Details emerge of China’s J-11B heavy fighter
Details have emerged of China’snext-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 theYanliang FlightTest Center
currently has three J-11B aircraft under testing.
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 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. 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.

大意：
大量细节显示中国发展下一代重型战斗机————j-11b,其为Su-27SK的重大改进型。
相较于Su-27SK ，j-11b在多方面进行了改进：减少雷达反射面积、强化机体结构、升级火控雷达，并且采用了新型飞控系统、玻璃座舱以及发动机。
最显著改进是雷达反射面积从Su-27的15平米减少到5平米，甚至可能低到3平米。但仅作细微的改变（外形？）不可能达到这一目标。该方面主要改进是调整进气口（增加雷达波防护罩？）以及在进气道使用吸波涂料。中国自产信号弱化涂料？能发挥减少RCS 功效。
载武器条件下的风洞试验证明机体强化目标已达到。此外，通过使用复合材料，飞机空重减少700公斤。飞机寿命增加到10000小时。
据信j-11b装备的雷达较j-10装备的1473雷达更为强大，预计能够抓20打6。

说不定是从ＣＤ看来的消息
LS还有翻译的啊，呵呵
