Course (Thematic)
1. What is the main role of passenger aircraft?
2. What are the main structures of an airliner?
3. If you had to design your idea of an airliner, how would you design?
1.Make a single piece of outline airliner
（1) Sketch the passenger plane in your mind.
(Tip: Draw a side view of the airliner)
（2) Use the mobile APP “Scanning Almighty King” to scan the painted train and import it into the laser software LasrMaker.
（3) Click “Picture – Crop” on the menu bar above the software to crop out the blank part.
（4) Click “Picture- Outline” to sketch out the outline.
（5)In the layer parameter area on the right of the software, select no output picture, box out the inner outline and delete it, leaving the outer outline, and finally select output picture.
（6) Double-click the layer parameter area on the right side of the software to set the parameters of the layer.
（7) After completing the above Settings, import it into the machine for processing, and the single piece of train will be made successfully!
2. Make a complete version of airliner
（1) Draw the wheels (called landing gear) of the passenger plane 3 and make several small wooden rings using the function of array replication. Finally draw a circle with a diameter of 3mm on the wheel (called landing gear) part of the passenger plane.
(The wheel size is a circle with a diameter of 13mm.)
（2) Use the “weld” function to design 2 plates for welding.
(Welding plate size is 20*15mm, welding card size is 10*3mm)
Draw the tail and main wings of the airliner
（3) Draw a 60*15mm rectangle for splicing the tail section of the fighter jet.
（4) Draw a 20 by 120mm rectangle and use the “Draw Bessel Curves and lines” feature to draw the wings of the fighter.
(In the process of drawing, first click the left mouse button to trace, and then drag to the appropriate place to trace, at this time do not immediately release the left mouse button, long press the left mouse button and drag, you can draw the arc, depict the appropriate arc to release the mouse, you can press the right mouse button to end the painting.)
（5) Copy and paste the wing for mirror processing, and use the “welding” function to weld the wing to the rectangle, the other side of the wing the same welding operation.
（6) Draw the corresponding bayonet and place it according to the position shown.
(The dimensions are①10*2.7 ②37 *2.7③15*2.7)
（7)Mirror the image to complete the final design.
After the design of all parts is completed, the design drawing is imported into the machine for processing, and the assembly is carried out after the machine processing is completed.
（8) Splice the welded plate on the cut fighter and use hot melt glue or white latex to glue it firmly.
（9) Attach the wheels to the front and rear of the aircraft using small sticks and wooden rings to act as landing gear for the aircraft.
（10) Use small sticks and small wooden rings to attach the wheels to the front and rear of the warplane.
(two for the rear wheel and one for the front wheel)
3. Machine processing
The design files saved in the above demonstration are respectively imported into the laser cutting machine for processing. Tip: remember to adjust the focal length before processing to avoid the situation of impenetrable cutting.
4. Works upgrade
Install remote control
（1) Use glue to attach the remote control receiver plate to the vertical tail of the passenger aircraft.
（2)Glue the two small motors on both sides of the main wing of the passenger plane and install the propeller on the rotating shaft of the two small motors. (The small motors on both sides should be symmetrical)
(Tip: After the installation is completed, manually turn the propeller to check whether it will touch the plane, if it touches the plane, a small board can be placed under the small motor.)
（3)Take out the battery box and the switch device, connect the black wire (negative electrode) on the battery box and the receiving board with electrical tape, and connect the red line (positive electrode) to the switch.
(Tip: the positions of the two red lines are connected)
（4) Connect the BL line (green line and white line) on the receiving board to the small motor on the right, install the battery, and press the right button on the remote control after opening the switch to check whether the small motor can rotate.
（5) Connect the BF line (blue line and yellow line) on the receiving board to the small motor on the left, also turn on the switch, press the left button on the remote control to test whether the small motor can rotate.
Installation notes:
1. The direction of rotation of the propellers on both sides should be opposite, that is, the rotation direction of the left propeller is clockwise, and the rotation direction of the right propeller is counterclockwise.
2. The B arc of the spiral blade leans inward (bends inward).
3. After installation, install the 18650 lithium battery and turn on the switch. Use the remote control to check whether the propeller can drive the aircraft forward.
If the aircraft can move forward, the following two situations will occur:
Press the upper button of the left and right keys of the remote control, and the plane moves forward (Normal).
Press the lower keys of the left and right keys of the remote control, and the plane is driving backward, then the wires of the small motor are removed, and the positions are exchanged to reconnect.
(Tip: The green and white wires are still connected to the right motor, and the blue and yellow wires are still connected to the left motor.)
If the propeller does not move the aircraft forward, the following installation problems occur:
1. Electrical wiring is incorrectly installed.
2. Propeller installation error, B arc outward.
3. The rotation of the propellers on both sides is not opposite, that is, the rotation in the same direction.
If the plane can travel forward normally, then the remote-controlled aircraft is done!

Fuselage, wing, tail (divided into vertical tail and horizontal tail), power plant, take-off and landing device, etc.
2.What is the function of each basic structure of an airliner, respectively?
Fuselage: for carrying people and things
Main wing: Generates lift, but can also house ammunition silos and fuel tanks inside the wings, and can store landing gear in flight. Tail wing: controls the lift and deflection of the aircraft, and ensures smooth take-off and landing.
Power unit: to ensure the normal operation of the aircraft engine
Take-off and landing device: to ensure the flexible movement of the aircraft on the ground, reduce the impact and turbulence of the aircraft landing, taxi brake deceleration.
