Device and principle of operation
So, the paper lantern consists of several structural elements:
- The supporting structure is represented in it by a wooden frame, which is made most often from bamboo.
- The lower part of the frame is attached to the burner by means of a thin wire. If we talk about the traditional burner, then it is made of cotton fabric, which is impregnated with wax. It can also be made of paper, which is impregnated with flammable liquids. Modern analogues have burners made of combustible polymers.
- Traditionally, the dome is made from rice paper. As a rule, it is impregnated with a special compound that prevents its ignition. The skeleton and dome of Chinese flying lanterns can be made in various shapes, starting from the ball and the cylinder, and ending with animal figures.
The principle of operation of such a flashlight is to heat the air with a burner to a temperature of about 120 degrees Celsius. Since the heated air has a lower mass, it also ensures that the flashlight is raised in colder air.
