1. Selection of materials: Any paper can be used to make Kongming lanterns, but it is best to choose materials that are denser, lighter, and less likely to catch fire. For example: translucent paper.
2. Design concept (draw a rough three-dimensional design diagram): The design concept must take into account
1. The position of the center of gravity of the sphere: try to avoid the design of the center of gravity deviating from the vertical center line, and do not make it in the During the lift-off process, the fire source burned the sphere.
2 Appearance, aesthetics, and surface processing: If the appearance design is asymmetrical, attention must be paid to the location of the fire source and center of gravity.
3. The weight of the sphere and the size of the fire source: The weight of the sphere is related to the lift, and the size of the lift determines the temperature of the air heated by the fire source and the size of the sphere. It is not suitable if the ball is too heavy and the fire source is too small.
3. Manufacturing process:
1. Calculate the volume of the lamp body and the dimensions of the split expansion
2 Use these expansion dimensions to cut the template from thick cardboard.
3 Use the template to cut the skin.
4 Bonding:
(1) There are two bonding methods:
(a) Overlap bonding method: After bonding, the bonded area will protrude from the surface of the ball. .
(b) After gluing, the bonding point should be flat against the spherical surface.
(2) Gluing steps:
(a) First, take two pieces as a unit and glue them together.
(b) Repeat the gluing step of (a) until the shape is completed.
5. Install the lamp source base: use thin iron wire or thick cardboard to make the base and stick it to the bottom of the lamp body, and use aluminum foil or a fuel barrel made of lighter aluminum cans to install on the base.
6. Test its stability: Use a hair dryer to blow up the lamp body, test its stability, and check whether there are any holes.
7. Paint and color.
4. Lift-off procedures:
The production method of the Kongming Lantern is very simple, but the lift-off process is greatly affected by the site and weather. When the wind is strong, it is easy to blow the lamp body sideways and burn the lamp body. When it rains, the lamp body is easy to get wet and cannot be released, so it is best to use it when there is no wind.
1. Open the lamp body first, and tie control wires around the sides and bottom.
2. Fill the fuel.
3. After ignition, press the air inlet as low as possible to reduce the loss of hot gas, but it should not be too low to avoid insufficient oxygen and flameout. At the same time, the surrounding control lines must be straightened.
4. After heating until the hot gas temperature in the lamp body is sufficient, slowly loosen the surrounding control wires to maintain the stable rise of the lamp body, and the control wire at the bottom must control the speed and height of the lamp body's rise.
5. After the sphere is lifted into the air, its height and direction can be controlled online, or it can be allowed to float freely. At this point, the sphere is lifted into the air.
