'Pteromys' that transforms dragons and Dasypodidae into 'flying' paper planes based on aerodynamics is too great
Paper airplanes, which can be made simply by folding paper, are one of the typical play tools for children, but everyone should have the experience of 'it is difficult to make an airplane that flies well ...'.

The mechanism of Pteromys is explained in the following movie.

Pteromys: Paper plane model optimized for interactive design and free-form surface / free flight.
Even if you make your own paper airplane, it is difficult to fly it well.
The Pteromys system will realize a free-design flightable paper airplane. The following is an Armadillo model paper airplane with a design that makes you wonder, 'Is it really flying?'
If you throw it by hand, it will fly.
As a method to realize this system, we first created paper airplane samples of all shapes.
The flight trajectory of the sample is recorded with a video camera and converted into data.
Furthermore, by combining with the simulation data of the flight trajectory of the sample, the shape and lift of the wing were learned softly, and it became possible to generate an actual physical model.
The paper airplane design software 'Pteromys' was created in this way.
The simulated flight trajectory is displayed at the bottom of the screen.
If you change the shape of the wing with the mouse, you can see that the flight trajectory simulator is fluctuating.
All of the calculated flight trajectories draw unfavorable lines that crash immediately ...
If you check 'Make It Fly', the position of the wings will be optimized automatically, and the flight distance will be extended.
Furthermore, if you change the position of the wing, there is a function that automatically adjusts the position of the tail wing, and if you move the center of gravity or the position of the wing with the mouse, the overall balance is automatically optimized in real time. With such a system using machine learning, even inexperienced people can easily make flying airplanes.
The airplane model calculated by the software is cut out with a laser cutter, and it is completed simply by fitting it according to the cut.
As a result, the completed free-design paper airplane looks like this.
Even with such a dragon model ...
Flying without problems due to the aerodynamic design.
Even an airplane with a rather unusual shape ...
I was flying as simulated.
As a material, 1 mm acrylic sheet can be used in addition to paper. The cost is that any paper plane can be made for less than $ 1 (about 100 yen).
