A movie that reproduces the physical phenomenon 'wake turbulence' that always occurs in aircraft on paper airplanes

Wake Turbulence From a Paper Airplane-YouTube
'Airplanes push or cut through the air, which inevitably creates a turbulence in the atmosphere called'Wake Turbulence',' Schrader said while flying a small light aircraft.
One of the phenomena that occurs as a by-product of this wake turbulence, but 'Wingtip Vortices (
At this time, the airflow is generated along the outer circumference of the wing, so the left and right wings form vortices in opposite directions. This is a phenomenon called wing tip vortex.
'Because the air is transparent, this phenomenon is almost always invisible, but it can be visible in certain weather conditions. In reality, wingtip vortices are a beautiful phenomenon.'
Below is a movie that actually captures the wing tip vortex. An image of the moment theAirbus A380 pierces a huge cloud, taken by Australian photographer Michael Marston. The clouds that the Airbus A380 passed through form a vortex against the background of the sky illuminated in red by the setting sun.

Mr. Schrader, who was playing with a wake turbulence and wing tip vortex in his room as usual one day, came up with the idea of 'creating wake turbulence on his own.'
'All planes fly with lift and produce wingtip vortices as a by-product, so I thought it would be possible to generate wingtip vortices on a very small scale with paper planes.'
The first step in the project to create a wing tip vortex with a smoker and a paper plane was to 'cool the smoke with ice.' It seems that the smoke that was not cold enough did not float well in the room.
Regarding lighting, in order to clearly capture the flow of smoke in the image, the strategy is to darken the room and illuminate the smoke with a light.
The next step is to 'fold a paper plane'. It looks better if you fly straight in front of the camera, so Schrader repeatedly tweaked the paper plane to fly as straight as possible.
The final step is to 'actually fly'. In a pitch-black room, he started the smoke machine in front of the light, flew a paper plane, and photographed the situation over and over again.
'It's really good!'
When I actually tried it, it was quite difficult to fly a paper plane so that I could see a whirlpool of smoke, Schrader said, 'I did it for hours.' The video with such hard work can be viewed from 3 minutes 26 seconds of the movie. Click the embed below to start playing from 3 minutes 26 seconds.

Immediately after the paper plane faded out, the smoke was distorted as if a large hole had opened ...
A vortex wing tip was created slightly below the space where the plane jumped.
The movie repeats the same trial multiple times, and it is captured that the vortex wing tip is formed each time.
There is also a scene where the vortex wing tip is formed so as to protrude from the smoke.
'Even a paper plane, which weighs very little, has the same physics as a 300,000-pound airliner and can generate the same aerodynamic phenomenon. It looks great and is beautiful. And I really like this phenomenon. '
According to Schrader, wake turbulence generated by large aircraft often causes accidents, and 'people who drive small light aircraft should refer to the following article.'
