Aerodynamics made visible is always so cool to see. I'm glad this popped up in my recommended.

Please how far back from the leading edge were these VG installed? 5%? 8%???

Loved this video. Loved seeing the tell trails of the when laminar flow detaches. What sort of black magic are VGs?!

This video is awesome. Great work. Surprised all airplanes don't have these installed.

Great video

Excellent experiment ❤❤❤

Wird hier noch mitgelesen bzw kommentiert? Kann ich mir dir Vortex Teile auch selbst an die Fläche kleben? Ja, mir Jd bewusst das diese an bestimmte Positionen muss, hätte eine FK14 mit Vortex fürs aus messen für meine Maschine. LG

Verrückt, was nicht alles möglich ist.. 😛

Watching in April, 2023 for a class in aerodynamics. Thank you!

Fantastic, Thanks!

What was the actual landing speed?

Who else here after the Nepal plane crash, which is suspected due to the stall.😔

Great video. Does the wing have any washout? I'd expect to see this stall pattern (even without VG's) if it does.

Классно

At 2:34 you can see the more dramatic effect is the lateral movement, not the boundary layer backdraft forcing the strings up from the wing. The vortex generators aren't working as described.

Fantastic video! Thank you for taking the time and also sharing the video! VG clearly make a significant difference to stall speeds at different configs. The transcript is pretty hilarious though - I don't think the researcher actually says "and takes a sexy" at 12:11 🤣

This is the best video I've seen to date on this topic

I now think I know what I’m going to create and stick on my motorcycle’s fairings today. 😁

Why were they put on the tail? What were the results? Was there a benefit? The Wheeler has issues with tail effectiveness at high AOA and side slip. The speeds quoted could be misleading. You could have attached flow on part of the wing but the airplane could be descending I.e. at 0.9g instead of 1g. So the speeds, if you are using them to determine your operating speeds you should correct them by dividing them by the sq root of the vertical acceleration. This is a requirement for defining reference stall speeds on big airplanes. You can’t really claim a super low stall speed if the machine is falling out of the sky and you can’t arrest the sink.

Very interesting experiment! Seems like the ailerons work well past stall angle of attack of the wing. Reminds me of the zigzag tapes we put on som gliders. Low speed handling and induced drag usually improves, at high speed drag can increase but not by much. But it seems to depend on the airfoil shape. If I remember correctly the chordwise placement of turbulator tapes is also rather is critical.

Do anyone come up with the idea of retractable VGs? They could be retracted during the cruise and stick out during take off and landings.

My question is what were the level cruise speeds differentials with VG and without VG. Was it a large difference between the two. My research has found that it about a 1 to 2 kts difference in level cruise. As with Aviation, there's always a give and take scenario.

Looking at installing VG on my upcoming plane and want to ensure that I fully understand the need/safety implications/lower stall speeds/lower takeoff and Landing speeds that VG provides.

i hope one day they will make movable vgs as a standards on all planes like they have flaps

What happens if you get ice on them, as ice tends to form first on anything sticking up.

I'd like to see this on motorcycle windscreens to see if it can reduce helmet buffering while still using a smaller screen.

Guten Abend Herr Strausak / bei Interesse hätte ich Ihnen den link über 7 video's genau zu diesem Thema zu einer einzelnen Lancair in den USA // MFG

It helped me study

Amazing Video thanks for sharing

‎

Do they cause more drag at higher speeds? More fuel consumption? How much?

Thanks, awesome video!

These arent pilots. These are scientists with a huge pair of balls.

We added a VG kit to our stock standard 160hp Cessna 172N model a few years back and it changed the whole aeroplane. The first Cessna helicopter! The very low speed handling and very slow speed stall characteristics were there to see in the very first flight. Quite amazing really. I wouldn't want to go back to it's previous life not having VG's knowing now what VG's have done to it. In some configurations it seems almost impossible to stall..the ASI reads as low it can go on the dial. You don't even notice any change in IAS. It's only a 100 knot 172 afterall. So that's Yes Yes Yes Yes for VG's..

Great visuals!!

I would advise caution in doing this on half a wing as your changing the loading characteristics along the length of the airfoil.

All planes need VG, they should be standard.

With the outer VGs Ropes on the inside: OMG HELL WE ARE STALLING AHHHH MAYDAY MAYDAY Ropes on the outside: Crazy niggas what they doin over der

I see, that they delay the stall but then when the stall does happen it is quicker and more violent. They would also effect fuel economy at the cruise. There's a reason that small plane manufacturers don't use them and I suspect this is why.Many thanks to the poster for doing this video, well done.

Those vortex generators were supplied by stolspeed.com

ОХУИТЕЛЬНО!!!! :))) 1. Видео как сохнет краска 2. Как бродит квасное сусло + 3. Как дёргаются ниточки на крыле Лайк!!

With those vortex's you can make the tractor fly. Cheibe guet!

Those poor worms.

52 knots, elevator im Aschlag 😂

Cooli sach! :D Echt spannend das so Visuell chönne z gseh.

Such an instructive video. Thanks for your labor. Well done!

Back when I was a CFI, one day I covered the wing of our trainer aircraft with such yarn strips and flew it all day like that, showing student pilots the visual effect of stalling. They were all delighted to see first-hand something they had only studied in textbooks. ...I take it those VGs are not certified for general aviation aircraft? How does one go about installing them? Will the airplane not be illegal with such a radical aerodynamic modification, however beneficial it might be? Would the airplane need to be re-registered as "experimental"?

Alguém me explica?

stall?? no way.

Unreal. 15 knot change.
