Origami Loop Airplane
In a discussion of aerial maneuvers, one cannot do without mentioning the loop, also known as the dead loop or Nerestov loop, named after the pilot who was the first to bring complex aerobatics to life. It is worth noting that the issue of who took leadership in the implementation of the deadly act still causes some controversy on the world stage. Thus, a whole galaxy of European countries elevates to the pedestal of championship A. Pegu, who was somewhat famous in those years for his celestial stunts and performed a similar figure in the same period of time as the Russian military man.
In the early years of aviation, the maneuver was considered exclusively theoretical as the aircraft models existing at that time could not cope with the load, and an attempt to implement such maneuver could only lead to the untimely death of the pilot.
The miniature prototype, the instructions for making of which can be found in this article, is able to give a graceful and energetic performance, performing a feat that in the past was considered only a string of impossible calculations. To make the entire structure, you only need paper and a little free time.
Expand and align the upper right corner with the central axis. Pay attention to the bottom corner (colon). It should be bent in half.
As a finishing touch, secure the back of the plane body with a small piece of tape, stapler, or glue. You can also adjust the diameter of the air loop by adjusting the angle of the valves.
