Hi Alan,

I cannot answer Your Question, but I can tell You, that she's a real masterpiece. Everything looks very clean and well done.

Scale / Horten XIV building thread

« on: August 27, 2009, 14:16:55 PM »

No Alan,

none of them. We design the wings in "Nurflugel.exe" from Frank Ranis. This program is able to export the profiles to dxf-files. With those files I draw my ribbs. Every ribb is different from all the others bcause of the not linear washout and so on.

The whole thing is complicated for me to explain it in german, so please don't ask me for this in english :oops:

Scale / Horten XIV building thread

Hy friends,

the last days I started building the center sections. There will be two of them. Of course one built as scale as possible for me, have a look here:



and, because I have no slope and don't want to depend on a tow, an "experimental center-section".



This one will get a motor with a pusher-prop. So I can learn to fly this plane in my area, somebody from Argentina called it "German Pampa" :wink:

Scale / Horten XIV building thread

« on: August 26, 2009, 21:08:09 PM »

Hi out there,

as promised, I start a little picture thread about my newest Horten Nurflügel (flying-wing) project.

The Horten XIV (14) glider was designed by Reimar Horten in the beginning of 1945. His Idea was to build a clubglider based on the HIV high-performance wing. I made a little research about the real plane. There is omly a little sketch in the book "Nurflügel" (R. Horten/ P.F. Selinger) and some drawings of the center sektion at the Nurflügel-Archiv at Mr. Uden.

The Scale will be 1:4. This makes a span of 4 m with about 5 kg. The aerodynamic of the model is designed by Uwe H. and Andrès C. at www.ig-horten.de.

So here we are. First of all I made a drawing of the wing:




Afterwards I imported the profiles to CAD and made the drawings of the ribbs. Well, this is a longer story. Especially the unusual Center-section has it's geometric problems...

That's, how it looks on my computer:



After some weeks of CAD, it's time for the milling maschine to get busy.

Here is the result:

Wow,

that's a great Idea for boys over 50. But than some new eyeglasses would be cheaper I believe....

Well,

as Keith asked me, here are the pictures of my basement. It's warm there in the winter and cold in the summer. Perfect place to build modells of submarines, ships and flying wings.

This is the workbench room. Here I am building wings up to 5m span:



Another view with my lathe:




Here is the room beside, where is my hangar and harbour:



and a nice view on my CNC milling maschine:



It's not as clean as Keith's or Vincent's room, but cleaner than Fred's...

Hi Keith,

Yes, they can roll and loop. The Horten II was in the 1930's often used for aerobatic-demonstrations. My little Horten XII (You've seen it on the airfield, when we meat the first time) is also able to do it. I tried it when the plane was high in the air, because I am a bad pilot. But it works.

With my Probe1 I made loopings sucsessfull. But the problem with those "high aspect ratio" planes is, that they are often not strong enaugh.

If You are interested I could make a litle building-picture-thread of the newest IG-Horten-projekt. It will be the Horten XIV. This was a never flown Clubglider designed in beginning 1945 by Reimar Horten. I build it in plywood.

Well Allan,

I always felt, that modelling has to do with miniaturizing...... That's wrong I believe :wink:

Ok......

well, first of all, i would have to buy a camcorder... this Idea is rising my adrenalin level more than enaugh for the next weeks:lol:

But if You like, You could go to www.rcmovie.de and search (suchen) for Horten. There You'll find some nice videos of boomerangs incl. mine.

Hi,

please have a look here:

http://www.flyhard.ch/bauberichte/bauberichte.html

The page is written in german (what a beautifull language :mrgreen: ), but when You klick on the menues on the left side, You'll find some picture galleries of building big models.

These are 3 guys, who built only real big models. The building of the Austria begun in Summer 2008.

I do not really understand the reason to built so big. May be when my eyes are getting older, I need such big planes :lol:  For the next time I'll sta with my boomerangs

Slope Soaring / Retroplane... In Ireland !

« on: July 24, 2009, 07:01:18 AM »

Well Keith,

i can tell You, if You've made Your own drawings on the computer, if You've seen Your millingmaschine making the ribbs and frames and so on, and when You build on Your plane for months with plywood and glue,

then You will feel your heart beating very hard in Your cheast, You will be wet in all Your clothes and You need some rubber between Your knees to protect them whlie swingeing against each other :lol:

I can tell You, it doesn't look as spectacular as acro-flying at wind of 60km/h (what is it miles per hour? :wink: ), but it can be the best kick of adrenalin You ever get. :shock:

think about it.... :mrgreen:

Viele Grüße

Slope Soaring / Retroplane... In Ireland !

« on: July 23, 2009, 16:41:54 PM »

Hey Bill,

keep Your english. I am happy about everybody at Retroplane, who speaks a language I understand

Well, for me the driving distance is the same to Austria and to Cherbourg.... But I would prefer Austria.... It's cheaper on the Autobahn.

But we'll see what Vincent decides.

Would anybody please involve Keith in a wooden plane for next Year? I would miss his humor :lol:

Slope Soaring / Friday 3rd July 2009.....Mt. Lienster (South Slope)

« on: July 17, 2009, 19:05:39 PM »

Yeah Keith,

You found Andreas from Bruxxels (or so). I've seen him the first time at the german Flying-wing-meeting this spring. it was in his holiday time. He's very good in aerodymic things.

There is only one thing which he surprises me, how long his holidays are. It seems to me he is always on holidays... :lol:

...the world is getting smaller and smaller....

The smaller plane is a "Frettchen". I have one of those in my basement. May be I built it for my next trip to Ireland.

If You meat him again, give him my regards.

Regards

Ha!

here we are! Great, to find all the friends from Ireland at one place. The trip home was not to bad. Heidi and I arrived in Bremen on Tuesday at 12.00 hrs.

Thanks for all of You, who made Ireland such an unforgetable trip.

Regards
