Details emerge of Chinese J-11B heavy air superiority fighter
Johnathon Weng JDW Correspondent
Beijing
Details have emerged of China's next-generation J-11B heavy air superiority fighter aircraft: a further development of Sukhoi's Su-27SK (Chinese designation J-11) that ended production in 2004 ahead of its planned run.
Shenyang Aviation Corporation assembled 95 J-11 fighters from imported Russian components, although the original project had called for 200 aircraft, and it is likely production was stopped in anticipation of the improved J-11B.
Although based on the Su-27SK, the latest incarnation has substantial improvements including a reduced radar cross-section (RCS), a strengthened airframe and an improved fire-control radar, as well as a new flight-control system, glass cockpit and engine.
The improvements are planned to take the aircraft to a fourth-generation platform. It is known that the Yanliang Flight Test Center currently has three J-11Bs under testing (No 521, No 523 and No 524), but there may be others.
The most significant change for the aircraft is the reduced RCS; sources claim that this brings the RCS from the 15 m2 of the Su-27 to less than 5 m2 and possibly as low as 3 m2, but it is unlikely that the minimal changes proposed could achieve this.
The change is not to the dynamic shape of the aircraft but involves modification of the air-intake lip with a radar wave shield and installation of radar-absorbing materials on the intake interior. In addition, the RCS will be reduced with Chinese-made signature-reduction paint.
The strengthening of the airframe - a key aspect since the life expectancy of the aircraft has been criticised by the People's Liberation Army Air Force - has been achieved through wind-tunnel tests of the weapons carriage.
Additionally, the empty weight of the aircraft has been reduced by about 700 kg through the use of composite materials.
It is believed a further 10,000 hours have been added to the life of the aircraft compared with the Su-27SK.
The radar installed on the J-11B is believed to be more powerful than the Type 1473 installed on the J-10; it is estimated to be able to track 20 targets and simultaneously lock onto six.
The J-11B will incorporate a four-times redundant digital fly-by-wire flight-control system with mechanical backup. Additionally, the aircraft has a fully glass cockpit with two variants: a reflecting head-up display (HUD) with four multifunction displays (MFDs) and a holographic HUD with three MFDs.
It is likely the former cockpit will be used for ground attack and the latter for air combat. The new cockpits integrate fire-control radar, electro-optic countermeasure pods and infrared search and track.
The improved radar and cockpit have allowed for the integration of newer weapons such as the CATIC PL-12 active radar-guided air-to-air missile. The J-11 AL-31F engine will be replaced with the WS10A turbofan, providing longer lifespan and reduced fuel consumption.

简氏的一般还是比较可信的 -----
reflect???之前不是说是diffrect么??
唉，还是is said、is believed太多，is confirmed太少，大部分内容咱们的网站上传了n久了。顺便问一问，对空对地设计两种座舱是不是夸张了点？寿命比27增加一万小时？？

怎么是北京,王(wang)中国人自己写的,还以为是外国人写的,有水分!
我晕~~谁把那E文的给翻译下再上来?
大部分的东西这里已经有人在传：
原计划组装２００架苏２７ＳＫ，２００４年组合完９５架后停止，为相信更好的Ｊ１１Ｂ让路。
ＲＣＳ上重大改进（有渠道宣称从十五平方下降到５平方米，甚至有可能低至３平方米）。经过携带武器的吹风试验后，加强了机体强度，增加了备受解放军指责的机体寿命（比苏２７ＳＫ增加了一万小时寿命）。气动外形没有改变，修改了进气道唇口，进气道内使用了吸波材料和一个挡波墙，机体上使用了中国自己制造的吸波涂料。但在改动如此之小的情况下实现上述目标是很难让人相信的。
火力控制雷达比Ｊ１０使用的１４７３要强，估计可以跟踪２０个目标，并同时锁定其中的６个。
四余度冗余数字式飞行控制系统，带机械备份。全玻璃座舱，空地两种布局。
新的座舱把火力控制雷达、光电对抗系统和红外跟踪瞄准整合在了一起。新的雷达和座舱让新的武器如ＰＬ１２主动雷达寻的空空导弹的使用成为可能。原歼１１使用的ＡＬ３１Ｆ发动机也更换为ＷＳ１０Ａ，提供了更长的寿命和更低的油耗。
