I've been working on the aerodynamics in A New Zero, one concept that is difficult to understand is lift. I've seen a few different explanations for what causes lift, but I wasn't really satisfied with them. So to better understand it I decided to make the simulated wind tunnel you can see in the video.
The wing shape is the simplest shape that creates lift. There's 4 sides, the two front facing sides are sloped to reduce drag and cancel each other out for force in the up and down direction. The back bottom face is parallel with the wind direction, so pressure is basically neutral. The back top face is what creates the lift, since it is sloped slightly away from the wind direction the pressure is less than the back bottom face and that creates an overall upward force.
The third clip demonstrates this effect, the fourth is a wing that creates no lift, and the fifth creates downward force. In the sixth clip you can see what happens when there's not enough pressure, eventually the air flows completely around the wing and only drag is created. The last two clips are a more rounded front face, and then a high angle of attack wing.
I'll be experimenting more with the fluid simulation, I'll post some more videos once I have some interesting things to show.
I also recently uploaded some of the music I've used for the videos, you can check it out here:
