中國推出第二架隱形戰鬥機
自從九月時有瀋飛四代的照片流出後，在網上曾刮起一陣討論的風潮，但最近亦已經沉寂下來。根據一些網上的流言，此飛機似乎已被身份不明的「某方」相中並且包養之，因此很難再有如先前一般大模大樣地在公路上任影的情況 {:22:} 至於眾人都關心的何時首飛的問題，相信廠方會在這個月內完成，不然到了冰天雪地的日子... 誰敢去做高危的試飛活動？

Original Title: China Unveils Second Stealth Fighter
September 24, 2012
Bill Sweetman and Richard Fisher Washington and Bradley Perrett Beijing
China's unveiling of a second low-observable (LO) or stealthy fighter, a Shenyang product possibly designated J-31, followed the same pattern as the revelation of the Chengdu J-20 at the end of 2010: Photos were leaked via the Internet on the eve of a U.S. defense secretary's visit to Beijing. The not-too-subtle message, as the U.S. follows through with its plans to shift air and naval forces to the Pacific region, is that China's own military modernization is not slowing down.
The first images of the J-31 show that the aircraft is very different from the large, canard-delta J-20. The Shenyang fighter appears to be much smaller than the J-20, with about two-thirds as much installed power. It is a quad-tail design with a moderately swept clipped-delta wing and large canted vertical tails, with a similar overall layout to the Lockheed Martin F-22—but more like the F-35A Joint Strike Fighter in terms of overall size. Weapon bays occupy the entire lower body aft of the inlets and ahead of the engine bays (unlike on the J-20, there are no side bays). Flight controls are conventional, with separate rudders and single-piece flaperons.
As in the case of the J-20, most of the stealth-shaping techniques are very similar to those on Lockheed Martin fighters, but the engine nozzles are conventional. The nozzle shape on the prototype is close to that of the Klimov RD-93 engine installation on the Chengdu JF-17 fighter, minus the tapered “collar” that fairs the latter's nozzle into the aft fuselage. Thrust vectoring has been studied in China but has not yet been demonstrated in flight.
One common feature of the J-20 and J-31 is that both, from images seen to date, appear to be beyond an “X-plane” stage. Both are equipped with weapon bays; both are full-scale demonstrators, and neither appears to use any components of existing aircraft. However, the timing of the development of operational variants and full-scale production remains uncertain. China is continuing the development of conventional non-stealthy fighters, and it remains to be seen when industry there can start producing competitive domestic engines and break the nation's dependency on imported Russian power. (So far, all production JF-17s have been RD-93-powered although a Chinese replacement, the Guizhou WS-13, is under development.)
Although there is no official information campaign for either of China's new stealth fighters, the “unofficial” information campaigns allowed to flourish on the Internet by government authorities have been markedly different, revealing much more about the Shenyang fighter.
In September 2011, China's Aviation Industries Corp. (Avic) sponsored a competition for unmanned aerial vehicle (UAV) models at the China Aviation Museum outside Beijing, and as part of the attendant displays, the Shenyang University of Aeronautics and Astronautics (SUAA) presented a model of a twin-engine stealthy fighter with the F-60 designator on the canted vertical stabilizer. SUAA has been involved in UAV, UCAV and now fighter design work for Shenyang.
Late in June, a crudely covered full-scale fighter, without its vertical stabilizers, was openly transported on a flatbed truck from Shenyang to Yanliang Air Base near the major aerospace city of Xian, home of the China Flight Test Establishment of the People's Liberation Army Air Force. At the time, there was speculation that this aircraft was intended for Yanliang's static stress-testing facilities. The aircraft shape was broadly similar to the SUAA model.
One reason for this difference, according to some Chinese sources, is that Shenyang's fighter may not be a fully air force-funded program, but an initiative derived from its losing competitor to the Chengdu J-20. The various plants of the Avic group, such as Chengdu Aircraft and Shenyang Aircraft, have a long tradition of rivalry. To overcome that, the group began bundling them together from 2008 into specialist subsidiaries in which they were supposed to work together. But the defense ministry opposed tight integration of the defense subsidiary—including Chengdu and Shenyang—in order to maintain closer control and probably to retain and foster competition among them.
But it is also possible that Shenyang's fighter does have an official sponsor: the Chinese navy. Shenyang is the builder of the navy's first carrier-based fighter–the Sukhoi Su-33-derived J-15. The J-31 would be more adaptable to carrier operations than the bigger J-20—although it might still need enhancements such as a bigger wing, an improved high-lift and control system, and thrust vectoring. Finally, the J-31 could be a smaller, less costly complement to the J-20.

現在連老外都猜測J-31要為航母工作且會比J-20更加好了，我都不知道該說什麼好了....不是確定要用J-15來作為艦載機的麼？那麼J-31有什麼優勢去和J-15對抗呢...

瀋飛成飛都同屬中航... 最多只能叫作不同地方派系。
J-31之類的名稱我一向是忽視之 {:23:} 至於說比J-20是更好的艦載機我可很同意：
1. 艦載機講求是低速的機動性，一向不是鴨翼機的強項
2. J-20的三角翼太靠後，翼面又薄又小，掛對艦彈的潛力不足...<div class='locked'><em>瀏覽完整內容，請先 <a href='member.php?mod=register'>註冊</a> 或 <a href='javascript:;' onclick="lsSubmit()">登入會員</a></em></div> 這應該是未來航母艦載隱形戰機吧
未來應該是要PKF35隱形戰機用的<br><br><br><br><br><div></div> j-15是過度機配合新開發j-31也許有可能 因為j-.31是新機要全部服役 短期內會有困難 所以二者搭配過度應該會更好 那這樣有個問題：殲31的定位是什麼?
如果解放軍空軍確定會對殲20下訂單，它的定位是類似F-22的主力地位
那殲31的定位是不是很有可能類似F-35，當作殲20的低配戰機用?
但還有一個問題：
如果殲31真的是低配機，那有殲10呢?
弄出個殲10之候，在弄個殲31的低配機出來，這樣豈不是要搞死後勤{:51:}
"不然到了冰天雪地的日子..... 誰敢去做高危的試飛活動"
俄羅斯試飛員表示毫無壓力XD 唉呦~~
台灣要加緊研發啦
不然在這樣下去
兩岸的軍力會越來越懸殊而已 等到J20,J31 服役, J-10也有一定年紀了, 到到時候可以大量出售用來賺錢, 最新改良版可以換裝給沒那麼大守備壓力的空軍部隊或預備役部,就像美國把退役的F-15給國民警衛軍用一樣, 耶台灣要不要考慮買?可以用巴基斯就模式,讓台灣選配西方的航電設備! 一定不會比F16差,反正紀德艦的電腦都大陸做的了!!加個J10也沒差,價錢也好談!大陸可能也會同意讓台灣設組裝線讓台灣自已裝,另一方面,台灣也可以用這個逼美國賣更好更實惠的東西給台灣! 一舉多得,台灣不會虧!...<div class='locked'><em>瀏覽完整內容，請先 <a href='member.php?mod=register'>註冊</a> 或 <a href='javascript:;' onclick="lsSubmit()">登入會員</a></em></div><br><br><br><br><br><div></div> 龍大對大陸的飛機尤其是新戰機很感興趣呀……
就這個傳聞來說，我覺得大概是爲了中共自研自製的新航母做配套戰機也沒准，不大可能會取代J15使用在訓練航母上面。 光腚娃娃 發表於 2012-10-28 08:27 PM static/image/common/back.gif

我對任何新型飛機都很有興趣，尤其是高性能又好打的 {:22:}
如果台灣也能有全新飛機而不只是翻新的貨色，我亦會很高興地貼出來 {:23:}...<div class='locked'><em>瀏覽完整內容，請先 <a href='member.php?mod=register'>註冊</a> 或 <a href='javascript:;' onclick="lsSubmit()">登入會員</a></em></div> J15目前使用在訓練航母~
訓練飛行員及航母的使用~
等到正式航母及J-31量產~
飛行員也有了~航母使用也駕輕就熟了~
那J15與J31混搭又有何不可???? 台灣的軍事力量
如過被中國拉開太多的話
可能會非常的危險..... 反正以目前台灣自己研發什麼都內憂外患的
其實大陸有再多的武器對台灣來講都是沒差別的
