Wingsuit Aerodynamics: Angle of Attack (Part 1)

[@xymoth_]

I never thought I'd be watching a presentation of my own accord but here I am lol

[@charlescrispi2730]

Is there a possibility that producing dimples on the helmet (similar to a golf ball) could delay flow separation and be especially helpful in those High AoA situations?

[@mingwu10able]

Fantastic video and great lecture! Learned so much about Wingsuit, which seems to apply to airplane as well. At around 10:36, the AOA = 65 not 75, a good test to see whether we, the students, are paying attention (to the math) or sleeping in the class :)

[@kerryemmerson8954]

AOA had some thing to do with lift and drag yes. If you are familiar with the humpback whale and the bumps that cover their leading edges, you might know that this enables stuck a huge animal to perform such right turns in the way they feed. I built a sailboat and epoxied lumps over the keel and forefoot. There is an outfit called whales power who work with this and Amnesiacs Cup boats use the bumps on the foils. Less drag. More lift. It works . Something different to think about.

[@billtruttschel]

Fantastic visual diagrams.

[@eniggma9353]

Thank you soo much, that was very informative.

[@mozvidz]

This is a good video, but I was unable to get an answer to a query in my mind. Which is, at what AOA does one need to be flying to hit the highest speed? Case in point, Fraser Corsan who still holds the World Record for highest speed did not necessarily fly at 0° to have the least minimal drag, so what was his AOA?

[@TheAndrewmcnelis]

Great vid.

[@manifestGrandManifestations]

Thank you bro much love. This is my dream before I move on to the next dimension. There should be skateboard wingsuit base jumps. Did I mention I want to wingsuit around the world in one flight. I Wana fly with wood

[@pcbondart]

I have as thought . . . to slow down wing suit flight, would it make sense to have a second wing above the flyer, similar to a rectangular chute, but much smaller? Sort of a biplane concept . . . obviously this makes things more complicated, how does the main work with this, etc.,

[@leefithian3704]

Working on it

[@okanergene363]

Excelent presentation

[@jubaierarnob5046]

Okan Ergene Lift vector is the green one in the video, perpendicular to the relative airflow.

[@ThorstenInJapan]

Thank you very much for that awesome video. I really like your professional and well defined approach to that topic. Is there any chance you publish the slides? I think this is a very good topic for bad weather days in my first flight courses.

[@manifestGrandManifestations]

Oh to the yea

[@mohammadsujon8048]

Please make more video about wingshut

[@KairHatchet]

Flying will come when you find the right weather, and the right conditions, both environmentally, and spiritually, and physically, and mentally.

[@micheleskydive]

Eccellente spiegazione.

[@error.418]

Would be curious to learn how you use your control surfaces to change your angle of attack. How does a wingsuit pilot affect their angle of attack?

[@rolandbruegger4482]

With the arm wings. Taking more of the arm wings in or back makes the flight steeper, reducing the angle of attack. Dihedral wing position. Vs Neutral or Anhedral arm wing position, which increases the angle of attack. Link: en.wikipedia.org/wiki/Dihedral_(aeronautics)#Anhedral

[@cosmicsurfer736]

Thak you for sharing.

[@SohailAhmedBaig]

wow

[@circa326]

guys its very simple... this is a classic case of flux using reynolds transport theorem.. Like cmon skydivers havent you taken fluid mechanics before?

[@alfiospuson7165]

no im not an intelligent person what do you mean explain

[@turkeeg7644]

I'm watching in case I'm recruited by the NSA for a secret mission and have to escape in the Alps.

[@KairHatchet]

I don't want to fly, I want to easily survive dropping off a building. I want a wing suit, that looks like Angle Wings, Fucked Owl Wings, that would also act as a Shelter, and Coat.

[@KairHatchet]

Three Parachutes is good enough to survive even if all three fail. What happens when I jump out holding a flag that's FUUUUCKKKIIINNNGGGGGG MASSIIIVVVEEE? Or a Mile long piece of 3 foot wide fabric? Does it really have to be a parachute? can we make fabric, Absorb wind? Or even, Repel wind? Or in other words, Increase or decrese the resistance of wind with electricity? So I can change the viscosity of wind? Make it harder or easier to flow through? Or even absorb it as a source of power? The better the tech the more efficient the tech, the more a gust of wind, will be absorbed into you, heating you, instead of Cooling you to much Or Cooling you, instead of heating you to much MmM? Or how about, creating drips of water in a bottle?

[@KairHatchet]

What if I spiral my speed? Then land? with body armour lmfao Which would just be like, Kevlar layers

[@KairHatchet]

Why aren't we using real wing feathers? Birds lose them all the time? Owl wings are designed for near silent flight and I want a suit that can just get me down to like... 120 kmh 90 would be nice 60 would be fantastic Even if I put a skid plate on my face, chest, and knees lmfaooo The small but light suit needs to be able to "bubble gum" When you want to land Watch birds attack pray from above with speed.

[@crevardos3976]

this shit doesn’t look safe

[@ehombane]

Safer then lying in bed. How many died using these toys? I heard of a few. How many died in a bed? Almost everybody ;)

[@MrAAAusername]

the term "angle of attack" should be taken out of all non power flight applications. Any real pilots would agree.

[@alfiospuson7165]

i do!
