機在地面停放、滑行、起飛著陸滑跑時用于支撐飛機重力，承受相應(yīng)載荷的裝置。主要作用1. 承受飛機在地面停放、滑行、起飛著陸滑跑時的重力; 2.承受、消耗和吸收飛機在著陸與地面運動時的撞擊和顛簸能量; 3. 滑跑與滑行時的制動; 4. 滑跑與滑行時操縱飛機。
(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：
