LCA news and discussion

Postby narayana » 03 Mar 2009 11:50

Please stay on topic.

That means :
a> No comparison with aircraft A,B or C.
b> No half-baked suggestions to improve LCA like "add a laser gun"/"merge DRDO with ISRO " etc etc.
c> NO whining.

Rahul.

46 test flights in the month of february me thinks it included sorties of Aero India

Put it in the LCA folder. We don't need to look two folders up just to follow LCA...

Ah.. But I think, after Aero-India there is a lot of good info in the old thread and a cleanup of that thread would make more sense rather than starting a new one.

But then I am not admin..

My apologies to the Admin for the arguments that ended the previous thread.

regarding the post on AeroIndia increasing the LCA sortie count, I don't think that they were validating/testing anything during any of the AeroIndia flights, so it only increases the hours, but not the flight test status.

and one more point- K Prasad (or Rakall?) said that the LCA had been tested to an AoA of 21 degrees..a report from 2005 , by Air Marshal P. Rajkumar, said that it had already been tested to 23 deg AoA..so they probably haven't crossed that as yet due to uncertainties of high AoA flight testing.

If we go by P Rama Rao committee, I think everything is not going well for LCA. See the report here

http://www.indianexpress.com/news/what- ... e/429935/1

The fighter may even miss the revised deadline of December 2010 by “one-two years” as DRDO has not been able to generate enough test flights. The present fighter fails to meet requirements set by the Air Force in 1985.

^^ I would take those reports with a pinch of salt. Even the snippet you quote says the LCA does not meet specs from 1985!! I am very sure there were a lot more requirements after that. Go through the LCA threads and you will find a lot of discussion on this.

The LCA probably meets all specs that it was designed for - i.e. to replace Mig-21s. It can probably do more than the Mig-21 presently.

ASR has changed quite a lot since those days, major part of the increased weight is due to that.

On the contrary - it is doing better than expected. Clock technology is being used to increase the stealth of the LCA so that it will remain undiscovered for even longer.

More seriously, it would worry me a great deal if the LCA in 2010 met the 1985 ASR.

is it cloak technology(making object invisible) or clock technology?

wot happened to the cockpit stealth?

DRDO came up with the technology a way back.Are they integrating the same onto LCA?

Although this has been discussed in almost every discussion forum on internet related to defense; but ASR is a top secret document and has never been made public to any journalists.

A lot of journalists have written about changing ASR by IAF.

Seeing the track record of Indian Defense Journalists; I always had a hard time believing this.

IMHO DRDO is plagued by over confidence and delusional thought process.

The utter lack of accountability. Clear cut time bound goals must be defined and people overseeing the projects must be held responsible and fired if they are unable to deliver. Private partnerships must be sought for mass productions.

I know this is not really related to LCA; but I felt this was relevant here.

^^ My friend, if the ASR is indeed top-secret then you dont know whether it changed right? In spite of that you are ready to accept the DDM opinion of DRDO being overconfident etc. Please do not malign them any further based on assumptions.

Besides if what you say is right, the IAF is sticking to their requirements from 1985 which have not been met! That's 24 years! :shock: The IAF would have to be really stupid to not have changed their requirements considering the changes in military aviation in these 2 decades!

well, I was trying to point out the time line not the ASR. All we understand that it was changed several times.

Crupt Politition are behind to kill and delay the LCA.If we do select LCA for MRCA,It is hard work and R/D then politition will not get the kickback.

Both can be used.

Cloak technology is still being developed, but clock technology is already proven and was used to keep the LCA invisible for 20 years. It can be used again to delay the induction by another 2-3 years.

Looks like some kind of icon must be used for sarcasm :wink:

Posted in the previous thread,thet the delay in flight testing was supposedly resolved with the Europeans getting the contract,so that the schedule could be met.This was from AWST,etc.The contract was at the last stage before signing said one report.

This is regarding the express article , i remember one or two years back, express came out with a series of article inditing DRDO on LCA , AKASH ARJUN, just when these projects were turning a corner in the labs. I can say so cause thats what subsequently happened
Now all these products have actually been ordered to be inducted in the respective services, and LCA was the pride of Aero India09
yet the article can make an immediate sceptic out of a laymen
Even USA had to develop many tranches or blocks of fighters liKE f-16
And F-15 to realise their full potential, I guess the writer of the article
wants all blocks of F-16 like development to Happen at once with the LCA
and he does not spell out the "5" grave shortcomings
I thought engine and radar were the only grave "Shortcomings"
but thats just 2 , i guess i'll have to revisit my counting skills

I agree this article in IE is written by a joker who I suspect is paid to denounce indigenous R&D. Such jokers should never be given the due respect of link from the BR front page. :evil:

DRDO Press Release.

"The second phase of weapon testing on Tejas is currently underway from an Air Force base in the north-western sector. The focus of the current phase of testing is safe separation and also accuracy of weapon delivery. The results from the tests would validate aerodynamic interference data as well as complex weapon release algorithms in different modes of release.
A Composite test team comprising of specialists from ADA, IAF, HAL, NAL, ADE, DGAQA and CEMILAC had been put in place at the trial location where the flight test is being conducted by National Flight Test Centre.

"Arrangements are in place for directly linking the trial location with the base telemetry station at Bangalore via INSAT and also through a secluded fiber optic channel. With this arrangement, designers and other specialists are able to monitor in realtime, the activities in general and vital parameters in particular, as the trial is going on thousands of kilometers away. Specifically for this trial, accurate upper air data is gathered at the trial location using GPS Radiosonde supplied by ISRO.

"The mood at ADA and other organizations involved in the trial is upbeat as the information has just come in, that Tejas has scored a direct hit on the target in the first test sortie itself. The trials are planned for two weeks’ duration."

wouldn't INSAT SATCOM Link be vulnerable to interception?

Have you heard of cryptographic communication sir ?

Even if they intercept it they need to make sense out of it to be useful

What is this cloak technology? Many people are talking about it. Can it be used to build better cloak rooms for the Indian Railways? Clock technology must be the time warp project that will make the LCA a potent weapons platform in the 1965 war. Jagan will have to re-write his book. That clock project is headed by Manikavachagam Pillai.

Holeee! where are these bums being bummed? Also, what kind of range does this indicate on the itty bitty Tejas? IIRC, IFR has not yet been done. After doing all the weight reduction etc, etc, 3000km ferry on internal fuel looks within realm of possibility. Thats MKI range! I'll be blowed.

it could just have flown to Nagpur, and from there, have flown to the test range in Rajasthan, or could have staged somewhere in Rajasthan as well..maybe they didn't set up a telemetry station there, unlike when they went for cold weather testing at Leh.
