Re: New Generation Fighter

I believe "da lian tiao" refers to LERX (leading edge extensions). In other words this plane probably reduces the amount of lift energy being sucked out by vortices generated from the canard using LERXs.

Thnx! Would you mind helping out with the translation? The task is a lot bigger than I first thought.

I was going to translate it last night actually, but have been relatively busy and my vocabulary is weak so it takes some time ^^. I can probably start on it later tonight/tomorrow, so if you're not done by then I'll take care of the rest?

Sounds like a good plan!

Before I start the second part of the translation I would like other forum members to take note that the description of the J-XX produced by CAC is very similar to the picture shown by 70092. Although the story sounds very fanboy-ish there might actually be some truth to it.

Translation Part 2:

huzhigeng:【重型机是全国大协作,方案是611所的,飞控也是611设计的,结构设计是60 1和611共同设计,(因为双发战机601经验更多,今年重四发图。601所也参与进来了,而且机体结构还 是601所为主,东北在机体结构,复合材料部件.钛合金部件方面比成都有优势。所以上次发图,601所忙死 掉了,自己的四代要发图,还要帮611所重四一起发图,还好任务已经完成(所以离子鱼才会吹嘘东北得了多少 多少,东北人自己有四代,而且重四自己也有份)两边都得。】


  枫兰:东北的丝带是不是舰载机啊?难道中国还要搞几个四代?轻中型?重型?舰载的??


  huzhigeng:【东北的最近发了图的是给空军用的,海军的没那么快。】


  别离钩 :huzhigeng 老大,你是说机头、前机身和全尺寸样机有差别,后机身比较接近吗?请赐教


  huzhigeng:【611所一般喜欢用机机验证四代技术的,歼十、小龙...不过这个 J J 的边条和样机有差别的,四代是类似于小龙和超级大黄蜂那样的尖拱边条,很大的边条哟,发动机屁股是圆的轴对 称三百六十度矢推,不是二元的。】


  青之六 :正在造的应该是01原型机吧?因为据某狂热分子疯狗*所说,全尺寸金属样机已经搞定N年了? !


  huzhigeng:【全尺寸金属样机确实早已经出来了,可是有人敢进132拍照吗?进得去吗?这个J J可不会停在草地上让你拍的。01架确实已经在造,样机科幻又比较怪异,特别是从前面看。】


  klonoa1121:对了离题一下, huzhigeng你知道J10-21是什么东西吗


  huzhigeng:【 我只知道歼十B不是歼十系列的最终改型。】


  别离钩:请教 huzhigeng 老大 ,四代机的总设计师是谁?是宋文骢?杨伟?还是新调来的季晓光?


  huzhigeng:【伟哥,但是宋也有很大的功劳,基础是他打下下的。当然,11整个团 队的功劳。】


  cyjsk: 老大可调DSI是什么概念?难道是鼓包可调?那可真是太科幻了。


  huzhigeng: 鼓包当然不可调,但是进气道可调,这样最大速度就上去了,一举两得。】


  刀锋2009:跟人请教下HUZIGENG哈:你对六代(美标五代)是什么概念?


  huzhigeng:【美国人也在论证,到时候就知道,我们也在论证,不过八九不离十,都会差不多的, 六代分有人和无人两种。】


  freedr :huzhigeng大大,为什么空军会有两个四代,难道一下搞定高低搭配,还是真如离子鱼所说611的可 能只是验证机,或者不会大批量装配的机型。

  huzhigeng:【呵呵,611验证机?成都重四和F22一样,不会生产太多,最多三百来架。因为 这是重型机,重在精不在多。不像东北的,是量多质稍过去去。我从来没有听说重型机会比中型机装备得多。F2 2装备数量有F35多?呵呵。】


  刀锋2009 : 发动机还有很多不确定因素,话怎么能说的太满了?


  huzhigeng:【首飞发动机肯定不会用WS15。没有一个国家首飞会用新的发动机。美国佬的YF 22也不是。毛国也不是。同理我们也不会用。发动机也不会慢。】


  jcyjsk : 谢老大耐心讲解。你说有毛子在611参与丝带,难道不怕泄密啊?俄罗斯这个白眼狼,咱不得不防 啊。


  huzhigeng:【很早前611就有毛国人。九十年代就请了一些。611的毛国专家主要是机体结构 方面的专家。他们是拿我们的工资的。呵呵。。。。】


  gotowork :huzhigeng老大 请教一下 611对于重四的标准(如隐身、超巡、超机动、超视距)和美国一样吗?还是带有中国特色?


  huzhigeng:【四代的标准就是隐身、超机动、超巡、超视距。你想想,这是标准。所以我们的四代 会少吗?只是我们更侧重于超机动、超巡(所以我们的四代都是比较细长的)。611四代其实是取美国和毛国的 精华,有独特中国特色的四代机,有鸭翼,有尖拱大边条,DSI可调进气道,这些难道不有特色? 】

huzhigeng: The large Chinese passenger plane is a national effort. The plan and flight control were developed by 611 while the structure was a cooperative effort between 601 and 611 (This is because 601 is more experienced dealing with twin-engined fighters (*he also mentioned something about "heavy four", as in heavy fourth generation (fifth gen) jet and I don't know how to translate it). The plane's structure was primarily designed by 601 since Dongbei (Manchurian province of China where Shengyang is located) has the upperhand when it comes to structural design, composite materials, and titanium alloys. Last time 601 was really busy posting pictures (more stuff on the "heavy four". I don't think it is very important).

枫兰: Is Dongbei's fourth generation (fifth gen) plane carrier-capable? How many fourth generation (fith gen) planes does China need? Are we going to get light-medium, heavy, and carrier capable fifth generation fighters?

huzhigeng: The picture recently released by Dongbei is that of a Airforce Fighter. The navy won't get their fighters this fast.

别离钩 :huzhigeng, you said that the head, the front of the plane, and the models of the two planes (SAC and CAC fighters) have major differences. Are the planes' rears similar to one another?

huzhigeng: 611 usually likes to use their planes to test 4th gen (fifth generation) technology... J-10 and JF-17 are good examples. However the LERX on this plane are different from those of the sample plane. Fourth generation (fifth gen) fighters have large, sharp, protruding LERX not unlike those found on the JF-17 and Super Hornet. The engine nozzle has circular symmetry about the axis and could produce 360 degree *矢推,不是二元的。

青之六: The plane under construction should be the 01 prototype, right? According to J-xx fanatic 疯狗* the scaled model was made years ago!

huzhigeng: Right. The scaled-model has been made years ago but who dares to go in 132 and snap a picture? Can anyone get in? They won't just park the model on the lawn and let your snap pictures! They really are producing the 01 prototype. It looks very strange and "Sci-Fi", especially from the front.

klonoa1121:Let me go off topic for a sec. huzhigeng, do you know anything about J10-21?

huzhigeng: All I know is that J-10B is not the last J-10 variant.

别离钩: huzhigeng, who is the chief designer of the fourth gen (fifth gen) fighter? Is it 宋文骢 (designer of J-10), 杨伟, or the new comer - 季晓光?

huzhigeng: 伟哥 (Chinese phrase for Viagra :D. No, its 杨伟). However 宋文骢 is an important contributer. He laid the foundation for the whole project. Finally the J-xx won't be possible without the hard work and dedication of the entire 11-th regiment.

cyjsk:Hey boss (huzhigeng), what did you mean by adjustable DSI? Could the little "bumps" really move? If that's true then the J-xx is "Sci-Fi" indeed!

huzhigeng: Of course you can't adjust the bumps! However the intakes are adjustable. This way you can raise the maximum velocity. Killing two birds with one stone!

刀锋2009: huzhigeng, what is your opinion on 6th generation fighters?

huzhigeng: Americans are talking about it and we'll know when they are ready. We are talking about 6th gen fighters as well and our predictions are probably the same as their's. There should be two types of 6th gen. fighters - manned and unmanned.

freedr: Hey huzhigeng why does the air force need two Fourth generation (fifth gen) fighters? Is it because the air force needs high-lo combinations or is it because the 611 model is just an experimental plane or a plane not intended for mass production?

huzhigeng: What? A 611 experimental plane? Chengdu's heavy fourth gen. (fifth gen) fighter is similar to the F-22 and not many will be produced. I predict that only 300 will be produced. This is because Chengdu's plane is a heavy fighter and a heavy fighter emphasizes quality over quantity. The reverse is true for Dongbei's planes. I've never heard of countries that produce more heavy fighters than medium-light fighters. Are there more F-22s than F-35s? :rofl:

刀锋2009: Don't talk big when there are still problems with indigenious engines!

huzhigeng: The prototype won't use the WS-15. No one ever test new engines on their new fighters! The YF-22 didn't use new engines and neither did Russia's fighter (PAK-FA). We probably won't use new engines either. Our engines won't be slow (so don't worry)!

jcyjsk: Thank you huzhigeng! You said that some Russians are working on the Fourth Gen. (Fifth gen) fighter. Aren't you worried that they might leak information (look whose harking :rofl:).

huzhigeng: There have been Russians working at 611 since the 90s! The Russian engineers at 611 are primarily airframe/structural experts. We are paying them well right now :rofl:.

gotowork: hey huzhigeng! Do we classify Fourth gen (Fifth gen) fighters the same way as the Americans (the 4S) or are we developing stealth fighters with "Chinese characteristics"?

huzhigeng: The characteristics of fourth generation (fifth gen) fighters are stealth, supermanueverability, supercruise, and AESA radars. Think about it! Those are the standards! Do you seriously think that our planes will be inferior? Our planes, however, emphasize supermanueverability and supercruise (that's why our 4th gen (5th gen) fighters are long and skinny). The 611 fighter will incorporate the advantages of American and Russian 5th generation fighters, use canards, large, sharp LERX, and adjustable DSI. Don't you think this plane is unique?

Re: New Generation Fighter

Thanks for the translation. I don't know how legit it is but it makes interesting reading.

One of the pics of this CGI was posted with this interview over at FYJS. Personally I'm hoping for this but this isn't a belly intake like mentioned in the interview.

Yeah I don't know what to make of this stuff either. If you didn't give me the details and just a outline of huzhigeng's conversations I would've dismissed him as a Fengqing but after reading some of the stuff he posted ... I am not so sure. This guy appears to know what he is talking about.

What I find interesting is that in the very beginning he mentioned a person named 高山 who also claimed that the J-XX will have belly-intake. He vehemently dismissed that and claimed that although the intakes will be DSI, they will also be "adjustable". He said that the openings of the intakes could increase/decrease and I am unsure of how that could be accomplished. Is there any experts here who could enlighten me on how such a thing would theoretically work?

Thanks for the translation siege.

I know about intake ramps my friend. This, however, should be something different since DSI is already being used! What is the point of using DSI if you've already got intake ramps!

在加莱特和DSI两者选择方面,成都的可调DSI ,比不可调的加莱特进气道更先进(601的专家现在也在611所)

When choosing between the Garrett and DSI inlets Chengdu's adjustable DSI inlets are far superior to the unadjustable Garrett inlet (Engineers who formerly worked at 601 currently work at 611).

Re: New Generation Fighter

Guess I'll help with some parts.

I'll have to do it piece by piece though. The abundance of Chinese defence terms (some of which are colloquial) is driving me insane!!!


I am going to mark parts that I don't understand with an asterisk

First part:

A lot of huzhigeng predictions came true. We can't see *"double four" this year, it looks like he isn't bragging.

huzhigeng: Chengdu's (referring to CAC) "airplane" (referring to J-XX) is better than the F-22 manueverability wise and this is the result of canards, lift-body configuration, and *adjustable DSI. The inlets look very strange and the whole plane has this Sci-Fi look to it. Its appearance is even more "Sci-Fi" than that of the F-22.

huzhigeng: The Shengyang (SAC) "triplane" (referring to the tri-plane canard) that failed at the competition was too big, too heavy, too long, and too skinny. Its flight controls were too complicated and its stealth capabilities were inferior to that of Chengdu's (the double-delta design adversely affected stealth capabilities). Manueverability wise both planes had their own advantages. The Chengdu prototype had superb instanteneous and sustained turnrates and its specific excess power is even better. This is why the plane had a *大边条 to assist the canards. When choosing between the Garrett and DSI inlets Chengdu's adjustable DSI inlets are far superior to the unadjustable Garrett inlet (Engineers who formerly worked at 601 currently work at 611).

huzhigeng :The "bump" in a DSI is fixed and couldn't be moved. However the intake itself (I believe he is referring to the opening) could be adjusted. This is why the plane looks so strange from the front.

huzhigeng :Gaoshan's (plane) uses a belly intake. Fourth generation (Fifth generation) fighters will never use belly intakes! Gaoshan's picture is very similar to the "Big 10" (Super 10) pictures that we used to see.


huzhigeng :China could've come up with a conventional configuration similar to that of the F-22 back in the 90s! The F-22, however, is a superb plane not because of its configuration(which was state of the art back in the 80s and 90s) but *configuration+flight control (Fly by wire?), a powerful, thrustvectored engine, and state of the art avionics. Let's assume that we make a plane with a conventional configuration not unlike that of the F-22. Our engines are far worse than that of the U.S. (the WS-15 has similar capabilities to the F-119 but the F-119 is 90s U.S. technology). Our planes won't stand a chance! Chinese standards for her Fourth Generation (Fifth gen) fighters are very high so Chengdu is going to employ a "perverse" (very complicated) configuration.


huzhigeng :The 611 research division has been familiar with the Garret inlet since the 1990s. Don't think that the Garret inlet is invincible! The deign has its defects.

huzhigeng :We should be able to see the prototype by the end of next year. The drawings were done since July and work on the prototype already began. Many experts from 601 are staying at 611. Many "Hairy" (Chinese phrase for Russian) scientists are also working at 611. A lot of people attended the last meeting.

*Double Four, means Heavy 4th Gen, as in large aircrafts like Su-27 or F22.
(as a side note, Chinese 4th gen is equivalent to Western 5th gen)

*Adjustable DSI, the outer structure cannot be moved, but the inside of the intake can be adjusted.

*大边条, Side extension, like that of the F-18 hornet which is used by the US navy.

Re: New Generation Fighter

Perhaps to generate even more compression through shock wave, that is if DSI can't do adequate job on its own. Both creates inlet compression but the mechanism is somewhat different. A DSI can also be used to 'hide' the compressor blade, for stealthiness, intake ramp can't do this.

That's as far as I know.
