Maybe so, but you would not have the fun of pestering "Aluminum Overcast" at all the airshows!:D
For that I want a Me-163, just not peroxide powered. Maybe one of the hybrid rockets (solid fuel, gaseous oxidizer) they were developing a few years ago.

Too bad those appear to be all new general layout drawings instead of the original construction plans. I imagine a GO229 would be a hell of a warbird and from what I understand, technologically it ought to be just about within the grasp of garage-buildable. I seem to recall the centre section has a welded steel tube frame to carry the cockpit, landing gear, and engines while the skin and entire outer wing panels are wood. Not really rocket science and *should* fall into about the same league as the full-Scale Jurca Spitfires, I would think.

When I say that it was signed by one of the Horten Brothers, I just assumed it was a copy of the original. Should have thought it over a bit. Construction blueprints would be dozens and dozens of pages!

i wonder if the Smithsonian has construction drawings, since they are allegedly rebuilding the only remaining example.

Yes but engine out situation etc demand more stability.

Albion is an interesting caracter.

Gliders are a different kinda system altogether...all "hot" Horten and Northrop designs crashed...ok B-2 is a different again as it uses very sophisticated computer systems to steer it.
They crashed because they were still trying to figure things out, not from lack of rudders. If you read Nickel's "Tailless Aircraft" book, you will see that the early Horten designs were way out of the "acceptable" parameter envelope.

Why would the stability for engine out need to be any different? Please explain.

The Northrop and Horten wings actually flew quite well. Horten has the problem of no money and bombs falling all around. Pretty impressive actually. Northrop crashes tended to be aft CG and to be more exact let’s fly the airplane with the CG aft of the no go zone, just to see. In the good range, they had it covered. They were real test pilots, actually testing not proving. Underpowered piston engines and early jet engines were not helping the situation.

I think there is at least one active full scale replica project and many models flying. Northrop and Hortons have drag rudders at the wig tips.

I don't know the current status, but the Smithsonian is currently rebuilding the only remaining Ho-229 with the assistance of a volunteer organization created for the purpose.

Are you seriously asking that ?

Planes are unstable to start with.

The Horten I was unstable, they learned from that and the rest were stable.
Just about all documents were destroyed in the German retreat. If Reimar had surrendered holding a loaded briefcase, he would likely have got a job somewhere other than Argentina...

I believe it is safe to say Al Bowers has put more years, and more brain cells, more mathematical calculations, and more study into flying wings at this point than all of the original nurflugel pioneers put together.

He has also had the benefit of seeing all of this from a unique vantage point (no bombs falling on the factory, a lot more complete body of scientific data on file, the ability to analyze all this using modern flow-vis and modeling, and with all of existing history at his disposal to research).

So if he has developed a theory, or has boiled down all this history and hundred year old math down into a set of equations, I tend to believe it as being far closer to the gospel than anyone else's opinion.

Anyone and eveyone interested in flying wings, Horten/Northrop stuff, and how air really wants to flow around an airplane wing... PLEASE take the time to come and meet Al, hear his presentations, and hold the fire under him for answers... at the ESA western workshop on Labor Day in Tehachapi, CA. You will never regret being at this event.

I would certainly like to meet Al Bowers. But you gotta admit his obsession with a pure flying wing...is an obsession.

Enthusiastic, not obsessed. Labor Day weekend in Tehachapi; all enthusiasts welcome to the 39th Western Workshop of the Experimental Soaring Association, div. of the Soaring Society of America. Vintage Sailplane Association meet same time and place.

By the way, the lift distribution Al is suggesting is not just for flying wings. R.T. Jones a noted NACA/NASA scientist was on to this too.
