J-20... The New Generation Fighter III

I do not enjoy the lack of raw footage.

Goodboy's video now on youtube. Embedded for your convenience:

Thanks for posting that link A.Man and to Siege for embedding it, beautifull video, nice music, what is it? I really like the back up light guys, and the ruddervator canted over like that reminds me of the 58 Chevy, which I think is purdy. I'm not a huge fan of canards, but I do notice that they have a lot of dihedral, which a little research said was to keep the turbulent flow off of the delta. Also some noted a lot of bobbing with associatted control deflection, I assume your're not talking about the bobbing that results every time you hit the brakes for speed reduction and preparing to turn, on all jet aircraft as you taxi. Thats just the nose gear oleo strut compressing and extending. One question I do have is that as the pilot checks that controls are free and correct the surfaces seem to flic very rapidly, is that the fly by wire? and related question, is the control stick side mounted? It looks a little odd because usually when you check for free and correct, you move the controls from full deflection to full deflection, feeling for any binding and visually checking that each surface moves through its full range from stop to stop.

Argh, Video is not available in Germany because of copyright infringement regarding the music. What the heck, 5hrs after uploading. And 51 is too damn slow. If someone finds the footage without the music, please advise.

Probably some other problem other than the website. The speed looks normal from my side.

I know that the military programs from mainland China are notorious for inaccurate info but perhaps there are some relevant info from this one?



　

中新网12月30日电 解放军少将、中国军事科学学会副秘书长罗援30日做客中新网《新闻大家谈》时向广大网友介绍了颇受瞩目的歼-20战机。罗援少将说，歼-20战机已经达到国际先进水平，与美俄最先进的战机相比各有优劣。但歼-20飞机将更多是进行国土防空，所以在某些方面中国不用去跟别人争“最豪华版的飞机”。

　　要客观对待歼-20实力 不妄自菲薄不妄自尊大

　　罗援少将说，要客观对待歼-20飞机，既不能妄自菲薄，也不能妄自尊大，更要清楚认识外国评论歼-20飞机的意图。比如说美国《时代周刊》曾刊文说歼-20将是航空母舰的杀手锏，但之后美国前国防部长盖茨又在国会发声，说中国的歼-20飞机起码要落后美国的先进战机20年。他说到2015年的时候，中国军队可能才能装备50架，到2025年时候才能装备100架，所以他觉得对美国的F-22构不成威胁。

罗援说，我们应该清楚的认识到国外对歼-20战机两种截然相反的看法——一种是宣扬中国威胁论的时候说歼-20已经能和美国的F-22相媲美，但是要唱衰中国的时候说歼-20与他们的战机水平还差20年。

　　歼-20与F-22相比各有优劣 “心脏病”问题未完全解决

　　罗援少将介绍道，美国F-22战机与歼-20战机相比，优点在于研发时间较长，技术相对比较成熟，而且这种飞机已经可以成规模的生产，而歼-20战机刚在研发之中。但歼-20的优势在于起点高，有后发优势，比如说美国的F-22战斗机它的特点是有隐形能力，但因为起点高，所以歼-20起码具备反隐形的能力。而且歼-20飞机体积要比F-22要大，这意味着歼-20比F-22飞得更远，载弹量更大。

　　此外，歼-20同样具有超视距的打击能力和超音速的巡航能力。但根据中国的国防政策，歼-20飞机将更多是进行国土防空，还是进行自卫作战，所以在某些方面中国不用去跟别人争“最豪华版的飞机”。

　　罗援少将还对歼-20已经接近或者达到了国际先进水平的观点表示认同。罗援少将说，歼-20飞机是中国国防军事实力的一个综合体现，因为歼-20不是单项飞机，而是各部门整个集成的产物，综合起来反映了航空水平，而航空水平又被人认为是国防科研之花。

　　罗援少将还说，在这个重要的部门里面，我们还没有完全解决一个非常重要的问题，那就是飞机的发动机问题。比如歼-20飞机在试飞过程中，我们想它可能现在还是用的苏-35的117S式发动机，这也是原来的AL31F发动机的改装型。现在据说我们也在对飞机的发动机进行自主研发，就像媒体揣测的那样，如果我们自己的WS15发动机能用到歼-20飞机上，那就解决了“心脏病”的问题，那就证明中国的航空工业，中国的国防工业都上了一个很大的台阶。

The PLA officer interviewed said that he believe the J-20 will be intended for air defense purposes. Its larger size indicate larger weapons load/range than the F-22. He also believes that the engine is an AL-31F variant (117s?). Over all he said not to over or underestimate the J-20's capabilities.

Interesting....So it not an 'Air Dominance Fighter' but an 'Air Defense Fighter'? Sounds a bit like an interceptor.....

You should view that as defensive mission vs. offensive mission. Achieving air-dominance does not contradict with a defensive objective.

Translation from Chinese to English and vice versa is not an exact science.

If you go by the official lines all PLAAF fighters are intended for "air defense" or "protection of homeland".
