Thank you so much !!! Very impressive and very educational !!! - I guess you guys already know that we wanna see the exit of the spiral when you get caught by your own downwash ... the stall and backfly ... the flow starting at the leading edge over the top of the airfoil ;-)

Super nice!! I think it would be nice to see the difference between a wing with winglet and one without. Another interesting test it would be to use 2 fumes on top of a selfie stick (like insta360) in front of the leading edge of the wing near the winglet Super video!!💪

If ever a heavily loaded Tandem Hang Glider is the foot launched aircraft that creates the most powerful wing tip vortices. It is good to know especially if you are following one near the ground. 🤗

Higher lift forces towards the wider surface of the wing compared to the tips, inequal but linear suction. Because of lower pressure above the wing towards the wider surface, it pulls air from wing tips area

It would be good idea to attach one more smoke at the center of the wing. It shows downwash. The most important thing for those flying behind, especially in thermals.

One thing that might be done more scientifically would be to measure the rotational speed of the vortex. When you compare the wings, you say that one of them produces a ``faster'' vortex, but this is something that is relatively easy to measure, no?

Yes, we could try an image correlation (like PIV) to get an idea of the velocity field. But it is easier to do this with particles than with smoke. This kind of experiment is more qualitative than quantitative.

forget wing tip vortices boys; EVERY one of those shroud lines creates WAY more drag than you think. Why not ditch the entire "inflatable -deflatable death wing concept" and just get yourselves some hang gliders? You WILL be MUCH SAFER; but you'll have to get a roof rack on your car.

at normal flight this is not that big.. its much bigger when you break the wing...
@Colombo38
3 жыл бұрын
There is the comparaison at 2:53, trim speed on the right vs breaks on left. Not much bigger, but spinning faster. The size is more linked to the aspect ratio and to the total lift produced by the wing (biger size, like a tandem, produce bigger vortices).

Salut. Ce sont des fumigènes d'airsoft. Tu peux les trouver en tapant fumigène eg18 dans google. On a jouté un allumage électronique (infla) pour simplifier la synchronisation mais pour ta manip ce n'est pas forcément nécessaire. Environ 1'30 d'utile.
