*New J-10 Thread*

[kongliang]

WEIGHTS
Empty 8,300kg
Typical Air-to-Air Combat 13,200kg
Max take-off 18,000kg
Fuel capacity 4,500kg
Max payload N/A

The optimistic estimate of the empty weight of J-10 is 7.8T .

J-10 with 3 external fuel tank and 2 PL-12 + 2 PL-8 only has a combat radius of 1100 km.

When J-10 with 3 external fuel tank and 2 PL-12 + 2 PL-8 :the combat radius >1200km .

J-10 with 3 external fuel tank and 2 PL-12 + 2 PL-8 ......
That picture happened at this airbase .

That picture proves nothing. I can draw a picture like that too.
this 1100 km was supposedly announced by a report on J-10 on CCTV7.

That picture show the place of the airbase ,and some other ,and with the range of combat .

This 1100 km was supposedly announced by a report on J-10 on CCTV7.

It seems the combat radius of J-10 that without any external fuel tank .

 

[kongliang]

I think ,for J-10 ,the combat radius shorter than JF-17 is impossible .

The maximal combat radius of JF-17 >1200km .

枭龙飞机装一台推力大、耗油省的高推重比涡扇发动机，采用两侧肋下进气，机头可容纳大口径雷达天线。全机共有７个外挂点，可悬挂多种空空、空地武器，并可外挂３个副油箱，总外挂能力３６００千克，正常起飞重量为９１００千克，最大航程为３５００公里，作战半径大于１２００公里，已经达到了第三代战斗机的综合作战效能，具备了与当今先进战斗机抗衡的能力。

Is J-10 radar can match APG-68 in ROCAF F-16C, RDY 2 in M2K Dash Five and IAF Sukhoi-30 and M2K radar? thx

 

[simonov]

Is J-10 radar has a SAR capability radar for mapping?

 

[crobato]

Didn't you ask similar questions in the CDF? We don't know enough of the J-10's radar to make a solid comparison. We only have the sketchy information about the FC-1's own radar (not even the true designations of such) to give us some guide about the J-10's radar. Actually the comparison gets sketchier because the selected FC-1 radar might end up to being a different Chinese firm from the J-10's.

There is also some sketchy information about the radar on the late model J-8II variants like the J-8IIM.

Even from these sources, there is no indication that the J-10's radar has SAR. It probably has MTI or GMTI (Ground Moving Target Indicator), which means it can spot or detect individual targets on the ground, as opposed to seeing it like a large group.

A couple of things:
1) J-10 doesn't necessarily have longer combat radius than JF-17, because they seemed to have really reduced internal fuel tank to improve the maneuverability. So, sacrificing range and possibly payload for great A2A combat. Whereas JF-17 is needed by PAF as more of a multirole fighter. Note, in the radar specs for JF-17, there is not only requirements for A2A combat but also detection against sea and land targets. Whereas for J-10, from what we know in the past, it seem to be pretty much sacrificed A2G capability for greater range in A2A.
2) we don't know what the combat radius of JF-17 was measured under. We don't know the exact profile. Remember, flying at different altitute with different payloads and different configuration can result in vastly different combat radius.
3) J-10's combat radius with 1 external fuel tank + 4 PL-12 + 2 PL-8 was mentionned as 900 km.
It's not that bad really. For example, super hornet with 2 AIM-9 and 2 AMRAAM in an escort mission only has a 410 nm combat radius.

歼-10的机头直径接近圆形，从照片上通过比例计算直径接近一米，这样的头锥可以安装直径740mm或者780mm的天线，这样的天线直径比费佐伦提供给中国的甲虫ME的天线大。甲虫ME直径只有680mm左右，大约和美国的APG-66或者APG-68相似，探测性能也基本和美国APG-66相似，对于米格-21类RCS在3平米的目标，最大探测距离在74到80公里左右，下视距离约40公里。2003年底，中国为巴基斯坦研制的FC-1型飞机试飞了，其研制单位（歼-10的母厂）对外展示了一系列的航电组合，其中提供一种由中国国内生产的轻型脉冲多普勒雷达，具有全数字化多模态的脉冲多普勒雷达，这种雷达有着600mm的直径，具备高、中、低脉冲重复频率（全波形），并且可以智能转换脉冲重复频率，采用脉冲压缩技术以及频率捷变技术，重量轻，功能齐全。其对3平米目标探测距离达到80km，对于大型空中目标达到120km，对海面目标最远可达200km，下视时最远可以达到42km，基本性能和几年前的甲虫ME雷达几乎一致。为了和西方雷达相竞争，特别是和意大利的Grifo-S2000型雷达竞争，中国提供了同样丰富的对地功能，真实波束测绘，大比例多普勒锐化等等，还具有时髦的边跟踪边扫描的能力，可以同时跟踪10个目标并控制两枚主动雷达制导的中距导弹攻击两个不同的目标。这一型雷达被认为是歼-10雷达的缩小简化版，用于在出口FC-1飞机的时候增加政治筹码的灵活性和争取最大的利润，较大直径的改型出现在沈阳制造的新的歼-8IIM上，取代了原有的甲虫ME雷达。

　　由于性能和竞争对手相比毫不逊色，有不少地方还优于意大利雷达，特别是中国还提供和AIM-120、R-77类似的先进的中距空空导弹SD-10以后，在火控的集成上，无疑占据很大的整合优势。有鉴于此这一型雷达的价格并不比国外的竞争对手便宜，甚至还稍微贵一点，我们相信中国用在自己的主力战斗机上的系统，一定要大大优于可以允许出口的装备，这一点是完全沿袭苏联时代的意识习惯。一些小道消息认为，歼-10的雷达性能相当强大，它的天线直径和美国的APG-65差不多大，平均功率达到1500-2500瓦，而上面所列的轻型雷达功率一般不超过350W，采用栅控液冷中央行波管，探测距离rcs=3平米的目标不小于100km,有人说这雷达发现苏-27那么大的目标大约在160km左右。同样采用了脉冲压缩和频率捷变的技术，雷达采用计算能力强大的POWER PC类芯片的多余度数字计算机进行处理，计算机的处理能力远远超过法国RDY雷达宣称的每秒1亿次的能力，这是计算机产业进步的结果，今天我们用于打字的桌面电脑都具有超过15亿次每秒的计算能力，较晚出现的系统自然会有更佳的处理能力，强大的计算处理能力和存储能力可以帮助雷达在边跟边扫模式中处理更多的目标。根据法国的RDY雷达的能力，我们相信如果真的如同描述那么强大的计算能力，同时跟踪15-25个目标，攻击其中4-8个目标是完全可能的，费佐伦为苏-30开发的雷达计算能力还没有法国雷达那么夸张时就宣称可以跟踪15个目标而打击其中4个 。

From the article above ,FC-1's radar is similar to the APG-66 .
The J-10's radar is biger and more advanced than FC-1's .

But they are all sketchy , and I know little bout J-10's radar .

Just a short question: Does anyone know which Institute developed the digital Type-634 quadruplex “fly-by-wire” (FBW) system „Iron Eagle“ for the J-10 ??

Thanks in advance, Deino
