It would appear that everyone is an expert on the topic of IAF’s acquisition… except for the incompetent IAF. 😉
Nick, don’t worry about it. You can lead a horse to water but you can’t make it drink. If people choose to ignore the reams of information on the Tejas’ capabilities and the IAF’s and HAL’s commitment to it, then there’s nothing you or anyone else can do to change their mind. So, don’t worry, have curry. 😀 Save your energy for people who genuinely care for information not the internet flotsam that wash into the thread once in a while.
BTW, shifting the topic to AI07, anything in particular you are looking forward to?
I am hoping more info, especially a model of the CAT would be shown. Also, hoping for a more than just a half-assed LCH model. Any news on the IJT-Al-55I integration?
Is the Gripen supposed to do a display?
Harry, you gonna do a pictorial special on this AI for ACIG, like you did in the past?
For the record, Vick and I are not related. 😀
On a cheerful note, ISRO just now successfully launched four sats on the PSLV platform.
I believe the weight on the LCA is on the low side. Yet, I would support your numbers as a whole…………..Sorry, I took so long I was no the phone to MOM.:D
The Tejas’ weights are from the design agency, so the chance of a discrepancy is low, not impossible but low.
I wouldn’t be suprised if the wiki article on the J-10 is “massaged” a little bit in the future, now that the spec numbers aren’t working out. 😀
Needless to say, I will keep an eye on the J-10 wiki entry to see if any massaging of the numbers is done 😉
China has come along way with the J-10. Yet, she needs to move on to exercises with other nation like India is doing right now! As for J-10 and LCA comparisons. Well, the information available is so undependable its hard to have a far debate. Yet, as I have stated over and over the J-10 is in service and the LCA is not……..and after 25 years that says alot!:rolleyes:
Is that the sound of back peddling I hear?
After being so sure that the IN20 outputs 18 klb, there was a mighty climb down from the perch after showing the manufacturer’s press release.
Now you were so sure that the J-10 has better TWR than the Tejas, it’s become “the information available is so undependable its hard to have a far [sic] debate”. But you were so sure that the J-10 has a better TWR than the Tejas, even with the undependable data. Now that the data shows something that you don’t believe, the data becomes “undependable”. LOL
Ok, raise of hands, who here didn’t see that “undependable data” comment coming? :rolleyes:
Like I said before, think of all the things that you are sure about. You were very sure about the IN20 and the TWR. :diablo:
So, Scooter, what do your sources have to say about the TWR of the J-10 and Tejas? I’m still waiting… :diablo:
What are your sources and can we consider them reliable? :rolleyes:
For the J-10, I used wiki. Infallable? Not. Within the ballpark? Probably. But if you can come up with a source that is definitive or at least more credible, I am very open and will modify the numbers accordingly.
For Tejas, I used ada.gov.in
Now, show me yours… 😉 :diablo:
Which, sources are we going to use yours or mine?:p
You use yours and I’ll use mine and then we can compare.
Here’s what I have come up with:
J-10
MTOW: 40,600 lb
Empty Weight: 21,500 lb
Max Thrust (Al-31FN): 27,600 lb
TWR: Min – .68
Max – 1.28
Tejas
MTOW: 27,500 lb
Empty Weight: 12,100 lb
Max Thrust (IN20): 19,000 lb
TWR: Min – .69
Max – 1.57
Well, lookie here! Looks like the LCA can maintain equal or higher TWR compared to the J-10, through out its loading envelope. 🙂
You were saying something about J-10 having a higher TWR? 😮
Well, I am gald you are so good at Goolge! I check “quickly” and the source I read quoted 17,700 lbs and just over 18,000 lbs. Further, both said the Indian F-404 was bascially a F-404-GE-402. Which, by the way does make the same power and is the last F-404 in production for later model F/A-18C Hornets. Regardless, it appears your information is correct. Next time I will search a little deeper. That said, in my defense your 19,000 lbs really doesn’t do you much good as the J-10 Flanker powerplant still makes over 27,500 lbs plus and clearly provide a high thrust to weight ratio than your LCA. Also, as it has been said over and over again your LCA is not in full scale prodution or squadron service. So, the point is really moot or at least at this stage…………:p
Quick, think fast: What’s the MTOW of the J-10 and the Tejas?
For Scooter’s benefit, since he seems to have missed it the first time, I will repost a previous post in its entirety. 😀
I don’t believe the Mirage 2000 is marketly superior to the J-10 because it has a Superior Airframe and comparable Avionic/Weapons. Further, the J-10 will also have better thrust to weight ratio. By the way the production engine for early LCA is the F-404-GE-IN20. Which makes something around 17,700 lbs (possibly 18,097) and is very similar to the F-404-GE-402 in later F/A-18C’s. This occured because of the continued problems with the Kaveri GTX-35VS. Last I heard India was looking to outside engine manufactures for help and it doesn’t look like it will enter service anytime soon if ever……..
Again, speaking of facts: F404-IN20
India LCA: F404-IN20 validation testing is nearing completion with initial deliveries of production engines for the India Light Combat Aircraft (Tejas) program scheduled for mid 2006. Testing has included installed performance/operability, plus validation of control schedules and mechanical systems. The engine has generated more than 19,000 pounds (85 kN) thrust during the program. Indian defense officials have ordered 17 engines to power initial Tejas production aircraft and have expressed interest in procuring an additional 20 aircraft, with options for 20 more.
Come on now, it took me, according to Google, 0.38 seconds to find this article. Do some fact checking on your own before spouting things. Now think about it, if you were wrong on something so basic and easily accessible as this, makes you kinda wonder what else you might be wrong about and you don’t even know that you are wrong.
I bet that, before I pointed this article to you, you were absolutely sure that the F404-IN20 produced 18 klb of thrust. Think of all the other things that you are sure about… :diablo:
You should talk about “delusions”! The LCA hasn’t even entered service yet and is not likely to for many years to come if ever? All the while the J-10 is entering squadron service with the PLAAF in large numbers!
Maybe the PLAAF has lower standards? Doesn’t the PLAAF have Mig-19 variants flying around still? :diablo:
Further, the engine in the LCA program has been a total failure and India has had to go back to the US for the less powerful F-404 to make do! Regardless, both types have foreign engines and radar…………So, I lack to see India’s superiority? As both countries have access to similar technology from many of the same sources!
There you go again, spouting stuff you have no idea of what you’re talking about.
You don’t need three different types to have three lines. Instead more than one production line can be used to produce any of above mentioned types…to increase production rate.
Sure, there are multiple permutations of how the IAF can get aircraft but the fact is that they chose this way. I am sure that they used more than just internet aviation enthusiasts, like me 😉 , to come up with their acquisition plans. Of course, throw in some politics and policy changes and we have the delays that we see now in the MMRCA.
The LCA program seems to be going fine now. Within a span of 5-6 years of first flight, five prototypes are flying, while a confirmed order for 28 are being built with another 20 on options. The plane is slated to reach IOC in late ’08 through mid ’09 and FOC around ’12.
Kaveri’s shedule will not affect the Tejas’ shedule as the two programs have effectively been delinked or put in another way: The Kaveri will be “plug-n-play” once it’s finished, till then IN20s.

Since people have been talking about LCA, i’ll move away from the on going question and ask a real question.
We expect RFPs to be issued soon for MMRCA, and unless im mistaken Gripen is believed to be one of the contenders??? Since most here believe LCA to be in Gripen class, and if so, would HAL also receive an RFP for LCA???
The point is to have a parallel acquisition path to the LCA so that three production lines (MKI, MMRCA, LCA) are churning out planes faster than the IAF is retiring them. 100+ Mig-21/23/27 and Jags are on their way to reaching the end of their technical lives in a few short years.
