IAF team flies Gripen Demo in Sweden with operational AESA radar

21 Apr 2010


One of the few benefits of the ongoing flight ban over parts of Europe meant that 8ak got extra time when we caught up with Eddy de la Motte, Director India for Gripen (Saab). Mr Motte confirmed that India had sent an IAF team to Sweden 2 weeks ago and flew the Gripen Demo making it the only foreign air force to have flown the advanced version of Saab's Gripen Demonstrator. IAF pilots did about 10 flights in Linkoping. Mr Motte said that in mid-May 2010 the Gripen Demonstrator will be sent to India and confirmed that the Gripen Demo was flown with a fully operational AESA radar developed jointly by Selex and Saab Microwave (Formerly Ericsson Microwave).


There was some controversy last month when the FMV (Swedish Defence Materiel Administration) blocked Saab from sending the Gripen Demo fighter to India on the basis that the only plane was needed by the Swedish Air Force for further testing. The RFP for the MMRCA states that the plane offered in response to the tender should be the one that is used for trials but as per Ajai Shukla, the IAF+MoD will give Saab some leeway in this. While this may cause the competitors to cry foul, it is a good sign that the IAF+MoD are using their discretion, where allowed, to assist them selecting the best fighter and this could work to advantage of others as well. For example, Eurofighter, for one is hoping that the dreaded 'L1' (lowest bidder) clause would not be the deciding factor where multiple fighters qualify in the final round.

To clarify, Saab's Gripen aircraft has 4 versions from A to D, then comes the Gripen Demo which is a demonstrator aircraft (and hence different to Gripen D) for the next generation version planned for India interchangeably called the Gripen NG or IN.

To date, Saab has conducted about 20 flights in India, mostly in Bangalore's Aircraft Systems & Testing Establishment (ASTE) where 2 Gripen-D fighters did low-level, high-speed supersonic tests. In Jaisalmer the 2 aircraft did a weapons release test and one aircraft sent to Leh did landing, engine cold start and take off with full internal fuel plus 2.6 tonnes external load.

Manu Sood, Editor, 8ak mentioned that the American components in the Gripen, mainly the GE F414 engine, is viewed by India as its biggest drawback. Motte said that if that was a genuine concern, then India would not have bought the P-8i and C-130-J aircraft which will play a crucial role in future conflicts and the IAF would not have considered the two U.S. fighters in the MMRCA competition nor the same GE F414 engine for its Tejas LCA which is now in the final stages of a race between that and the Eurojet 200.

Asked what he thinks is Saab’s strongest point, he said "Gripen is the only option that will make India completely independent of the need to purchase combat aircraft from other countries. Gripen IN is equipped with futuristic warfare technologies developed specifically for India and a perfect match to the IAF". He further mentioned that the low operational cost will translate in to more training hours and he believes Saab is the only company to not only offer a complete ToT on the source codes of the AESA radar (though Russia has promised something similar) but also joint development.

Saab did not comment on the issue of revising the bid price. Earlier AviationWeek had reported that since the commercial bids were valid for 2 years ending Apr 28, 2010, this meant that the vendors could now revise their commercial bids. Given the worsening economic situation globally and huge competitive pressure on this large and geo-politically important deal, surprisingly it means that the bids would be revised downwards! However, a person familiar with defence acquisition told 8ak that "sometimes a simple procedure like collecting certificates from vendors saying we are ready to give the same price also fulfils the need".==================================

Selex and Saab Microwave

联合搞的AESA
三弟不一定能看的上
瑞典要是又搞出丝带那就喜感了。。。。
欧洲要不联合的话   4代估计出不来了

反正法国人是在自己搞隐身无人机了。
等法国搞出来再说吧   TG也在搞
图呢????????????
SELEX是很有竞争力的
下一个十年的欧洲机载雷达市场,统治地位吧
话说SELEX和SAAB现在应该都算英国人的企业了~
看不懂 LZ翻一下

    Selex 什么时候变成被英国人收购了?

意大利人怎么搞的。
没有爱立信的MMIC也是比较难搞的。

BAE貌似也有一个子公司搞MMIC的
爱立信的死对头不是华为吗?
不得不说斜盘结构是个不错的点子。[:a2:]



有利于散热
不错

    是一種在成本和探測距離上的折衷產物,比起昂貴的側面陣列是實在多了
gsx56840 发表于 2010-4-24 23:27


非常适合现役战机的现代化改装

不过我觉得可能更适合那些雷达罩和基座是近似圆形截面的机种,像是viper系估计就不太行了
侧向斜装比向上斜装好?

不光是斜向安装

关键是基座可以旋转,可以保留传统机械扫描结构在某些模式和水平搜索角度速率上的优势。



至于LO性能,阵面转到斜向上就可以了。



当然缺点就是重量以及增加了机械可靠性的问题。

不觉得有多高明,要说能动毛子Su-35BM不比这个玩得还高明么?

解决电扫角度问题的正确做法是宙斯盾那样——每一面都装上收发单元,而不是现在这样学机扫,这样付出的代价挺大的 :shutup:
有了转动部件, 不知道增加多少重量
旋转基座‘、可动主动阵这种方式虽然可行,但感觉是混合态;
多面阵“正统”多了,虽然成本、空间等问题目前难以解决。
pzgr43 发表于 2010-4-25 07:37

阵面固定在旋转基座上还是要比毛子那种万向支架可靠多了。

结构相当于一个水平放置的单面阵MESAR/SAMPSON.

而且RAF认为毛子的那种转得也不够快。


多面阵目前对战斗机来说来说实在太贵了。
觉得弄个机械转动结构也不错。
阿三不买了就给发财装个
三锅威武,不一定要的
瑞典自己的空军用了么?A3想当小白鼠?
果然是人傻钱多的三哥啊......
很无聊的想法~~~
单轴旋转增加不了多少重量
新一代战机都用相控阵
瑞典要是又搞出丝带
哪有这么多个“又”??
还是蛮羡慕印度的国际关系

要是我们也象阿三那样只用不仿不看不学,买零部件买50年。。。  估计我们哈都可以买到。。。
看着学、看着学30年,也似30年。
