Sounds great... if it's true. Here's a Google translation.


[China's new Flying Leopard III, the successful development: the first six to equip our troops trial

It is learnt that the recently about six "new feibao 3" equipment in Hainan Island Naval Air bases for a large number of adaptive equipment before the final test flight! Believe that in the near future there will be a lot of "new feibao 3" HNA equipment, as well as special warfare forces, the Air Force

Looking feibao -3 overtake -34 -
To ensure against "Feibao A" lack of a new Flying Leopard for the development of 3. In order to ensure that the "Flying Leopard III," the success of China and Russia (including part of Ukraine agencies) After years of hard negotiations, the highest in the Russian leadership's intervention, and reached a joint development of the "Flying Leopard III" of the cooperation agreement.

"Feibao III" is to complete the offensive-defensive needs of the Air Force, the Chinese Air Force in order to compensate for the lack of long-range strike capability, the lack of new bombers, and the lack of tanker and a lack of overseas air bases, and other weak link, and has made a long-range bombing Their self-defense capability of long-range sea-double on the multi-purpose heavy fighter-bombers (not strategic bombers, can be light tactical bomber).

China Rafah in the joint development of the Russian SU-34, China against Russia's Sukhoi economic difficulties, China urgently needed in the SU-27 and SU-30 fighter planes, such as orders and new project development costs and other special circumstances, the proposed joint development of "Flying Leopard III "programme, China's major commitment to research and development costs, but" Flying Leopard III "of intellectual property rights belonging to China (not to SU-27 and SU-30 authorized assembly). "Feibao III" than the SU-30 and SU-34 greater range, greater load of bombs and shells containing a machine capacity, stealth penetration ability and more than two times supersonic cruise capability.
Performance (Overtake Britain and the United States rush)
From the weapons configuration, "Feibao 3 A" short-range self-defense weapons system to a 110-kg 6-23 6 23 mm modified "Raytheon" cannon, the largest as soon as the 6000 / min. Other special type of individual, "Feibao 3" does not require Gun, but they can under the retrofitting of the 30 mm single-or double-barreled 23 mm calibre Gun Pod. "Flying Leopard 3" with a total of 15 pylons than feibao the nine pieces have significantly increased. This is the only F-15K in the United States the world's second with a total of 15 pylons of the aircraft. Therefore, the weapons of choice in addition to the types of use of AM-39, C-601/611, C-801/802, the new C-803 supersonic anti-ship missiles, also can be equipped with Russia's KH-65SE subsonic cruise missiles, and KH-31A (AS-17) supersonic anti-ship missiles, KH-31P supersonic anti-radiation missile and a more advanced KH-41 supersonic anti-ship missile. Type 2 modern destroyers, three M90 Series modified anti-ship missiles can be mounted to the "Flying Leopard 3" use. Other applicable short and medium-range ground attack weapons also include active and Development of the traditional domestic and foreign bombs, laser-guided bombs, air defense weapons and other outsiders projection. Meet with the guidance of equipment can be replaced in the "plug-in modules" to facilitate the solution, or at least including the use of low-altitude navigation pod, digital ago as infrared / laser targeting pod combination means to resolve.
From the fire control systems, now the world's advanced fighter planes are used all-digital autopilot and four of the more than fly-by-wire system, the system uses redundancy and central microprocessor, as the U.S. military's MIL-STD - 1750A software instructions control. With more than 40 homemade fly-by-wire system for the application of system reliability improved obviously.
Upon request, "Feibao 3" glass cockpit within the cabin of a three-under standard configuration, and the F-10 at the same level. Domestic two seats are equipped with wide-angle HUD and three-color high-brightness displays and printed-sight helmets. . Can be used to display multiple composite video recording subsystems to be monitored, "Feibao" head-up display with Autopilot crosslinking, even if the aircraft changed direction, and line-of-sight still in a stable pressure goals. In addition, it is still used with continuous calculation, calculation hit consecutive points, and other functions, and to install a set of angular velocity bombing system to enhance accuracy rate freefall weapons. The newly revised yaw angle sensor system that can fire weapons of sideslip angle on impact, but also for navigation weapons accurate calculation wind speed, wind direction purposes. In order to play a "Flying Leopard 3" the greatest power on board the installation of a modified "sea Overlord - B1" for the exchange of information for airborne high-speed data links with the new machines, as well as fiber optic cable for high-speed signal processing computer and multi-mode precision-guided detection system module, the "new feibao 3" has become China's first domestically produced with a dedicated high-speed data links of combat aircraft. So the "new feibao 3" a boot with the detection, and directing more than feibao 3 to meet the enemy capability.
From the appearance of view, China's "new feibao 3" to switch to a new design with middle-sweep of the front flap on the monoplane. Furthermore, in order to improve performance and strengthen the stealth aerodynamic shape, "New feibao 3" using the "S"-shaped inlet, and in the inlet within the new nano-absorbing paint spraying, in order to reduce radar reflection aircraft positive cross-sectional area and infrared Signal characteristics, and have adopted the wing-body fusion technology, all-new composite material applications has increased significantly. Will be late, "Feibao 3" and external "hard" to improve refueling equipment containing a telescopic "soft" refueling equipment, in order to further strengthen the stealth of the complete machine. Therefore, the "New feibao 3" is China's first use of computer-aided design that form a semi-stealth fighter.
From stealth performance, due to the "new feibao 3 A" use of a newly developed radar absorbing coatings, the aircraft was made to the probability of detection greatly reduced. In addition, the upgraded models of the late "Feibao 3 B / C" will increase the utilization of new composite materials, the fuselage and cabin cover the combination of sleek, cover edge of the cockpit, weapons and weapons-door edge, etc. The use of serrated combining lines, can effectively reduce the reflection of radar wave. Improvement of the latter part of the "Flying Leopard 3 B / C" vertical tail surfaces will be designed into the tilt. Because airborne weapons used contained, half-buried and pylons balanced way, about 80% of the aircraft stealth effect will be to decide on the shape and the remaining part of the stealth effect will need new radar absorbing material (RAM), radar absorbing structure (RAX), and other methods to solve achieve. , The circular nozzle will also be newly developed 3D stealth replaced by vectoring nozzle, in order to further reduce the IR characteristics. Expected due to the effective stealth measures, the latter part of the upgraded models of the "new 3-D Flying Leopard" radar cross-section (RCS) X will be not more than 0.00 square meters.
Outlook (前程似锦)
In future, the upgraded models of the "new 3-D Flying Leopard" will eventually equipped with a new type of China-made "multi-functional integrated frequency radar system" (MIRFS). Its main domestic system is the "active electronic scanning array" (AESA) Active Phased Array Radar! This radar will be able to provide a wide range of functions, including multi-mode radar, active jamming, passive electronic defense and encrypted communications. MIRFS can operate over a wide frequency band and a signal pulse, in order to ensure the "low rate was intercepted," making the "Flying Leopard new 3-D" will have "found but not found" capability. In addition, the new defense and air combat for the "search detecting infrared tracking analysis" (IRST) systems are also being developed. IRST system also known as "distributed aperture infrared system," namely "DAS." DAS system installed in the fuselage, including the location of different infrared sensors to provide the full range of Aircraft Infrared detection and tracking capabilities. This is the American F-35 is being developed by the system's combat DAIRA effect seems to be "in line." In the upgraded models of the "new 3-D Flying Leopard" in the fuselage targeting equipment will be further "integration", the new target will be the "photoelectric aiming systems" (EOTS) alternative. EOTS will include a forward-looking infrared imaging devices (FL IR), a CCD camera, a laser aiming, targeting a microwave device, a laser and electro-optical tracking a microwave detection-tracking group, etc. %. EOTS not be installed in the base of the exposed, its internal probe installed in the plane, was not thoroughly wave window covering, in the course of the whole mission will be operational. EOTS technology from China China-made "Eagle Eye" targeting pod and the Russian SU-30MKK2/MKK3 "Blue Shark" pod as well as the European technical support.
Airborne through the high-speed data links, "Feibao 3" can be linked with other data equipment of the aircraft will be information sharing and real-time battlefield information is rapidly passed back to the rear of the combat command center, so as to achieve the so-called "battlefield electronic information Control! "
Clearly, the "new feibao 3" electronic warfare system performance is the best among active fighters, but with the world's advanced level there is still a certain gap. Therefore, the country will also develop an infrared / laser active jamming planes and multi-mode tactical jamming pod. In addition, because the "new feibao 3" with the load of bombs, machine contents of the characteristics of the plot, except to consider pegging anchored-air refueling tanker equipment as partners, will be considered for the development of its revised " Flying Leopard 3 E "for reconnaissance and electronic warfare jamming planes. If possible, the future of the "new feibao 3 E" will be a continued EF-111 electronic warfare aircraft and F-18EF dedicated electronic warfare aircraft and a dedicated electronic warfare aircraft! Of course, this must be the "new feibao 3" beyond the purpose of use to decide. Moreover, if the Chinese strategic supersonic cruise missiles once successfully, then the "new feibao 3" series of operational combat aircraft will be able to significantly extend the scope, and China can make up for the time being there is no shortage of aircraft carriers and the development of domestic carriers and equipment before " gaps. " Thus far, the "new feibao 3" has become the new "force multiplier"!

Re: JH-7/JH-7A Thread

海军航空兵“飞豹”在对舰攻击中具备同时实施有源干扰能力
仲春之夜,渤海湾某机场,北航某团新型歼击轰炸机一字排开,待命起飞。

22时整,该团团长王天林和大队长王辉领受任务后,一前一后跨进战机。“10秒,5秒,1秒,起飞!”战鹰如离弦之箭,即刻消失在茫茫海天中,一场实战背景下的夜间空舰导弹攻击演练拉开了序幕。

某海域,空中战鹰盘旋往复,海面舰艇来回穿梭,气氛格外紧张。突然,王辉通过显示屏发现了目标,立即向前舱报告:“目标出现!”王天林闻讯,迅速驾机向 “敌”舰艇编队靠拢。一个奇特的信号一闪,机载电子设备顿时失灵,“敌”舰正在对我机进行电磁干扰。王天林沉着果断地指令后舱:“启动机载电子对抗系统对 ‘敌’舰进行有源干扰。”

“明白!”王辉熟练地输入程序,我机凭借先进的电子对抗系统对“敌”舰进行电磁攻击,同时以最短的时间过滤杂波,很快消除了“敌”舰的电磁干扰,通信和雷达设备恢复正常。

然而,正在我机即将对“敌”展开攻击之时,“敌”舰又一次对我机实施更加强烈的电磁信号干扰,并企图歼灭我机。“镇定,启动应急预案,转换大功率!”后舱的王辉心领神会,轻击按钮发出一道道程序指令……

时间一秒一秒地过去,海天之间弥漫着战斗的气息。王天林加大油门,以超低空方式进入“敌”电磁干扰盲区。

“发现目标!”王辉报告指挥塔台。“调整最佳射程范围,咬住对方!”指挥员命令。我方抓住有利战机,以一个漂亮的左右大角度迂回,绕到“敌”舰侧面,用先进的机载火控系统迅速锁定目标。

“目标锁定,请求攻击!”王天林报告。“攻击!”王天林迅速按下发射按钮,两枚模拟导弹呼啸而出,划破漆黑的夜空,“敌”舰被命中。

指挥员点评

■北航某团团长王天林

千里之行 始于足下

当前,航空兵部队开展复杂电磁环境下训练比较困难。我们的体会是,在复杂电磁环境下训练的初级阶段,只有从电子对抗训练切入,才能逐渐深化对复杂电磁环境下作战规律的认识,进而总结规律,创造条件,使复杂电磁环境下的训练真正成为常态训练。因此,我们在训练中不是另起炉灶,另搞一套,而是按照“缺什么、补什么,什么弱、训什么”的原则,从一个个基础课目做起。这正如行军一样,千里之行,始于足下。
basically, it talks about JH-7A using active ECM in ASuW missions. It talks about the ship using its ESM/ECM against the JH-7A, which then also its EW suite against the ship using active jamming. Talks about going to the blind area of the opponent's ECM by flying super low and then finding the target and hitting it.

Re: JH-7/JH-7A Thread

this is kind of interesting, it talks about the anti-shipping for JH-7A and importance of having Change II, a LORAN-C navigation system, as the basis of PLANAF sea faring basis. You may not be able to find the target ship even if the navigation system is one second off.
HBAO这么说我就不藏着了

飞豹制海,前提是对海上情报搜集能力有足够的信心。本朝在上世纪最后10年获得来自西方某国的技术支持,建立了“长河2号”罗兰C远海导航体系,基本确立了本朝航空制海的基础。

千万不要小看导航问题,岸上引导出击,哪怕差1秒的精度,飞出去很可能就找不到目标。在解决了海上自身和对方舰艇的定位问题后,对于飞豹这样反舰平台的需求就会吃果果的提出来了。

另外还有一点 要说,来自毛国的技术同样关键,否则大型对海监视的雷达统统搞不定。当然,我们以前也有一些,效能差点。不过考虑到飞豹的大航程,没有更远的观测能力,等于浪费了。好在,我们在90年代中期获得了飞豹作战体系所需要的所有主要设备。

飞豹对反舰的战法,很机密。本官就小泻一点,大家自己眼盘。CD有的是飞豹的飞官,咱就不显摆丢人了

2战以来的航空搜索办法就这么几个,飞3角形 四边形 五边形。貌似没有看到飞六边形的,螺旋线的 有,苜蓿叶型也有,貌似和反舰没啥关系。咱们这里就说反舰的

飞三角形的经典,我记得应该是中途岛战役期间的利根号上那水上飞机。这种飞法,搜索速度快,但是搜索区域小。原因为啥,自己画图算下面积就明白了

四边形五边形肯定要范围大一些。这里具体就不说如何操作了,因为HBAO肯定揣着砖头说,你丫说这个和飞豹有啥关系?等等很快就要有关系了

Re: JH-7/JH-7A Thread

Hi guys … I once again need Your help; this time regarding the equipment of the JH-7 Block 02.

I try – similar to the J-10 – to put them into the correct context:
As far as I know these are the real first serial machines as all older machines – namely if not officially JH-7 Block 01 – were regarded as prototypes:

081 (1. prototype)
082 (static airframe)
083 (demo ac)
084 (said to be lost)
085
810 (sometimes said to be a JH-7A but on the picture available clearly an early bird (maybe Block 02 ???)

The following machines were regarded as pre-serials for the first PLA-NA regiment 6th Ground Attack Division - 16th Regiment - JH7 (81x6x) in Shanghai-Dachang equipped with the original Type 232H 'Eagle-Eye' radar

Then the Block 02 followed for a second regiment within the 6th Ground Attack Division - 17th Regiment - JH7-02 (82x6x) in Yiwu

… and here’s my question: these Block 02 machines were said to be equipped with the additional Spey 202 engines obtained via GB and as their most important change with the new JL-10A radar


But why do they still have the same old “greenish” radome like the original machines and not the black radome as the later JH-7A’s ????


Thanks in advance, Deino :confused:

Re: JH-7/JH-7A Thread

083 was the first to test the JL-10A radar and it had the greenish nose too. I think 084 is still around. 811, 812, 813 and 814 I think are JH-7A prototypes.

The black radome was mandated later, and first identified with the use of the KLJ radars on the J-8. However, the JL-10A is made by a different firm from the KLJ series. The company that made the JL-10A is also the same company that made the JL-7 or Type 222 including variants like the JL-7A and JL-7AG for the J-7 variants; the Type 232 on the JH-7; the Type 204, 204A and 208 of the J-8II. As noted, all the noses of the planes were all green. They said to change the radar on the J-7G to the KLJ-6E, but the cone is still green.

The black noses on the serial JH-7As prompted some rumor that the radar on the JH-7A has changed from the JL-10A series to another member of the KLJ series. Can't fully discount this which is why someday I like to see a picture of a black nosed JH-7A with the cone opened.

Re: JH-7/JH-7A Thread

Sorry for posting it here too but as here are some guys around which are not posting at CDF ... :eek:


Can anyone help me out with some specific details on the WS-9 and esp. the Quinling !

As far as I know is the WS-9 a licensed “copy” of the original Rolls-Royce RB.168 Mk.202 Spey obtained during the mid to late 1970s to power the JH-7and replace their originally planned WS-6.

For the JH-7A later an improved version called Quinling – and IMO strangely not called WS-9A – was developed. Certification was granted in July 2003 and production is running since 2004. It was officially confirmed in a TV-report in January 2008.


What I need or want to know is:
1. Has anyone some additional technical data like thrust, weight, … for both engines ?
2. Just to name them correct: WS-9 = Spey 202-copy !! Quinling = improved WS-9 but not called WS-9A ?? ... or WS-9 = Quinling ???
3. Are there any information about the technical changes made from WS-9 to Quinling ?
4. Are there some more dates to add into the timeline esp. for the Quinling ?


And there's another mystery to me: Some sources say the development was – as expected – heavily delayed by problems with production and only the Quinling was the final originally anticipated Spey-copy. Other sources – and here also the Rolls-Royce Heritage Trust – say that around 300-400 engines of the standard WS-9 were already built up to large stocks, at a time when only few JH-7 actually flew.

So, for what ??? Was the live-time of these engines too short ?? Was there another project anticipated for them which finally failed ?

Thanks a lot in advance,

Deino :confused:

Deino :confused:
i just know that the production certification didn't happen until last year. I suppose that's the version that had all the small issues sorted out, but the service life is probably still less than that of Spey. I'm not sure about the T/W ratio though.
