Annular Wing Test Flight 

The wing has a symmetric aerofoil profile on it. Flying at an angle of attack, it generates lift just like any other wing.

If only you could find a smaller area with more trees to fly it in.😀

I don’t always test annular wings, but when I do, I fly them into spiked bushes and make someone else retrieve them over and over and over and over....

My procrastinating is getting out of hand now.

You can tell the guy in the light blue shirt really wants a go and would probably be able to keep it in the air but the other guy will never let him touch the controls.

Do you test this once a year, like Annularly?

"There's a spider web there." Well, I guess we're never seeing that thing again.

so bushes and trees are its weak points. interesting.

“There’s a spider web there. ASSISTANT, retrieve my flying hole.”

The dude controlling it just looks like the kind of guy that doesn’t give up the sticks

The video was uploaded over 9 years ago, yet the comments are all from less than 9 days ago. Fascinating.

Ten years later: Still waiting on that Pitch and Yaw, Yall.

I see your problem there: the steering wheel is on the wrong side.

When all said and done, it’s ability has been pre-determined by the length of this test Area.

Imagine combining a lot of these together and making a flying dragon 🐉 it would look badass in a drone show

Congratulations, you invented the flying tambourine.

Me: Opens up RU-vid for the first time in the day. RU-vid: I know its 2021, why don't you watch this Annular Wing Test Flight from 2011

That wasn’t flying, that’s falling with style!

Imagine. When this was uploaded planes still had normal wings. Who knew a youtube video would have such an impact

Alternate title: two men throw a loop into bushes and shrubs for 2 minutes and 15 seconds

"Let's do test flight on a small area with tree's and building all around." "Yes"

“How to slam a circular thing into bushes”

Everybody gangsta till the hula hoop starts flying

When I was a kid, I had an Aerobie. This would've melted my brain in 1985.

Darling we are going on holiday on the latest plane design - Wow that’s so exciting where are we going ? A bush

When you think you are smarter than you are, and persist with a flawed theory. I give you, the annular wing.

Fascinating!

The beginning of something great!!

Keep going! I think you're getting closer to sustained stable flight if you can gain a higher altitude. An old pilot once said to me, "The closer you are to the ground, the more of a chance you have of hitting it."

Nice work! would be cool to see a few more of your vids. How do you intend to turn and control it?

Totally awesome man.

The force is strong with these 2

Now I have to go fold one up out of paper. I haven't made one for years, but they fly great.

“This is Mat, Mat is cool”

There's a lot of potential for very interesting things with this

Wow..... awesome!!👏

That looks like a HOLE lot of fun.

What if it's dropped from a dam creating magnus effect?

Some Kite flyers use circular kites, similar to this. They are called "Circoflex". Flex, because they are light and so, flexible. Their structure is just a carbon tube, and the lifting area is just a circular canvas attached to the carbon tube. The canvas is shaped by an adjustable lace at the rear part, a bit smaller than the canvas. So the air inside the loop is at higher presssure and maintains shape and some rigidity. The rope is attached to the center of a "star" of strings to the front end of the canvas. in fact, the "center" is lower than the geometrical center to ensure the stability, helped by some light weight fitted to one point of the low part of the canvas. They fly rather well, except if the wind is rather strong and turbulent.

How did you guys choose design parameters such as airfoil shape, diameter, etc? I'm looking to build an annular wing glider and am looking for design guidance.

Now I wan't to listen to Journey. Wheel in the sky keeps on turning...

I see RU-vid recommended this to y’all. Welcome.

This is actually a very impressive proof of concept.

That’s a very cool thing to see

No, not in this case. The aerofoil is symmetric so no angle of attack means no lift. That's why we had to launch it with some angle of attack to get it to fly properly.

In the voice of Capt. James T. Kirk: “Need. More. SPACE.”

Legends say that this was his prototype of the actually proposal ring he was working on!

Cool idea!

now I know where Ebony Maw got the idea for her Q-Ship

Come on let's go outside with this, we'll just wing it.

Sometimes they wait for the engines to get up to speed and then throw it and it works and other times they throw it and then try and get the engine up to speed which doesn’t happen and it hits the ground. What am I not getting about this process?

Ever since I saw those hyperspace rings for Jedi starfighters in the prequels, I've had the idea of a plane with a circular wing going around it like this

The sound flying saucers make.

let me know which planes these are fitted to so I can avoid like the plague!

Amazing!!!

Very nice innovation 👍

I don’t think Boeing and Airbus are going to enter a bidding war for the idea.

Hey mister tambourine pilot, fly a ring for me

I like the wide open space to test this out :D

Finally after 9 years.

I've got to be honest, theres a lot more "falling with style" going on.

ability to fly? -questionable ability to land? -please define landing ability to transport anything? -do stickers count? ability of engineer to think outside the box? -oh ya

awesome! 👍

I can certainly see the potential for an alternative to the more traditional flat wing design that has let us down so badly for in excess of 100 years. These guys are like aeronautical engineers less successful siblings. But I root for the underdogs, so keep up doing whatever that is. It’s only you crazy kids that move things forwards.

Put a star in the middle and that will be the perfect Captain America's shield🤔🤔😀

Now I'm no scientist, but maybe try this in a.....slightly bigger area?

_Legend has it they're still testing_

Amazing

Personally, I think he's just going in circles. Either that, or he's trying to reinvent flying in a roundabout way. I'm here all week.

Algorithm is finally blessing the video.

This would make an awesome ring toss game.

Cool! Have you seen this drone patent 6607162 ? The enclosed prop is what I like.

The airfoil is creating the same lift in all directions therefore gravity wins. Pretty cool though.

why did I just get recommended this

i just had an out of body experience. my old highschool had a small yard EXACTLY like that in the senior halls. but the camera turned and saw it was a full yard and not just a hall exterior. and im in florida!

A motorized Tubee.... Cool!

And today on: Where RU-vid has taken me 😂

Ummmm. You might want to consider another design...

Hell Yeah you got it!!

Two VERY SMART young men......................well done.

Flying means being able to adjust... this is gliding at best

If only we could all be as cool as Matt

It can clearly hover but can it be held onto a structure so that it can power some kind of aircraft

Yep, that's exactly how I always anticipate my airliner landings will be. 8)

Ooh, if I saw someone force their way through my nice hedge like that, you best run 😂

This is Thanos spaceship flying donut.. You're a visionary man!!

Symmetric airfoils generate the same amount of lift when reflected over their chord line. Which is what happens here as the whole thing rotates. An ordinary airfoil would start producing downforce when reflected, unless the angle of attack is very high (to the point of stall).

When an Australian warns you about a spider web, you listen

That is so cool tho! I hope they won their science fair or whatnot. 🥰

Very cool

The RC hobby has made insane advances in the past 9 years this video has been out, so this could work with the stuff we have now

I remember making a tiny version of this and launching it across the classroom it had a singular wing and didn’t spin though

This video is about to blow up. Let’s just hope we don’t find this annular ring on the luge/bobsled circuit

This is a sure way to make super serious tech. Especially for nasa.

Remember wide open spaces are not your friend when test flying new aircraft. Make sure u crash it at least 10 times to test durability before even turning the motors on. Anyway love the design!

What if you double the disc and make it spin in the opposite direction?

How do you alter prop speed for lift if the unit turns constantly...

That is sick you guys 🤘🏽 do you have a reverse just to see what it would do ? And seems like with the spin at a 45 degree works really well how about bumping it up to 55 degree spin throw might go far there

I would pay you if you would make me one of those. That is the nearest thing I’ve ever seen since sliced bread

I kept expecting it to just fly right through those trees like they weren't there. I guess there is a learning curve on this one.
