The wing does not have a back projection at tip I think. It just looks that way because the wing flaps are not installed.
I think this plane will be the low end of the high-low mix with J-20.
WS-10 is more powerful, but is it significantly heavier than ws-13? This plane is visibly smaller than J-20 or J-11B which currently uses WS-10. (J-10 is single engined). Weight could be an issue with this fighter.
I do not think it is L-15 because you can see a short protruding sting between where the two engines is to be placed. You don't see that on the L-15, whose engine nozzles are closer together.
No, just like the J-20, F-35 and PAKFA.
Actually if the small model is anything to judge by it might have a more conventional piece. There isn't really a lot to judge on right now.
Looks like all control surface is absent on the thing covered, as well as the canopy, therefore the wing shape looks incomplete. Right now it could simply be the main body shell yet to be assembled somewhere else. Btw maybe this indicates that it will have all moving tail and horizontal stabilizers.
Tiangong1 will be discarded next year, it is more likely a proof of concept prototype. The core of future space station will be composed of Tiangong2 and 3, both of which weights about 20k Kg, compared with 8K Kg of tiangong1.
Feel sorry for the girls. I think NK is trying to attract more investments, not just the initial payment. They need to open up economically and China could offer them advice on modernising the country.
Great Britain will never allow a single dominant power to unify continental Europe. Be it Germany of WWII or France under Napoleon or Soviet Union during the cold wars. Germany's position in Europe guarantees total war when they tries to become a dominant power among other strong countries.
Imagine if you want to show someone an engineering development model. Now along with sending him drawings you can send him the files for printing a small 3D version of it so he can get a better idea.
Also it will be much easier for people to make movies like chicken run.
When China started developing her type 99 Tanks it was using German engines at first. The Chinese found that given a engine, even if they just disassembled it into separate components and then reassembled it back together, the power output drops significantly. They have to get german technicians...
