Dear Prasun sir,

Feedback:

+ve: Excellent blog, excellent coverage, keep up the good work

-ve: Please change the skin. White on black = hard to read.

I would also like to have your take on rarely heard projects like the BHIM artillery and INSAS guns.

Regards.

Deeply appreciate your feedback. Will try level best to maintain the standards and will come up with new insights on the status of the weapon systems you've highlighted. Rock on!

Sid said...

nice, you do have your hands full with latest in defense circles.

keep it up.

Prasun K Sengupta said...

Thanks Sid. Next month's going to be busy as I will be going to the defence and aerospace expos in China, Indonesia & Pakistan. Got lotta things to write about.

Sid said...

great...

so you will be at Pakistani IDES. wonder how they allowed you in.

try to get some in depth info on their much touted UAV and artillery programs.

that country is getting too much tech from Turkey and China which India should be aware of.

you should open a website prasun, for the stuff you publish you shd be rewarded. i had a friend who had a website on the motorcycle trend in india and he used to make $100/month within the first 3 months. considering the traffic to yours you should be making much more. since this is a tiring job considering you write hellava lot and answer ppls comments / questions pls consider this option. ofcourse it has to be a free site that is paid thru ads.

how does this radar matches the russian ZHUK AE35 for mig 35 offered to india cuz both seems to b same size

but the price U CAN HAVE 2 ZHUKAE35 FOR THE ONE RBE2 AESA

and zhuk ae35 has the same performance as of rbe2 aesa

just like r77 performs superior to MICA and costs only half the price

Prasun K Sengupta said...

The Zhuk-AE till now is just a laboratory prototype and has not yet been certified for series-production. Some more fine-tuning has to be done, especially its MTBF which according to the Zhuk-AE poster I posted before, its 500 hours, which is way too low. It should be a minimum of 1,000 hours, especially since the figures quoted by rivals like RBE-2, Seaspray 7000e & APG-79 are upwards of 5,000 hours. However, in terms f modes of operation and mission effectiveness, all current-generation AESAs (Russian, European and US) offer similar and appreciable capabilities, and it is up to the end-user to optimize them via network-centricity. The sky's the limit as far as such innovative concepts can be conceived and applied.

in fact all europea and russian aesa radars r in developing phase
and probably b operational in 2011

only US has operational AESA

but by the time v start inducting MRCA both euro and russky AESA will b in production

To Sid: My visit to the IDEAS expo will be brief for only 3 days but I will be seeing the very same exhibits that they show in other expos in Turkey, Indonesia, Malaysia, etc. Therefore, for me personally, there's no great surprises as such. But I always enjoy visiting the Chinese aerospace and defence expos as there are always some new products displayed there. But as you are aware, India's armed forces and intelligence agencies are Pakistan-centric till this day, and are not according China the attention it truly deserves.

-------------------------------------------------
from where did u get this 5000 hours MTBF IT seems to b unreal

form air power australia

it says MTBF for APG79 MTBF is
917hours

Phazotron marketing material puts the figure at a respectable 900 hr MTBF which compares closely to the 917 hr MTBF of the more complex US APG-79 AESA. This may reflect yet again the Russian propensity to overdesign components, which in a thermally challenged design amounts to using devices well below their maximum power ratings.

Prasun K Sengupta said...

Both the MTBF figures quoted by the Australian magazine are 'the achieved to date' figures based on laboratory tests and the limited flight tests to date of the Zhuk-AE and APG-79. The figures you quoted for the Zhuk-AE are the desired levels, not achieved levels and that's why the figure quoted by Phazotron in its poster, prepared last December, still mentions 500 hours. The figure of 5,000 hours is given by US and European manufacturers as being the figure when it is time to remove all the AESA LRUs for routine servicing. Until then, the AESAs can still operate without any performance degradation. It means if even there are some premature component failures within the AESA, it does not automatically translate into complete non-performance of the radar. The key to maintaining the optimum performance of AESAs is not just the reliability of the radar itself, but the reliability and design of the aircraft's environment control system (ECS), which ensures the maintenance of the AESA's operating temperature within specified safety levels.

---------------------------------------------
same thing russian designers has said about the zhuk ae that even if its some t/r modules gets too hot those particler t/r modules r automatically shut down untill they cool down and inspite of this radar works perfectly and whole radar doesn't become unoprational like earlier pulse doppler radars

which makes radar to avoid t/r module failure and saves cost cuz t/r modules r too costly

atleast its good that rafale doesn't show it in indian colours

but just c gripen

Anonymous said...

no one buying rafale its bloody costly and its armament is costly
su30 and its varients r hottest selling fighters and before sukhoi mig was the hottest fighter selling russian company

To dd7: Many thanks for your well-meaning suggestions. But yaar, money was not the motivation factor for me starting this blog. If folks like you regularly visit this blog and engage in discussions concerning the contents of this blog and if such engagements enable you all to develop a better, discerning appreciation of national/regional security matters then I shall consider it as Mission Accomplished. Until then, rock on!

by the way the top most pic is of production radar or prototype radar ,and if its a production radar how many t/r modules it has

Anonymous said...

to prasun

what is the power per module and what is the peak power of rbe2 aesa

zhuk ae has 5watt per module and
6kw for the radar

Thanks this is pretty usefull. Could u please tell me the estimated number of T/R modules the RBE-2 AESA radar boasts of? Yet again thanks.
