Re: China Su-30 thread

let me see if I can translate this
  作为俄罗斯空军持续现代化计划的一部分,苏霍伊设计局选择了KnAAPO(阿穆尔共青城飞机生产联合体)作为其苏-27侧卫战斗机一系列升级计划的主承包商。这种被称为Su-27SM的升级型号在很大程度上是基于中国订购的双座Su-30MKK多用途战斗机的基础上的(76架Su-30MKK已于2000至2003年间交付中国)。
sukhoi chose knaapo's design as the upgrade package, calling is su-27sm, many of the upgrades are based on su-30mkk
  编号38-02,“56”的Su-27SM的原形机本是一架近期生产型飞机,隶属第60战斗机团,驻扎在靠近共青城的Dzemgi,于2002年12月27日在当地进行了首飞。根据合同,KnAAPO将对更多的飞机进行现代化改装,按计划首批接受改装的4架飞机中的3架将于2003年年底前完成改装。
su-27sm first flew in Dec 2007, knaapo modified for su-27s by 2003
  就在首架Su-27SM试飞后不久,一种出口升级演示机的细节被披露了出来。该机使用原Su-27SK 40-42号的机体,序列号36911040102,建造于1998年。该机侧面编号“305”,本来计划于6月进行的2003年巴黎航展上露面,然而该计划在航展开幕前几天取消,原因是担心飞机被瑞士贸易公司Noga由于债务纠纷而采取强行法律行动而扣押。随后,Su-27SM于8月在莫斯科举行的MAKS2003国际航空航天展上首次亮相。
also, after su-27sm flied, the Russians also flew an upgrade package for su-27sk, these were disaplyed in MAKS2003

  在众多的升级改进中有一项是由Ramenskoye PKB负责对座仓进行了彻底的重新设计,安装了3个液晶显示器??两个MFI-9型 7英寸*5英寸显示器以及一个夹在在两者之间的、较小的显示器。与Su-30MKK的前座仓不同,Su-27SM保留的模拟式仪表仅仅是作为备用的,而前者仍将其作为主要飞行仪表使用。Su-27SM的其他改进包括一个新的Elektroavtomatika SILS-27平显,在导航组件中新增了A737全球定位系统以及一套新的通信设备。
3 MFDs, 2 7x5 inch MFD and a really small MFD. different from su-30mkk's front cockpit, su-27sk only use analog meter? as a backup, whereas mkk uses it primarily su-27's upgrade also include SILS-27 HUD and navigation added A737 GPS and a new set of communication system
  在实际运作上,最有潜力的改进将是对雷达系统的改进。代号“熊猫计划”,Aerokosmicheskoye Oborudowaniye 和它的下属研究院Tikhomirov NIIP正在改进Su-27的N001雷达。这项计划被分为两部分:改进它的空对空性能以及加强其对目标的探测、跟踪及打击能力。最终的结果是客户将会有一系列雷达型号可供选择,以适应各自不同的需求、进度表和经济承受能力。
most important is the panda radar upgrade package. changes to the A2A functionality, it's up to the requirement of the customers
  被称为NOO1V的完全升级型号是供俄罗斯空军使用的,具有使用R-77M主动中距弹同时与2个目标接战的能力。雷达的运算能力显著提高从而使探测距离从现在的43-54海里(80-100公里)提高到73-81海里(135-150公里)。它还将提供目标识别、在集群目标中锁定单一目标以及探测诸如直升机一类的慢速飞行目标的能力。使用空对地模式,N001V具有地图测绘和动目标鉴别指示的功能。跟踪距离测试按计划将于2003年年底完成。
N-001V is used by RuAF. able to engage 2 targets with R-77M. The radar increased search range from 80-100 to 135-150 km.
  由于雷达新的Ts100计算机系统具有共享高速数据传输线路,并使用C和C++高级语言编程,因此仅需3-4架次的测试飞行进行试验。考虑到传统上飞行测试占用了高达80%的研发经费,用于验证N001V新功能的少数几次试飞无疑节省了大量资金。

  对N001V雷达的进一步发展按计划将在今年实施,力争在每个俄罗斯空军的飞行中队至少配备1到2架飞机。新雷达将安装称为Pero(羽毛)的相控阵天线,具有同时跟踪15个目标、同时接战8个目标的能力,并将显著提高对目标的跟踪距离。由于配备了TKS-2(R098)加密数据链,多达16架的Su-27战斗机能被整合成一个集群使用。Pero雷达能使长机在较远的距离上跟踪较多的目标,并把目标信息传递给其他战斗机,从而使它们能隐蔽接敌。
talks about pero, can track 15 targets and engage 8 at once with improvement in detection range. Uses TKS-2 datalink, can link up to 16 su-27.
  新增武器

  在Su-27SM上引入N001V/VEP雷达和光电跟踪系统将赋予俄罗斯空军现役Su-27机队不具备的空对地精确打击能力。尤其是Su-27将能使用Kh-31A超音速反舰导弹和远程(130公里)的Kh-35U亚音速反舰导弹。新雷达还能从动于诸如Kh-29T、Kh-29TE、KAB-500Kr、KAB-1500Kr之类的电视制导导弹和电视制导炸弹的寻的头,并能保证在夜间和恶劣天气下的精确轰炸。
new weapons include kh-31, kh-35u, kh-29t, kh-29TE, kab-500kr, kab-1500kr
  此外,Su-27SM还能携带电视导引的Kh-59M导弹及其增程型号--285公里射程、主动雷达导引的Kh-59MK型别。新增的L150 Pastel电子侦察系统和Kh-31P反辐射导弹配合,将赋予Su-27SM战斗机全新的SEAD(防空火力压制)能力。
also kh-59m tv guided missile and kh-59mk
  作为升级计划的一部分,机体结构将得到加强从而使最大起飞重量增加到30450公斤。(俄罗斯空军现役Su-27战斗机的最大起飞重量是28300公斤,但1992年后制造的出口型号的此项数据已经达到了30450公斤)由于俄罗斯空军没有相应要求,空中受油能力将仅供出口型号选用。
maximum liftoff increased to 30450 kg
   在两个计划中,Salut在MAKS 2003航展上展示了部分细节,因此计划的目标相对明确。该现代化改进计划被分为3个阶段,最初分别被命名为AL-31F-M1、M2和M3。后来为避免侵犯NPO土星集团的知识产权,Salut删去了“AL-31”前缀。
salyut unveiled AL-31F-M1, M2, M3
  接受了第一阶段升级的发动机在Su-27 37-11“595”号飞机上进行了飞行测试。首飞时间是2003年1月25日,此后又进行了20次试飞,用于研究在飞行包线内某些关键点处的发动机稳定性。第一阶段的升级项目包括安装一个新的增大直径KND-924-4型低压压气机(KND为低压压气机的俄文缩写,924为直径尺寸,毫米,4为4级)和SAU-235数字式控制系统。

  Sault宣称新控制系统的可靠性是旧系统的3倍而重量却节省了40公斤。新压气机使最大非加力推力由75.21千牛提高到了81.49千牛,最大加力推力则由122.58千牛提高到了129.80千牛。然而发动机的重量也由1547公斤微增至1557公斤。

  在第二阶段现代化改进期间,新的涡轮盘冷却系统将被采用,因此能把加力推力进一步提高到138.26千牛。在今年将实施的第三阶段,将采用一个全新的、具有3级宽弦叶片的风扇(低压压气机 )。这种名为KND-924-3的风扇采用整体式叶片盘技术,与老的4级风扇相比具有更大的增压比和更高的效率。一个KND-924-3型风扇已于MAKS 2003航展上作了首次公开展示。如果将其运用到现有发动机上,将能把加力推力提高到143.17千牛。
MMPP Salut的新压气机与旧型号的性能比较:?
  标准压气机 KND-924-4 KND-924-3
  压气机级数 4 4 3
  直径 905毫米 924毫米 924毫米
  增压比(H=0,M=0) 3.55 3.67 4.2

  Salut的AL-31F发动机升级计划是自筹资金进行的,而NPO土星集团却得到了苏霍伊设计局和俄罗斯空军的支持。NPO土星计划安装一个新的涡轮,这将能使效率由现有的0.86-0.87提高到0.92-0.93。有两种方案供选择:一是提高加力推力15%至140千牛,或者是通过降低涡轮进口温度110度从而增加2.5倍的使用寿命。

  在茹科夫斯基展示的另一项有关Su-27动力装置的改进是矢量喷管。这种被称为“Klivt”的喷管是由Salut和克里莫夫设计局共同研发的并已经被安装于Su-27 “595”号机。该喷管具有16度的半锥型(三元)偏转范围。相比之下,Su-30MKI装备的AL-31FP发动机仅具有偏转范围+/-15度的二元矢量喷管。对该喷管的飞行测试尚未开始,但至今已进行了400小时左右的静态测试。
spends a lot of time talking about the upgrade in engine and how it's done

  Su-30KN

  尽管伊尔库茨克工厂和其自己的设计局Russkaya Avionika提出的Su-30KN升级计划已被俄罗斯空军否决,但研发工作仍在继续。功能上,Su-30KN和Su-27SM非常相似,两者现有火控系统的算法和软件都被保留,新增功能由添加的新的软硬件实现。Su-30KN与Su-27SM的主要区别在于:在Su-27SM上,NIIP使用由Korund制造的Baget-54计算机,而在Su-30KN上,Russkaya Avionika整合了自行设计的MVK计算机。在操作上,NIIP的雷达系统具有增强了的抗干扰性能上的优势。
IAPO's su-30kn is similar to su-27sm
  虽然Russkaya Avionika正在促销其雷达系统用于Su-30战斗机,其主要的兴趣却在于发展供别里也夫 别-200水陆两栖飞机所使用的雷达。

  俄罗斯空军和海军现在拥有约400架Su-27,制造于1985至1992年年间。对于机队中机龄最短的飞机的改进将首先进行,然后才是较老的飞机,直至资金耗尽为止。计划的全部细节至今未知,一些报道声称全部Su-27机队将获改进,另一些报道相信现有资金仅供升级20%-25%的飞机。
russia has 400 su-27, but probably only has money to upgrade 20-25% of them
 
  下一步如何?

  Su-27的现代化改进计划是与俄罗斯空军下一代战斗机苏霍伊T-50战斗机的发展并行的。虽然T-50的机体将于2006至2007年完成,但其新发动机、航电设备和武器系统在2012至2015年之前是不可能完成研制的。这样,T-50最初将使用完全升级的AL-31F发动机和为Su-27SM发展的航电设备进行试飞。据推测,侧卫系列战斗机将在俄罗斯空军中继续服役到至少2022年(甚至极有有可能至2032年),这意味着未来将有更多的针对SU-27的升级计划,这对保持其战斗力和完整性是十分必要的。
what's next step? T-50 is the next step.


that's pretty much it. As for why China is not buying more su-30. It's because China realized su-30 isn't worth the money.

f they won't buy it, are they will built like J-11 A, under the designation as JH-8?

Re: China Su-30 thread

Unlikely. J-11A is a fighter, but we are certain that the J-11B is coming out. Since Fighters and strike planes have merged much together these days under the name fighter, you can pretty much forget the name JH-8, thought it can be used as a strike plane.

Re: China Su-30 thread

well, we might as well treat this as the flanker thread.
This is from the latest kanwa issue.
reporting a new division in lanzhou and the new engine purchases.

I'm not convinced that those new engines are for J-11B. I personally think they are for upgrading su-30mkk and old su-27 since their original engines should be nearing the end of their service time by now, but that's just my opinion. Yeah I know the Russians promise a lot, but their service time never reach what they said.

Re: China Su-30 thread

Russia does supply alot and I mean alot of military equpment to China. Could Russia keep up their promises I do not know. But from my side, engines are a easier product to import. I think it could very well be for J11B. From my knowledge arnt J-11s now also armed with rocket pods for ground attacks? Correct me if Im wrong.

Re: China Su-30 thread

The su-27s were armed with rocket pods a long time ago. They used them in the 1996 excercises, to conduct very outdated unguided ground attacks. Even helicopters can use rocket pods more effectively.

typhuang, I doubt that the r-77 can fire 100km, but 50 is too short. 50km is the range of the AMRAAM and the Derby. The r-77 is bigger than the Amraam, and has a very powerful motor. The missle travels slowly for a A2A missle(mach 3), all of which add up to the conclusion that the r-77 must have a longer range, probably 75km. Of course, you never fire your missle at maximum range.

actually, the maximum range of R-77 is probably 100KM (so, it can theoretically go that far), but that's not the maximum effective range of R-77.

I guess it depends on what profile you are measuring the range under. Different profiles, different range.

Anyway, having looked over the article and examined it more carefully, the stuff about Lanzhou getting a new regiment is just junk. Seriously, the photos for the 19th division
Please, Log in or Register to view URLs content!

clearly shows that the flankers with serial number 30106 and 30107 are for this division. Not the 37th or 47th division as mentionned by Kanwa. This is getting sad. Their analysis is based on the flankers' background.

Hm, well, i recently compared few missiles, got as much info bout their test firings as i could and tried to extrapolate some results, depending on their size, weight (minus warhead), speed. It does assume engine/fuel is of same efficiency in every missile - which might be wrong.

I concluded max range for mica is just under 70 km, for r77 is just under 100km, for aim120c7 is just over 80 km. That is, of course, max theoretical range in perfect conditions - highest speed at launch, highest altitude, stationary target not evading, etc. Anyone care to agree or disagree?

Ive heard way to many figures fo the aim-120C7 to be sure. i ve heard 60km, 80-100km, and even as daring as 150 km.

Btw, the r-77 is not the PLAAFs longest ranging active seeker missle. The r-27AE has a range of 130km, the longest ive seen for a MRAAM.
