OT :

In IT, it is applied, where 80% of SAP project are either considered failure or non starters. And professionals called PMPs are employed to produce garbage in form of xls and mpp.

Drishyaman

Still better would have been to realize all this before starting the project, minimize the risks and go for a twin engined Kaveri @ 65 kN. Shaurya Ji, Last heard Kaveri was generating a thrust of 72 - 75 kN. And ADA is already having a project with twin Kaveri and they are calling it AMCA :wink:

Drishyaman

So, many different types of system integration need to be done before FOC for Tejas.
Just wondering, if the deadline would be enough for the same ?
Can someone put some light ?
I am not trying to be pessimistic here.

Rahul Ji, Thank you for the explanation on Jaguar upgrade, I have been following BR for last 10 yrs. My knowledge about aeronautics in nill ;). I am sure you will understand short comings. (I had actually packed up my books on mechanical some 11 yrs back and after that I did my pg on a different sub...

drishyaman there may be some improvement in top speed, but not much at the high end of the envelope as they said, might be better performance at ingress and exit speeds increased thrust will help in climb and turn, but no extrapolation was made - what painstakingly explained to you was that an a2a ...

Drishyaman

drishyaman ji, you are coming across as confrontational which I'm sure is not your intention. singha ji's assessment is correct on every count, btw. No Rahul Ji, I am not trying to be confrontational. I am just putting my views :) Let me explain to you what is in the back of my mind (May be I am wr...

Nowhere, I mentioned Mach 2

Where did you get that number for Jaguar ?

Drishyaman

regardless of thrust the airframe shape and structure puts a limit on top speed and agility. so Mach1.6 at high alt may well remain the top speed. more important will be its medium alt escape speed and low alt ingress speed increase if any. the Jag is not a agile plane....in a IAF demo I have seen ...

Drishyaman

If F125IN is selected, the maximum thrust of Jaguar will become 88 kN and 250 kg reduction of weight of the Jaguar (as per wiki) empty weight will become 6750 kg. As of now Jaguar has 65 kN thrust with 7000 kg empty weight and its Maximum Speed is 1.6 Mach. What would be the possible Maximum speed o...

I have yet to come across a strong business reason why NAL/HAL would like to build a 70-100 seater , what kind of market they are focusing at and what is the sales projection and revenue generation expected for NCA. So, India should never attempt a civil aircraft after all? There were similar quest...

i am very surprised with this argument. firstly TSP never \had more than 52 teens. They could not afford more. Till 2005 all they had was only F-16A/B s with no BVRAAM. Its passe to blame unkil for everything but he could have given AMRAAMs in 1996 to TSP. he didnt. we all can keep arguing but as e...

Drishyaman

great. i meant that US fighters were much superior to Soviet fighters from 1960 onwards. That is your partisan view. See, I told you above you are partsan ;) Both F-16's disengaged because they didnt have BVR missiles during kargil. So, you mean to say 2, F- 16 ran away seeing a Mig in layman’s lan...

and in case PAF managed to have 200 of them.. we would have ceded some of our territory as well.

Drishyaman

my views are very very simple. these birds had double the range of our soviet birds, they were more serviceable and 52 of them were enough to deter us when they were operational. the jags with the asm had a range of 300 nm while the teens had a range of 520 nm. it makes operational planning very ve...

Why ? Could you please, give the argument in favour of your favourite F - 16? That is, why not anyone from the other 5?

The first prototype demonstration of Ajun Mark II will take place by June 2011. By 2013-14, the first batch of about 30 tanks will roll out of the HVF, said Sivakumar.

Dear All, I am currently reading "Disciple", authored by Stephen Coonts. He mentions a unique system called "ALQ-199" that makes US Navy's Hornets invisible to the Iranian radars. I just want to ask some Gurus whether this system really exists or it is a mere imagination of the ...

A request to Negi ji and Gurneesh ji, both of you have done a good job in listing the questions on Arjun and Tin Can.
Can you also, provide the answers along with the questions ( I know answers has already been provided

) then people might not ask the same questions again ?

when we can think of an LCA Mk3 twin engined with a home grown AESA radar , ECM and stores. 5 years down the line, it would be a win-win. “LCA Mk3 twin engined”. This suggestion comes up every 2 – 3 month. Quoting Rahul M from “Design your own fighter” thread moreover, if you try to design a twin e...

MMRCA deal is nothing but a stop gap solution for filling up the depleting force. If any TOT happens along with that, it will be icing on the cake. If, there is going to be any TOT it has to be cutting edge otherwise it will be meaning less and I have a big doubt about the TOT happening. So, I guess...

I believe most of us are thinking why IAF is not keen on Tejas project instead of going ahead with MRCA project. Yes If IAF invest the money into development of Tejas it can have a decent fighter for next generation. Supporting a home grown fighter is more important than supporting somebodies econo...

Tejas MK – II will be lengthened by 0.5 meter just behind the cockpit. Is that being done to accommodate more of the delta wing within “Mach” cone? Can this be assumed as a drag reduction measure?

With the kind of delay happening in deciding MMRCA for IAF, deciding which one to pick up is becoming a complex decision with time. Now the buzz is that the decision has been deferred to 2012.
