This is a fascinating scaled-down study of ground-effect! We experienced this on a much larger scale in the KC-135 air refueling tanker. Whenever we had a very large receiver aircraft such as a B-52 or a C-5 Galaxy, our airplane would pitch nose-down slightly and airspeed would increase a few knots due to the reduction of induced drag from the other airplane’s wing. It had the opposite effect when the receiver aircraft departed, and at times was nearly violent if the receiver pilot wasn’t smooth with his exit. Thank you for this very cool experiment!!

[@kwerteh5049]

Peter, in many wind tunnels like the ones used to test aerodynamics of cars and stuff, the fans actually suck the air in instead of blowing it out. This gets rid of pretty much all turbulence. If you decide to retry this then maybe you can take this into consideration. :)

[@crackedemerald4930]

@Caleb P why's that? If he recreates the tunnel, you'd just need to put the plank of foam in front of the fan, and the plane in front of the plank.

[@whygym8813]

@Caleb P Exactly...

[@braeeee_]

@Caleb P you've got a point. The point of the air blowing onto the ramp is to generate lift. If the ramps sucked inwards it wouldn't work.

[@qwvpv]

@Caleb P if the fan was positioned behind the plane and the board to "suck air", i think the fan wouldn't be "pulling the plane" per say. The fan would be sucking the air all around it. The air would still be moving in the same direction as if it were being "pushed" or "blown". It would still hit the board and still generate lift. However, even if sucking the air is less turbulent than pushing it, as @KylePrupas said, sucking it into the board may still create too much turbulence for a steady "infinite flight".

[@awo1fman]

@Caleb P Wrong. The air flow is what matters, not the location of the fan. If the wind is blowing directly at a wall and you stand in front of the wall, the wind in the middle of the front of the wall is nearly as still as the air behind it. And wind is just as much air being sucked into a lower pressure area as it is air being forced from a higher pressure area.

[@mikehart5619]

When you are walking behind the glider, you constantly monitor its position and flight path and make adjustments. That is what keeps it flying. With the fan and the ramp, there is constant airflow which would keep it aloft but nothing to control it or bring it back on course when it starts to veer off.

To create true laminar flow, it's important to not direct the fans into the tubes, but rather at a 90° angle, to create a high pressure box behind the grid.

[@orac22]

The key is dynamic control. The clue is how you fly it when following it around with a board. You need a lift fan and two lateral fans controlled by a sensor (camera that senses plane position) and a (well, two) PD controller. It would more or less be like a magnetic ball levitator. If you can do it with your hands…

I think the turbulence came from the air not being completely laminar so i think you could use a funnel to organize the air particles in a straight line. Its the same principle that makes water streams perfectly clear. Smarter every day has a great video on this

[@jazzjohn2]

It seems like aircraft without any feedback control coming from somewhere cannot hover in the air indefinitely. The walk along glider has a control loop and that's why it can theoretically. The loop is the walker's eyes and brain with arm and leg muscles providing system input to keep it flying. You needed something to sense the position or movement of the glider, and a mechanism to adjust the controls as needed.

Seems one thing to conquer is a more rigid plane. As the plane flexes in the wind it develops different aerodynamics and thus changes how it reacts to the air. Keep as many things constant as possible.

Propellers:(made to provide airspeed and make a plane fly) Peter: Aight Ima use propellers to create drag...

[@StefanoBorini]

I suspect it's harder to keep it stable because the closer you get to the borders of your contraption, the slower the airflow becomes. This reduces the lift on the wing closer to the border and now it tends to drop that wing and lift the other, which now results in a turn that brings it even closer to the border. I think that the only way you can get this to work is with a teeny tiny plane for which the gradient of the flow is reduced. Alternatively, you can try to reduce the central airflow, so that it develops a natural tendency to be centered between two "spikes" of faster flows to the side. when it comes to thermaling, i can definitely tell you as a glider pilot that the thermal is by nature trying to push you out, for similar reasons as given above. The core of the thermal is fast raising air, and generally it's surrounded by colder air that descends. When you get a wing into the core, that wing lifts up, which makes you turn outside of it. It's hard work to get into strong thermals. Once you are in, however, it's relatively easy to stay in, as you are now part of the raising column.

Seems like an unstable equilibrium. When walking, you are making constant adjustments to speed and direction to keep it gliding, but with a ramp and fan, there’s no good way to make those quick adjustments. It’s like the difference between balancing a broom handle on your hand vs on the floor.

[@chelseahenderson7333]

2 Ideas. 1: Put the hand held cardboard on the end of a long rotating stick to replace the human element or 2: Think about the air flow you need as being more like a standing wave pool like surfers use on cruse ships. So the plain only gets a fast air boost when is getting low and can drift down when its too high. perhaps take some inspiration from a floor drying blower fan and get a flat laminar flow of air to flow only near the surface of your air ramp.
