I dont have any thing aganist BDians.

That guy was saying something like cow piss drinkers and all..Then I posted Chies eating rats,pigs and all kind of stuff.

I have also shown them what their cooking oil is made of from dead animals and pigs fat.

That chine troll couldn't answer.
this is not chit chat thread.we can talk there.

Re: Why is Indian Airforce is not accepting Tejas mk1 completely ?

Okay... I have n verification of it apart from the article u mentioned If it is fake oKay....

Both Pogosyan and the Russian ambassador pointed out that the information was fake in official disclosures.

DRDO is given a job of preparing war machines It there there job to understand how wars are won.....

No. They are expected to make something according to requirements within the timeframe agreed upon. Once they exceed the deadline, the armed forces can change requirements to keep its capabilities relevant. And the armed forces aren't stupid enough to make unreasonable demands.

DRDO doesn't know anything about how a war is fought or won. Think about it. They are just scientists, they have never studied anything about war. From day one to the time of college they receive the same education as everyone else. After that they do masters and PhD that has nothing to do with real warfighting. They are merely learning how to build and employ technology. They are just given some specifications and they build according to that.

Ok agreed DRDO didnt but does that give us liberty of not relying on DRDO anymore?

Yes. And it was exercised. That's how IAF got the MRCA tender started.

One thing I know maintenance of both will be in India by Indians only as rafale will be definately costly

Who cares? Rafale can do stuff that LCA cannot even think of. Imagine the difference between a Maruti 800 and a BMW M3. That's roughly what LCA is and what Rafale is.

That also means we have limitation on funds

Depletion of yearly budget is a very good sign. It doesn't mean there were limitations on funds. It means the armed forces bought all they could for the year. The armed forces will always ask for more and there is no such thing as enough money in their dictionary.

Any funding limitations will not affect capital purchases.

AMCA and FGFA are they gonna deliver in time?

I don't know about AMCA, but PAKFA is within schedule and is undergoing acceptance trial. Assembly line was ready last year. It is possible production has already begun because the aircraft is soon to be inducted and first squadron operational in 2016.

IN has been fully in sink with DRDO on this .... really happy

Depends. IN is taking delivery of 45 Mig-29s and will soon release a tender for Rafale, Super Hornet and possibly the F-35. Right now, they want LCAs, but are in double mind because of the slow progress on LCA Mk2. Even ADA is going carefully with LCA since they have ordered only 8 F-414 engines out of the 99 contracted.

If they were going not to rely on TEJAS for future of IAF why they didnt scrap it earlier?????...

They wanted the aircraft. That's why it wasn't scraped. It won't be scraped now either because the requirement is still there for 6 squadrons. As long as we have Jaguar we need aircraft like LCA to provide escort. Once Jaguar is gone, LCA will completely lose most of its relevance, but it will still be flown until the end of its life. We are yet to see if LCA will undergo MLUs or simply be scrapped at a future date.

All other aircraft will escort themselves.

AMCA and FGFA are still only on paper or developing are u sure DRDO will deliver this time...

As mentioned earlier, it is too early to speak about AMCA. DRDO has nothing to do with FGFA. FGFA is HAL and Sukhoi's project.

Tejas mk1 u dont treat as fighter ... by the time MK2 gets out will yo treat it as fighter?

It depends on the tactical relevance of the aircraft. For eg: MKI and Rafale completely beat the LCA in every single flight parameter. FGFA and AMCA are bound to do better. LCA is no better than Mirage-2000 or F-16, both of which are obsolete today. We can somehow manage to keep some of the electronics updated, but performancewise, it is obsolete today even in the Mk2 form.

If you will and even with the induction scenario will it not be preferrable to induct atleast 2 more squad of tejas ?

An optional order for 2 more squadrons is possible, but LCA Mk1 has little or no chance.

IAF is planning to induct all the modern toys how are they planning to maintain them?

By building factories, warehouses and service depots in the country.

I have full faith in IAF but the only thing i am raising is why are u giving false hopes .....????
If you dont want it tell it upfront......

Who's giving false hopes to who? Time you come back to reality and accept the fact that LCA is too late or do you simply want me to tell you that the LCA is the best of the best and that IAF is too foolish to buy it or do you want the truth?

What you want to believe is up to you.

If you have full faith in the IAF, then let them do as they please. As far as I can see, they are making the right decisions.

 

[laughingbuddha]

Escorting the jaguar: perhaps the mk2 with better combat range. The mk1 doesn't even qualify with its puny combat range. They're good for lingering around the border, forget escorting the jags in strike missions.

Its been a great learning experience with Tejas, period. They will be inducted in limited numbers.
let us hope DRDO/HAL put the invaluable knowledge gained from Tejas into developing a world beating AMCA.

 

[p2prada]

Mig-21 had lesser range and used to provide escort to the same Jaguars. LCA can do that as well, but it has shitty acceleration compared to the Mig-21.

 

[Kunal Biswas]

Jaguare are more for SEAD operations, In today`s day Multi-roles dominate Air-forces of the World ..

Why would need Jaguare for strike when Tejas are more than enough for such mission, But again ..

Deep penetration now belong to cruise missiles, India is investing more on such technology ..

Re: Why is Indian Airforce is not accepting Tejas mk1 completely ?

hye
I am not a expert in the field of aero but luckily being a mech engg I am working in it....
the news you shared about This F-15 landed with just one wing.
Is technical not possible saying this after consulting few of my leads but the only possibility that would have been is that the damage might have happened at a very low height and at very less speed... by less I mean quite low....

just from my own personal experience .... I can say that the after the wing being damaged there is not much scope of controlling the aircraft
As i can see in the image posted we can assume that Aileron was damaged along with many other parts including Clips , stablizers and barckets providing stability to the wings and connecting it with the frame and stringer of the fuselage region .
So there is no way the aircraft would have turned ,changed direction or even to an extent changed altitude.

I am no expert to judge or challenge that news as miracles happen and sometime luck do shine.....

But one case like that does not give me enough reason to trust that nor does it define its ability to take a hit ....

Both Pogosyan and the Russian ambassador pointed out that the information was fake in official disclosures.

Mig-21 had lesser range and used to provide escort to the same Jaguars. LCA can do that as well, but it has shitty acceleration compared to the Mig-21.

Do you even know what is the Thrust to weight ratio of Mig-21 and tejas before talking about which has shitty acceleration?

http://defenceforumindia.com/forum/...-combat-aircraft-technology-evolution-10.html

educate yourself in the above link.

The specs of Mig-21 bisons,

Empty weight: 5,339 kg (11,770 lb)
Gross weight: 8,725 kg (19,235 lb)
Powerplant: 1 × Tumanskiy R25-300, 40.21 kN (9,040 lbf) thrust dry, 69.62 kN (15,650 lbf) with afterburner each.

The specs of Tejas,

Empty weight: 6,500 kg (14,300 lb)
Loaded weight: 9,500 kg (20,944 lb)
Max. takeoff weight: 13,300 kg (29,100 lb)
Powerplant: 1 × F404-GE-IN20 turbofan
Dry thrust: 53.9 kN[93] (12,100 lbf)
Thrust with afterburner: 85 kN[94][95][96] (19,000 lbf)

For a gross weight of 8725 Kg Mig-21 bison has a thrust of 69 tons a TWR of 0.79 ,

For a gross weight of 9.5 tons it with 85 Kn engines tejas has a thrust to weight ratio of 0.89,

how much will the emergency bump thrust increase this low TWR with how much weapon weight for how long. Not worth comparing with Tejas mk-1,

And what is the duration of the emrgenct bump thrust in Mig-21.

let us hope DRDO/HAL put the invaluable knowledge gained from Tejas into developing a world beating AMCA.

hot climate has its own debilitating effect on combat ranges, So it is not accurate to compare the range of tejas with western and russian fighters whose figures are generally for a lower temp than tejas operating environment in india's hot climate.

So fuel fraction which gives a much better idea about combat range is given below.

The fuel fraction which determines the effective combat range with useful weapon load (opposed to misleading ferry range given by the makers as PR effort)is given below,

Su-30MK: 34.9%（Empty weight: 17,700 kg，Internal fuel: 9,500 kg）

Rafale: 31.4% ~ 33.6%（Empty weight: 9,500 ~ 10,220 kg，Internal fuel: 4,680 ~ 4,800 kg）

JAS-39NG: 30.6%（Empty weight: 7,100 kg，Internal fuel: 3,130 kg）

MIG-35: 28.6%（Empty weight: 12,000 kg，Internal fuel: 4,800 kg）

Tejas: 27.0%（Empty weight: 6,500 kg，Internal fuel: 2,400 kg）

JF-17: 26.3%（Empty weight: 6,450 kg，Internal fuel: 2,300 kg）

JAS-39C: 25.0%（Empty weight: 6,800 kg，Internal fuel: 2,268 kg）

This is a fair comparison of fuel fractions with just internal fuel , and the same percentage will more or less reflect with external fuels also,

So Tejas mk-1(which still has 400 KG of flight test equipment on board, removal of them will lead to even better fuel fraction) itself has much better fuel fractions than grippen C/D with more TW ratio and lower wing loading,

Tejas mk-2 will easily compare to RAFALE which has just 4 percent more in fuel fractions than Tejas mk-1.

So in indian conditions there won't be any issues with range of tejas mk-1 or mk-2 in useful combat configuration if we take into account that four tejas can be operated for one RAFALE if we include total lifecycle costs and upgrade costs,

So there is no way Tejas can be faulted on weapon load or range.

Re: Why is Indian Airforce is not accepting Tejas mk1 completely ?

Both our 5th Gen plans appear to be in trouble or at least are not on time ie delayed so soon even they will be obsolete just referring to ur comment on tejas regarding this ....

No. There doesn't seem to be a problem with the 5th gen projects. AMCA isn't delayed either. 2020 is a good date to see it flying. PAKFA is already undergoing acceptance tests.

The engine promised on FGFA by Russians to IAF hasnot even entered bench trials. IAF is very disappointed with it, That is why they cancelled the double seater portion of 60 plus FGFA instead of converting them to additional single seater.

They will be obsolete 20 years after induction. LCA is obsolete today because induction times are the same as that of FGFA. Actually, Rafale was supposed to be inducted fully before LCA Mk2 even started production. And Rafale is far better already.

LCA Obsolete? Then all other fighters other than 5th gen are obsolete by the same standards!!!!

As per group captain and test pilot Suneet krishna's words tejas in mk-1 version itself is "at least equivalent to upgraded Mirage-2000 for which IAf is paying close to 1.5 times the price of new tejas mk-1"

Cost matters. But if you throw around a figure like $35 Billion, then it becomes meaningless because even the F-22 does not cost so much.



It wasn't the delay which increased costs, it was just a very bad estimate by the govt and was completely unrealistic, and that's why they removed it.

How can you justify introducing both the 5th gen F-35 and 4.5 the gen RAFALE almost at the same cost?

The first squadron should be inducted by 2018. Contract is already done, they are working on lifecycle costs before it goes to the MoF. Once the approval process begins, it may take 3 to 6 months, basically a done deal, just have to wait for the bureaucratic procedure to be completed. That's why the tentative date today is the end of the year, basically 7 months away from May when the new govt comes to power.

Contract is not signed , only evaluation is finished.The UPA in its final days has refused the french request for a guarantee on the deal, You must have known that

Relying on the F-35's engine is different from the maintenance PoV compared to "being shot by the enemy and engine goes kaput" PoV. The Mig-27 in Kargil crashed because of a faulty engine, the Mig-21 received a small warhead in the tailpipe and was shot down. These were our two losses during the war. A Rafale would have likely survived both. LCA, neither.

Hit on one engine will cause a fire which makes having another engine no plus point in combat time. May be when one engine fails your analogy is correct. To survive just one such hit rafale costs four times tejas. if it is so why did french build single engined mirage in the first place?

That's the thing. We don't have that other plane "there only". Did you forget that IAF has a limit to how many aircraft they can own? 42 squadrons is the limit.

So what is wise. accepting sq limit and spending more money or increasing sq limit while spending less?

If we have 126 Rafales, all can be used on any of our borders. We will need 250 LCAs to get that same coverage, but we will still have lesser range and will need expensive tankers to make up the difference. But IAF can't have 250 LCAs because they are only allowed to buy 126 LCAs.

One tejas can refuel another , we don't ned tankers always, Don't you know that? Defence min Antony has gone on record that tejas can easily replace all the 400 Mig fighters in IAF. Haven't you read that?

We can't have a greater force because getting that greater force needs govt approval and we are still one decade away from the govt actually deciding on increasing numbers. It may come after 2030.

Govt approval will be given if IAF gives the reason. Govt will be delighted to have more squadrons at a lesser cost than buying an expensive lesser no of fighters that cost a bomb in buying and another bomb in uograding and maintaining over decades!!!!

It is an underpowered bus. Nothing to do with trust. It simply failed to meet basic requirements.

Refer the previous post of mine. Even now after Mig-29 and Su-30 tejas is the better TWR fighter than all other migs and mirages(even after upgrades!!!) In mk-2 it will come closer to Rafale TWR also.
It has alower wing loading than Rafale which has its own plus while maneuvering.

That's just silly. You are confusing good maintenance with cheap maintenance. Mig-21s had cheap maintenance. Guess what happened.

Mig-21

Maintenance costs do matter, but if I give you a salary of 1L a month and you live like a guy earning 5000, then you are doing things all wrong. You don't go to Ratan Tata and say he should use Nano simply because it is cheap. That's how you are arguing. IAF is allowed to buy Rafale because they can afford it, along with MKI, FGFA and AMCA. If given a chance, they will dump LCA altogether and induct more Rafales or FGFAs.



The F-22 and F-35's problems are very different. F-22 was cut short as a program. What was a 1000 aircraft program became a 187 aircraft program. That's a recipe to disaster. It's like you make food for 1000 people and only 100 show up. That's what happened. The F-35 was constrained by severe design restrictions because of the STOVL requirements. AMCA and FGFA are constrained by neither of these issues.

IAF has never had a solid base, but has always flown the best aircraft available.

So you should stop postin stuff that is not correct.

Luck... perhaps. But you don't deserve to call yourself an engineer for using the word "miracle." Things don't get explained away just because you add miracle next to it.

As MDD explained, it was a combination of very high TWR and body lift design.

But one case like that does not give me enough reason to trust that nor does it define its ability to take a hit ....

That was an effing mid air collision. Only large aircraft have survived such collisions. It took a much greater hit than a missile could manage. It appears you will now suggest LCA can take much more damage than a heavier twin engine aircraft can.

This is a UAV flying after loss of a wing.

A very very important read. He is of our own ilk so it becomes far more important to understand why we need twin engine fighters.
Twin Engine - ...But What About Stealth & Survivability? - SP's Aviation
Some important quotes from the article.

During peace time, birds have destroyed so many single engine fighters and killed pilots in vulnerable states of flight that the threat cannot be overstated.

Therefore, both propositions—of near perfect reliability of modern jet engines as well as survivability rates of single and twin engine fighters being comparable—are myths.

And guess what, we are mostly only inducting twin engine aircraft. That's proof enough to show what we really want.

So, I have one question for you. Is LCA a twin engine aircraft? No. Does the IAF have any "real" need for it? No. Can the IAF make do with LCA? Yes. Can IAF afford more expensive twin engined aircraft? Apparently, yes. So, what's your real problem here?

If your only support to induct LCA is its cheap cost, then that is not a reason IAF is really interested in. All the European and American cost cutting articles are forcing their way into the Indian mindset only because LCA is supposed to be cheap and affordable, which doesn't exactly concern the IAF as much as you think. IAF is looking for high capability at reasonable costs, not low capability at throwaway prices. So, your concern for affordability is something else entirely, like asking Ratan Tata to drive a Nano.

If LCA had capabilities the Rafale has today, like carrying 9 tons (with 4.5 tons of weapons) of payload up to 1800 Km away, then things would have been different. However, as it stands today, LCA doesn't conform to modern definitions (4.5th gen) of multriole aircraft. It is in effect a single role aircraft with multiple capabilities, almost exactly like the Mig-21. Meaning, it cannot exercise multiple capabilities in the same flight like Rafale or other 4.5th gen aircraft can (including Gripen NG and J-10B). Its only other equivalent cousin is the JF-17.

Don't forget that India is currently in an arms race, the west is not. Indigenous weapons don't win wars, good weapons win wars, history attests to this fact.

 

[p2prada]

@Pulkit

A pretty good example of the importance of twin engines as advertised by a pan-European/American consortium.
Survivability - The AAS-72X+

Survivability begins with a twin-engine aircraft that can lose an engine to enemy fire and still get crews back to base, even in high/hot conditions.

This is so damn important for our requirements.

Re: Why is Indian Airforce is not accepting Tejas mk1 completely ?

sir
thanks for the insight on the all the facts u have put infront of me ,

yes I am an engg who believes in luck and miracles just a request dont make it personal ...

I have enuf experience to take a call at that .... why i know that even with a difference of one degree the condition within the aircraft changes ...
I never challenged what u stated but presented a small info regarding the same if thats what u dont agree you have ur own views .....
If the material used to create a very small part is not as per standards its a issue.... if a part have a small scratch or flaking or even delamination its a issue.... if there is a difference in the shifting of ailrones its a huge issue.....

Body lift design hmmmm it could have helped agreed but...

at subsonic speed I just dont wanna think abt the friction it would have caused ... I seriously dont know if it was damaged what force helped it fly engines might be ... but then direction ... oh with one wing....but that cant perform alone ...

Also the weight of the aircraft could have given it stability at a very high speed but any tearing on the wing would have been fatal....

Sir

I am not trying to prove any point here with all due respect just stating that it could have been a rare case you cannot give me that example as a fact.....

Regarding Tejas sir I know very little about it... But I do now it can perform .....
It might be a decade or two old aircraft but It has they aility to match all the Gen 4 aircrafts ... yes we are looking for gen 4.5 or 5 but we also need to have gen 4 you cannot give all the roles to those heavy aircrafts ....
Twin engine aircrafts do have greater ability ... going out of context F35 is single engine right...


U asked few Q one from my side...
can u assure me if Tejas lets say get twin engine some day ... Stealth coating and lets all highly complex control.... will IAF accept it?
If you can assure me of that after adding few more to that list I will rest my point.,,
Its not about inducting it its aout accepting it... Here is the machine which took alot of time to mature....
Which country has not taken time comparable to it... more or less all th eprograms have gone beyond time and cost with better machinery and tech.....

Meaning, it cannot exercise multiple capabilities in the same flight like Rafale or other 4.5th gen aircraft can (including Gripen NG and J-10B). Its only other equivalent cousin is the JF-17.

Don't forget that India is currently in an arms race, the west is not. Indigenous weapons don't win wars, good weapons win wars, history attests to this fact.
