    Ive never seen afterburners engaged in LCA(GE F-404 engines)in any of the pics available on net.is it bcos 404 is low powered or jus that hal doesnt wanna spare extra fuel for the show.

    "power upto 100 fighters (with an option to power 60 more)"…that's it? I would have imagined at least double that number of LCA's taking to the skies. Any scoop on the final number of Tejas' to be inducted and eventually/hopefully exported?

    General Electric's F414-GE-400 for the Tejas LCA Mk2 and General Electric's F110-132A for the F-16IN Super Viper. GE will sweep it all…game, set and match! GE also gets to set up an engine MRO workshop for CFM56 and GE90 turbofans at Nagpur, thereby overshooting–in dollar terms–the MoD-mandated industrial offsets requirements. Just prior to announcing the M-MRCA competition's winner, the MoD will announce that the the DPP is being 'modified' to recognise the strength and value of 'strategic' indirect aviation-related industrial offsets.

    Shiv,
    I am 21.Somewhere down the line,i'll be telling my kid about a plane named Tejas that's was our product but never came into action.Believe me i can make a fighter plane faster than ADA with hook or crook.Damn these guys…..all you hear is flight tests.Make me Defence Minister and i'll teach these people how to work.

    F414 is definitely a powerful engine but its add-ons include American sanctions and no support during time of likely conflict with PAK also one should take into consideration that the EJ200 will be comming with thrust vectoring also ej200 is better than RD33 refer to wiki which is what is required LCA is ligher than the JF17 and also with EJ200 it can stay ligher agile and will require less fuel also the range will improve thats what I feel but everything will be decided by ADA Air Force and Gov. All the best to them

    The Eurojet EJ200 (same engine that powers the Eurofighter Typhoon) would provide supercruise capability for the Tejas.

    414 is the best. It can be serviced on a carrier thats moving up and down and that is suitable if the LCA is ever going to be navalized.

    how much ToT will GE allow for its F-414 considering how tight US export restrictions are ? and if in the future, the Tejas can be exported, a US engine will definitely be a no-no because any product that competes with the F-16 will not get US permission for export. the same problem came up when Boeing was to give consultancy for ADA on the flight test program. It was also seen on the South Korean F/A-50, where South Korea was not allowed by the US to put an AESA because of a clause in the contract that Lockheed Martin signed with KAI, that the F-50 should not have a more potent weapon system than the F-16.

    Would ADA and GOI go for the GE414 knowing well the Americans have a penchant for sanctions and technology denial if India does not toe its foreign policies? What about the ever present end-user clauses in the bilateral sale and purchase agreements?

    It would be wiser and safer to go for the European aero engine. At least we won't be left in the lurch should a conflict or all out war take place with the Pakis who are more all weather friends of the US than India can ever be.

    Hope good sense will prevail. Hope MMS and the coterie of gullible leaders do not fall for the American sweet talk. It could become very painful and demeaning for India.

    EJ200 is lesser than GE414 by 120 kg.
    60 % TOT is announced for this project .
    I don't think General electric will transfer 60 % TOT.
    The single advantage GE has is 98 kn

    India is almost selecting Defensive weapons , India Hardly needed offensive weapons . most of the offensive weapons are in problematic ( Howitzer guns , Fighter jets ( to stop depletion) , Long range Anti tank missile & MBRL , Submarines, Longer range bombers TU-22 M3 backfire. DAC should need to go Fastrack .

    Dear Folks ,

    How come we are talking about an LCA Mark II when there is not even LCA Mark Zero .

    As an Indian I have to say with a very heavy heart that its time to end this never ending tamasha and go for an immediate interim replacement for Mig 21 – be it a Gripen or a Mig 35 or F16 ( considering the tomfoolry going on even a Spifire would be welcome )and leave the choice to the pilots and not some bloody " bureaucrat/technocrat/mediacrat/***crat"
    Make a choice and go the whole hog in implementing the choice.

    Secondly, give a timebound plan to the Indian developers to convert LCA into a mid level fighter bomber to replace the Mig 27and Mig 21 in that role. Basically a poor man's bomb truck with secondary air defense capabilities to make up the numbers. That in itself will be an achievement.

    There is more to engine quality than just wet thrust. The Chinese know this, which is why they're still fooling around with their first 4th gen fighter engine.

    Reliability, operability, readiness, reaction, control, materials, cooling, pressure, stage temperatures, component life, part swapping, engine access, feedback monitoring, MTBO – all important.

    Welcome to the big leagues. Unlike Russian engines in your Mig-29s which had to be pulled out and thrown away like a condom after just as low as 100 hours, the F414 is designed to stay and perform for as long 2000 hours of flight.

    Excellent piece of engineering.

    I don't know much about EJ200 but they are made by Eurofags. If you think the US is sanction-friendly, wait till you see the Euro Court of Human Rights.

    I have a few possibly naive queries.

    1) Both the engines will require gearboxes. Are these integral with the engine – or is a separate gearbox being mated ? Will the position of the Gearbox in a EJ200 be same as a GE414?

    2)The higher the bypass ratio – the more volume of air is needed. I understand that EJ200 is a higher bypass engine – will the existing inlets work? The practice of creating additional inlets may increase the RCS.

    3)The EJ 200 can be set for higher thrust with a "life" penalty – The GE 414 EDE can have 20% extra thrust or greater life

    4) Thrust vectoring : while EJ200 has thrust vectoring – that would add a weight penalty – negating the lower weight. Also – the FCS would need significant changes – and given that seems to be a challenge today (see the slow opening of the flight envelope) – would it not be better to stick to a conventional design with low maintenance ?

    5) Growth – Both GE414 and EJ200 have significant growth programmes – upto 20% increase in Thrust.

    It may be important to assume that LCA MK2 will be overweight by at least 10% – given the record so far….. Hence, we should order the engine accordingly

    I guess there is a mistake in the article.

    You said "While the EJ200 powers the Eurofighter Typhoon, the F404 powers Boeing's F/A-18E/F Super Hornet as well as the JAS-39 Gripen IN"

    I think it's GE 414 Engine that will be used in F-18 and Gripen IN (for MMRCA) not F404. Isn't it ?

    Correct me if I am wrong or update the article if you are ­čśë

    F414 is a little long in the tooth and has almost exhausted its growth potential. EJ200 on the other hand has a more modern thermodynamic cycle and ample growth potential. Its an engine much smaller to the current F404 powering LCA and can accomodate a larger Low pressure fan to increase thrust to over 100KN. Such a modification has long been planned but was never required by EF customers.
    Even in its current form EJ200 has a higher dry thrust to F414 and requires less air flow. Air intakes of LCA will have to be redesigned to accomodate the greater air flow requirement of F414.

    TO Shiv and Prasun

    EJ200 vs F414

    most of the time fighter doesn't use afterburner main thing is the dry thrust

    so when looking at dry thrust there is only 2kN dry thrust difference between F414 and EJ2000 while EJ2000 being 120kg less in weight.

    DIAMETER

    EJ2000——- 29 inches
    F404——— 35 INCHES
    F414——— 35 inches

    clearly shows EJ2000 can be fitted with structural modifications.

    While lowering the number of inventory types is laudable, having engines from same manufacturer ( especially if it is USA) for both MRCA and LCA will mean that in the event of sanctions, a large part of the IAF fleet will be grounded!! Something I hope the IAF keeps in mind

    F414 it is and not F404.

    Also, they are testing two brand new engines for the F-18 – to replace the current engine. So, growth potential (if that is a concern) should be pretty good.

    However, IF the F-16IN is selected then alll this is moot.

    EJ2000 is definitely the more compact engine and will make an easy fit into Tejas. But what about MRCA then? Both Rafale and Eurofighter are frightfully expensive to buy and maintain, we will have to work with Saab and certify the Gripen NG MKI with the EJ2000 which will add at least 8 months.

    The solution to that is to stock up the spares. Buy lots of spares and consumables before you order the engines, and stock them at different locations in the country. Thus we can survive any sanction for long time.

    I don't understand why our babus/netas don't order a lifetime worth of spares with engines. Always looking to maximize bribe potential…..lowlifes.

    Wait 1 second. You want to cooperate with the world on crucial technology like weapons and arms control, but you don't want to play by the rules? You want to have a credible civilian nuke industry yet you want to test nukes whenever you want?

    What the hell. Just because you are able to wag your head like a thambi or have an all year round tan doesn't make you special, or the fact that you can buy a few planes doesn't make you sacrosanct from technology leaking rules. If the USA didn't make countries play by the rules, India would be in pieces by now.

    This is the babu thinking isn't it, just because you have a bit more dollars than others, you can do what you want like keep debt indentured workers or treat people serving you like shit, because you are outside the rules. What happens is India is reflected in your attitude towards other countries.

    No one is testing nukes anymore for good reason. And if you do, they won't play nice. First mover advantage. You should have thought about that before practicing socialism in past decades. Cry to the UN, they will make you a superpower. Hey wait…

    I like India. I really do. But you lot have screwed up the country for decades, I must speak out. Hindu rate of growth anyone? You are one of the few democratic countries who chose to embrace the Soviet Union and its idiocies and now you want to complain that other people have moved far ahead of you in technology and wealth. Your leaders consistently made bad decisions and your people refuse to own and acknowledge them but blame everybody else, but especially the USA, for you ending up on the losing side of things. Tears, I lick them off your face.

    Tough nuts. If you want to be a superpower and a locus of power, you have to do the rough and tumble, and not possess the attitude that other countries must groom or mentor you to greatness, pushing policy baby food into your mouth and siding with you on everything (cough Pakistan) or else you will throw a tantrum and not buy the things you need but buy second rate equipment and when you get whupped, you blame the USA again for not being the sugar daddy enough for you to choose to buy their weapons although they were always available.

    The 'sense' in going with EJ2000 is its compact dimensions, and the ability to upgrade to a bigger fan later for higher thrust variants. The 414 is decent engine, but EJ200 is built with the lessons of 414 being kept in mind.

    Most of the cost difference is due to the higher volumes of 414 compared to EJ engine. For a non-client country like India, a hundred million is nothing to protect sovereignity. The lessons learnt from ToO and assembling EJ200 will help the domestic programs immensly. GE is never gonna ToT anything, no matter what it says on contract. They don't share anything about engine manufacturing with Cananda, UK and Australia, so forget us Indics.

    Since f18,eurofighter has twin engines. But lca can accomodate only one engine. Can you tell how this possible. You are telling that f18 has f414 which has 98kn. Both the engines combined has 98kn or each engine has 98kn. Iam not able to understand this. Please clarify. If lca accepts f414 will it have twin engines like f18 or single engine with double power.

    Something doesn't add up with Tejas LCA aircraft.

    JAS Gripen which weighs 6500kg uses F404J (80kN thrust) has a speed of mach 2.2.

    LCA Tejas weighs only 5500kg with F404-GE-IN20 (83kN thrust) is underpowered?

    Something is not right with the claims that the F404-GE-IN20 is underpowered.
