三哥的LCA要改装俄国的RD93发动机？

难道这就是爆菊？

Hmm… An interesting development. Indeed, I have already said about this possibility in my blog early. I think, the allegedly selling of an uprated RD-93 engine to China and the current Indian tops' activity around RD-33MK for India are two related events. Indeed, many years (more than 5) Russia repeatedly refused to sell the RD variant with increased thrust to China. One cause for this – is Indian pressure and the agreement between two nations for not allowing China have more advanced weapons than India. The second – Russia by self doesn't want China to be too assertive, so the weapons sold for China were always inferior in some degree relative to what Moscow sells to Delhi.

But the technological development is continuing. Sometimes you must run for keeping your place. Russia cannot refuse to sell 9 t RD-93 engine for China infinitely (till now it sold only 8.3 t thrust variant). It because the China copy WS-13 (with 7.8 t thrust) is gradually improved and becoming close in its characteristics to the regular RD-93. If Russia refuses now it will lose both the market and the leverage on China. So, the refusing loses its sense.

It's not a secret, that India wants its Tejas light fighter will be more advanced than the Chinese fighter FC-1 (JF-17) of the same weight class. This advantage has not only a military but political and psychology aspect too. One of the most important and persuasive characteristic of a fighter is its engine. According to its thrust, reliability, service life can be made the conclusions about capability of the aircraft to take weapons and fight.

Thus, the current Indian preoccupation in seeking a more powerful engine for its indigenous Tejas project is well understood against the background of aggressive Chinese FC-1 marketing to India's neighbors. A more powerful engine with longer life could help Tejas mk.2 to take-off the carrier deck, keep more payload and be more maneuverable in dogfight. Now installed GE F-404 engine isn't powerful enough, and the development of the indigenous Kaveri engine is too slow.

Till now two foreign engines were evaluated by India as candidates for Tejas mk.2: the European 90 kN EJ200 (EF-2000) and the American 98 kN GE F-414 (Super-Hornet). Only F-414 gives Tejas a decisive advantage over FC-1's RD-93 in thrust, although being slightly heavier. An airframe (inlets) rework is needed too. 90 kN EJ200 has no significant advantage over RD-93 especially if it is going to be uprated to 9 t = 88.2 kN. Furthermore, since the uprated variant of RD-93 is based on RD-33MK technologies, it must have service life close to 4.000 h. Whilst EJ200 according to some sources has only 2000 h life.

The Chinese were not allowed to produce RD-93, but they bought a repairing facility and technologies for repair. Thus they are unable to make a new RD-93 but theoretically still can try to 'overclock' RD-93 for even more thrust - 90-93 kN – however with expense of reducing life in some degree. In such a way they can have an engine with better than EJ200 tech characteristics for half a price. It can be the critical point for their FC-1 program export success. If they indeed, as was reported, are going to buy up to 500-1000 RD-93 engines with increased power, they are very serious in this aspect.

As a 'hermeneutic' analysis can say us, the Indians tops could be now with the dilemma (or trilemma):

1) Going for the American 98 kN F-414 . Proved risk to be sanctioned in most unpredictable and hard situation. A totally new engine in IAF and IN inventory. However, could have some sense if F/A-18 wins MMRCA tender. Growing friction with US on nuclear issue makes this choice too risky and so – improbable.
2) 90 kN EJ200 – doesn't give any tech advantage for Tejas against it's main competitor and rival. According to my estimation could be as twice more costly than RD-33MK-based engine if recount to lifespan. Theoretically can be sanctioned by each participant of this project (GB, Germany, Italy). Significantly reduces the export prospective of Tejas.
3) RD-33MK variant with the bottom gear placement and a thrust vectoring nozzle (RD-133). Can be uprated up to 10 t (98 kN) thrust in near future without changing the engine core. The Russian obligation to not sell TVN for China can be obtained, so the advantage of Tejas mk.2 engine (if chosen) can be visible and persuasive for public. The KLIVT all aspect TVN can be especially worth for the carrier based Tejas' variant now actively developed by HAL. The 8.3 t RD-33 ser.3 variant of the engine is already licensioned and ToTed in India, so only a minimal addition will be needed for RD-33MK production in India.

PS I'll put this evaluaton in my blog too…

但奇怪的是三哥居然对这样的“一日三变”可能带来的工程滞后一点都不担心，反而对中国很有优越感：”俄国人好东西只会卖给我们，绝不卖给中国”

{:3_94:}阿三学会了商业操作中的包库存？！！

嘿嘿  把RD93清完库存JF-17就飞不起来了吧--某阿三将领如是琢磨

是三锅放了美帝鸽子吧

那LCA推力岂不是更不足了···

三哥的牛皮吹上天的卡维力呢？

到了2010年。三哥又看上MD 的。再换。

Kavery 的研发似乎已经停止

表这里笑三锅了，我们的不太行搞定了没？

不是说要换F414或者EJ200的吗？怎么又看上了RD93这垃圾？

上面链接是三哥们论坛中的Kavery发动机专栏，要了解三哥发动机进展的可是进去逛逛。

Kavery发动机问题还很多，推力不足，超重，单晶叶片材料不过关.......似乎印度空军也对Kavery发动机的研制也失去了信心.......它已经成了了一僵尸工程

3) RD-33MK variant with the bottom gear placement and a thrust vectoring nozzle (RD-133). Can be uprated up to 10 t (98 kN) thrust in near future without changing the engine core.

RD-33改啊，改出来没有呢

嗯...一个有趣的发展。事实上，我已经说过了，在我的博客最早可能。我认为，据称一个大功率的销售的RD - 93引擎，中国和周围路目前的'印度上衣活动对印度33MK是两个相关的事件。事实上，许多年（5个以上），俄罗斯一再拒绝出售的增加推力中国路变种。这样做的一个原因-是印度的压力，以及两国之间不容许中国比印度先进武器的协议。第二-自律，俄罗斯不希望中国过于自信，所以对中国出售武器总是不如在一定程度上相对，莫斯科卖给印度。

但技术的发展正在继续进行。有时候，你必须运行保持你的位置。俄罗斯不能拒绝出售9吨的RD - 93发动机为中国无限（至今，仅售出八点三吨推力变量）。这是因为中国的副本的WS - 13（与七点八吨推力）正在逐步改善，成为其特征接近正常的RD - 93。现在，如果俄罗斯拒绝，将失去市场和对中国的影响力。因此，拒绝失去其意义。

这不是一个秘密，说，印度希望其特加斯轻型战斗机将超过中国战机先进的FC - 1（架JF - 17）同一量级。这种优势不仅是军事而是政治和心理方面的了。对一个战士最重要和最有说服力的特点之一是它的发动机。根据它的推力，可靠性，使用寿命可对飞机的能力的结论，采取的武器和战斗。

因此，目前在寻求其土著特加斯项目，一个更强大的引擎，印度的当务之急是充分理解反对侵略中国足球俱乐部的背景1营销到印度的邻国。阿寿命更长更强大的引擎，可以帮助特加斯mk.2到起飞的航母的甲板，使更多的有效载荷和更加混战机动性。现在安装了通用电气的F - 404发动机是不够强大，以及土著卡佛里发动机的发展过于缓慢。

截至目前两名外国引擎的评审工作由印度作为特加斯mk.2候选人：欧洲90千牛EJ200表（EF - 2000）和美国通用电气公司98千牛顿的F - 414（超黄蜂）。只有架F - 414给特加斯决定性的优势通过FC - 1的RD - 93的推力，虽然略重。一个机体（口）也需要返工。 90千牛EJ200拥有路没有多大的好处，93特别是如果将是大功率的，以9吨= 88.2千牛。此外，由于路大功率的变种，是基于93的RD - 33MK技术，它必须服务寿命接近每小时4.000虽然EJ200据一些消息来源只有2000小时的使用寿命。

中方不允许生产的RD - 93，但他们买了修理修理设施和技术。因此，他们不能作出新的RD - 93，但理论上仍可以尝试'超频'的RD -更大推力为93但与降低生活费用- 90-93牛顿-在某种程度上。以这种方式，他们可以有更好的一半以上EJ200价格高科技特色的引擎。它可以为他们的光纤通道临界点- 1计划出口的成功。如果他们真的，因为据报道，将要购买多达500-1000的RD - 93发动机功率增加，他们在这方面非常严重。

作为一个'解释学的分析，我们可以说，印第安人的顶部可能是现在的困境（或三难选择）：

1）美国98千牛的F - 414走向。探明受到制裁的风险，在最不可测的和硬的情况。印度空军的一个全新的引擎和库存。不过，可以从某种意义上说，如果F/A-18大胜利MMRCA招标。成长与美国在核问题上的摩擦使这种选择太冒险了，所以-不可能的。
2）90千牛EJ200 -不给出反对的特加斯任何技术优势的主要竞争对手和竞争对手。据我估计可能会更昂贵的两倍以上的RD - 33MK型发动机的寿命，如果重新计票。理论上可以由每个批准该项目的参与者（英国，德国，意大利）。大大减少了出口的Tejas前景。
3）的RD - 33MK与底部的齿轮安置和推力矢量喷管（的RD - 133）的变体。可大功率的可达10吨（98千牛顿）在不久的将来在不改变发动机的核心要旨。俄罗斯有义务对中国不出售可TVN，因此利用mk.2的Tejas引擎（如果选择），可明显和公共说服力。所有方面的KLIVT可以TVN特别是对承运人的价值基础特加斯'现在变HAL的积极发展。在八点三吨的RD - 33发动机ser.3的变种已经licensioned和印度长颈，所以只有增加最小号将需要- 33MK在印度生产。

PS我会放在我的博客evaluaton太...

14# seaharrier

改到10吨级.............还没看到........就是最近的总设计师专访（9.25号）也没提......所以觉得怪.......

貌似9吨是目前的东西〉。。。。。。。。。。。

我不得不佩服三哥的地勤。。。。是在是太天顶星了。。。三哥满赛。。。

大能的三锅，别弄10架有3种发动机就好

为啥不用米国的？

试验机好像就是米国的，咋又换毛子货呢？不解

日程安排就是超级虫子最先试

接下来10份（？）是米格35..............其实阿三早就去毛子那里试飞了...............（是否等着上1088 T/R 的AESA）

接下来是欧洲列国....................( 欧洲列国基本把握不大。。。。。。）

HKC多就有这个好处。

F404不要,要RD93,三哥真是有个性啊

三锅很有喜感
但是各位童子也该省美疲劳了吧...
