Michael, the data of twist of this model designed by Albion Bowers is all to be found at my website in the flying wing section. nestofdragons DOT net .
All the data about this wing can be found on my website. It has the same name as my channel here and ends on POINT NET. Go visit the flying wing section, the Horten pages. At right you will see a link to the DRAGONWING pages. In one of those pages in the link to the Excell-sheet with all the data.
Did you get inspired by the NASA Prandtl Wing ? Or pure Horten basics ? www.nasa.gov/centers/armstrong/news/FactSheets/FS-106-AFRC.html I would like to understand their philosophy better, to design wingtips. Wie is er van Antwerpen ?
Beautiful airplane! Did you ever have experienced dutch roll in this kind of configuration (bell shape lift distribution)? I´m working in a similar project and this phenomenon appears when flying at low speed! I'll be very grateful if you can give me some advice! Thanks!
In the first test we used a dihedral of 5°, just like the drawings of Reimar Horten showed. It had some severe adverse yaw. Crashed a few times. We reduced the dihedral to 2° and all became smooth. We only encountered adverse yaw when large deflections of the elevons were used. We no longer saw adverse yaw, but saw proverse yaw when flying with normal deflections. So ...some stops are needed for the elevons to prevent those large deflections to happen.
We find an error in the CAD files, the assembly design has an error that results in a dihedral angle of 4 degrees greater than it should be. As you said, that should be the reason of this non-desirable phenomenon! The dihedral has already fixed and we are going to try a new fly next week. Thanks in advance!!!
The knowledge about that dihedral problem came by pure chance. It was the only thing we could quickly alter during our first DragonWing tests. And ...our result was awesome. We totally lost the feeling that the glider wobbled around.
Hey! A friend and I are interested on making a project about the Prandtl wing on my university. I was wondering did you guys worked out the math for the change in geometric twist on each panel or how did you end up getting the bell shape distribution? Thanks
The wingdesign was done by Albion Bowers, while he was still NASA chef engineer. You can find him in FB. Also go see my website. Marko Stamenovic made a tool to design in BSLD. You can find it on the flying wing section. It is called FLYING WING DESIGNER. Very usefull!!
All data about my project. Airfoils, twist, building proto can be found on my website. Name of it is same as youtube channel but ends on dot net. Go see section about flying wings. DragonWing.
@@nestofdragons I am having trouble finding the section on DragonWing. I have looked at every possible section under 'Weird Airplanes', but still can not find it? Please help! Also, you have great curated sections on many unusual and historic craft, all in one place, very well done! Have you heard about the Norman Bel Geddes Airliner # 4? I think you might want to include it :)
The work on this project set a start for a project at NASA. It now is the kind of model they intend to be used on Mars. And ...a friend of my NASA-contact is building a full scale. It flew already. They intend to produce it as a hangglider. 2017 is going to be soooo cool for flying wing fans!!! :)
If it has a MOTOR then it is not a glider, otherwise anything with a motor than can glide, would be a glider. That includes an F4 on a 'bad' day. Designing, building, and flying with NO motor is TOTALLY different, and should be "Glider". Else, its a plane with good lift. And that's Cool....yet DIFFERENT. Power "off" is not the same as never designed for anything but silent LIFT.
There are MANY powered gliders. They are designed to get the glider up to altitude and not use the motor after. Any plane with a motor can glide, but can it thermal for hours like this can? No. Then it's not a glider. THIS IS a glider. You embarrass yourself with your statement.
For crying out loud, man! Just CHILL OUT! So it has a motor... That makes it a motorized glider... The motor is just a convenient substitute for a bungee cord, or a tow plane. It is quite obvious that this incredible thing soars nicely off power. Look at what's been accomplished, and stop whining over the definition of the word "glider"... Anyway... Nice work. I just hope no one loses it in the Sun. The thing is hard to see.
Wait, what school did you go, elementary school, first grade, what school? If this model is a glider, what makes you so sure that it is a glider? It has a motor, it is pushed by a motor into flight and it permanently uses a motor to stay airborne, right? Now, how is this a glider? I mean, what school did you go not to know what 'glider' is or means? Check the dictionaries before writing a bullshit title for this model doesn't glide or soar at all, therefore it doesn't fall into the glider category. Sorry about that. - Oxford Dictionary - Glider (aircraft) means... - glider - /ˈɡlʌɪdə/ noun 1. a light aircraft that is designed to fly without using an engine. Or... 2. A glider is a fixed-wing aircraft that is supported in flight by the dynamic reaction of the air against its lifting surfaces, and whose free flight does not depend on an engine. And you call your motorized model a glider? Yeah? Doh! Go back to school for Chrissake. It's just a motorized model Flying Wing.
Hello Mick, i do think you just broke a heart of a USA citizen. The guy who got this glider as a gift for his calculation work on this project never had any problem with me using the word "glider". He knows that this project can soar and soar. Great glider performance. But i guess you didn't watch the video long enough before you started commenting. Anyway ... the guy who owns the RC model now is a retired NASA chief engineer, Albion Bowers. So ... would you be so kind to ask him what school he did and why he never made a problem when i said glider to this model? Hope you still have a good day.
Hello Mick, i see you changed your text a bit. Ok, you have noticed wrong. It only uses power to get to heights, once there we cut off the power and let it soar. It can easily climb in thermals. It has a very good glide ratio. So ... in airplane terms, it has specifications which are too good to be a usual prop-airplane. I consider it as a motor-glider. The real project (the full scale) was intended to only be 100% glider. Take off would be by running of a hill like a hangglider. But a hangglider uses mostly weight shift. So ... is it a hangglider? I use controlsurfaces. What i try to say, Mick, is that this airplane would have been so unique that it belongs in a rather new category. It is a foot launchable ultralight sailplane. The RC model you saw here is its study project to test all kinds of elevons and test its stability. It was fun to do. We learned a loooooooot. The results influenced some guys at NASA. So, i am super proud about its existence.

This is a beautiful aircraft, I had the pleasure of working with Albion on this design this summer.
Jack Toth : Just found out for to reply in the new system. Man, i envy you for being able to talk the same airplane language as Albion Bowers. :)
Michael, the data of twist of this model designed by Albion Bowers is all to be found at my website in the flying wing section. nestofdragons DOT net .
I made a plank version of this idea from Dollar Tree Foam Board (similar but stiffer to Depron). Your website gave me great inspiration!
AAAALWAYS NICE TO HEAR. that is the reason of the existance of the site. Help others.
the endless glide of Horten's Spirit
Best regards , where find drawings for make one simmilar?

Wie is er van Antwerpen ?
In fact ... the wing was designed by Albion Bowers of the NASA Prandtl project. He made this design BEFORE his started working on the NASA Prandtl.
Nice project 👏🏾. So, are you have project of baioneta?
Fantastic Wing!

Amazing flight...congratulatios .
Brilliant! My attempt at this had tip stall problems, I think I didn't have enough taper on the elevons. What airfoil are you using?

Go to weird airplanes, Horten section, see the DragonWing link between the links at right top. Go see design by Albion Bowers. The Excell is there.
Where did you fly this? It's not loud is it?
We flew it in the Netherlands. There is also one in California. But i think it is only used for static display by a NASA engineer.
Cool Thanks,
Prop isn't balanced maybe.. bent shaft..
if i recall right the rear mount broke off. A wonder that the prop didn't tear the rear apart.
Wow! Ya, if that shaft isn't perfectly strait or that prop isn't balanced, that could easily be a catastrophic failure.
Way awesome project! On par with the Wright Brothers, I would say, as far as historic significance in aviation.

I see no need to use the exact meaning for glider. I am not into F4-stuff. To me, if it does not always fly motorized, it is also a glider.

en.wikipedia.org/wiki/Motor_glider
I'm gonna side with the pedant. Otherwise all powered planes shall henceforth be designated as "motorized gliders"
For crying out loud, man!
Just CHILL OUT!
So it has a motor...
That makes it a motorized glider...
