Absolutely NOT. The caption clearly says it's the RUSSIAN concept, therefore TsAGI.

My dear Skyblazer,


it was from France and Russian,in cooperation for BWB,and you are right not Boeing,I will
correct it.

Hesham, it was proprietary TsAGI design as you was told already. Dubbed LK-103 configuration. No NASA or whatever else was involved.

".. subsequently a Russian BWB project was published, designed with French support. Dimensions
even exceeded those studies by Boeing and Aèrospatiale. The concept by TsAGI would have had a
span of 106 m ..."

There's a French participation mentioned, but it is said loud and clear, that it basically was a TsAGI
project. Another case of a misinterpreted online translation ?
Please, please ask in such cases before posting ! Otherwise Russian/US/French joint projects in the field
of BWB (or others), mentioned this way here may well fly forever in the skies of the internet !!
::)

OK my dear Jemiba,


and my apology to my dear Flateric,but the fault is for Google translation,they translate it as;
"Russian with French cooperation".

While I have read various things about the BWB designs: I am curious as to what the early designs looked like, and how they overcame issues such as pressurization of a squarish pressure hull

Here is a TsAGI BWB aircraft from 1995,the third drawing,I don't know if it was from the same
founder or not ?.

The last drawing is a version of the Handley Page Aerobus. It went the opposite direction of most airliners, it went with a low aspect ratio wing that was really thick, which allowed for a very light structure, comparatively speaking. Which would have made it less expensive to build. However, it wasn't as aerodynamically efficient due to the low aspect ratio wing. But it was designed for short haul flights (London to Paris) so it could still compete with standard designs. I've always thought it was a very smart design for a short range airliner.

So to answer your question; It's definitely not the same founder. ;)

Hi,

here is some BWB designs,with a concept called CWB.

Pawlikowski had one big hole in her hope chest: funds to build a prototype blended wing, an elegant looking design the Air Force has been working on occasionally since at least 2008

Hi,

The future development of Boeing’s blended-wing-body (BWB) configuration depends entirely on its suitability for carrying cargo, and in the case of a military tanker-transport in particular, its ability to perform airdrop missions. Key to this capability is an innovative cargo door that Boeing has designed to open like a clamshell in the trailing edge. However, it was unclear what effect such a radical door design opening in midair might have on the airflow around the trailing.

Thanks for the picture. Was there a blurb accompanying the model? Curious if they said anything about the propulsion beyond "hey it's back to turbofans."

No, just a company tweet today, along with images of the previously-disclosed hypersonic aircraft and of the transonic strut-braced transport discussed elsewhere.

Kind of a different front end there.

Can you elaborate the difference?
generally a BWB that is a wing w/ a uniformly thinning from the center all the way to the wing tip like the B-2. Hybrid is conformal body w/ wings attached like this Maveric.
You consider the B-2 as an example of a BWB? I would think it is the classic example of a flying wing.
However, I get your point... But looking at the Maveric, I'm not sure if I can agree. The transition from body to wing looks quite seamless to me.
The only thing that puzzles me is that dull leading edge.

If is walks like a duck, and quacks like a duck, it is a duck. The Maveric is the definition of a blended wing body design.

We are not talking about ducks. Maveric's body and its wings are quite distinctly dijferent, it is not a BWB. Maveric looks nothing like the B-2.

There are hybrid wing bodies (HWB) and Blended Wing Bodies (BWB). Saying Flying Wing is like sayin my car is Hot Rod:rolleyes:
