Current allocations does not support your statement IAF, IA and Navy all said they needed more funds and the budget was insufficient.
Not assuming just check the last 10 years budget allocation any deal which goes into billions is troubled. Remember Rafale original deal People were concerned how were they gonna pay for it....
My guess would be Tejas Mk1
French have said it cannot go beyond 90KN
agreed....
F404 was to fill the gap and was more than what the IAF originally wanted for Mk1. As they say currently Kaveri is at 80 KN will it still not be sufficient given F404 is 85KN
4-5 years is doubt though yes it will take some time but remember the original design was for Kaveri only later modified for F404.
No one says that funds are enough no matter what. India is planning long term, not short and hence the idea is to develop technology and make strategic purchases that provides technology which will be used to make indigenous items in the future. So, the intention is not to buy items to improve short term strength but to buy items with ToT and reverse engineering ability to get technology. India has Su30 manufacturing wnd can make its own planes when needed.
Kaveri is 81-84kN with flat rating and variable cycle. Flat rating means that the thrust is deliberately reduced to maintain a flat peak thrust across altitude and variable cycle means that te bypass is changeable. So, 81-84kN would mean 100kN in normal terms. Why are you ignoring flat rating and variable cycle? WHat kind of engine ever uses bypass ratio of just 0.16? 03-05 is the standard bypass and 0.16 is only the least bypass value.
When did France tell this? Also, do you think India will not look at the design of F414 and the cooling vanes and other items used to optimise Indian design?
But you need to pay the bills. Imagine your expenses are more than your salary how will you plan to save for a house or car? when you cannot even pay installments. you wont... and same is the case with our forces when they dot have enough why will they put money in tech development.
Reverse engineering is not the field where we excel and to maintain superiority on the ground we need to buy.
Assembling is not manufacturing.
Its not perfect like Tejas like you said... perfect match
Its been quoted multiple times. Read between the lines in the article...
To achieve 100 KN, & to increase bypass ratio to 3&4, we need far higher Turbine Entry Temperature (TET).
How did you conclude this? Reverse engineering is much easier than developing one's own items. Revserse engineering does not mean exact replica but just getting ideas and understanding concepts
What bills one has to pay? Stop watching too many hollywood movies speaking of USA lifestyle.
Su30 is manufactured and assembled in India. do you have problems in english?
By unreliable source which has been disproven. Read the article you have and read the statement of french president. French president has denied any Kaveri engine development with M88 core as given in the article. So, the article is fake news.
India makes Al31F engine fully 100% from raw material stage. This is similar to F404 and M53 engine of Mirage2000 in technology levels and is one level below F414. So, India is not starting from scratch but ahs good enough expertise in making engines already. Prior to this, India made R25B engine for MiG21 in India.
Firstly its unethical to do that but keeping that aside I m not expert but even a expert will tell you that reverse engineering it not easy had it been everyone would have made everything. Leave everything aside you said we have been building engines for long then why are we not able to build a stable core for Kaveri. We can reverse engineer anytime right???
Bills: Salaries/Fuel/Rationing/ammunition/Installments those come under category of bills.
You can believe what ever you wanna believe. what % of Su is indigenous?
there would be many sources and you need not believe them and I am not here to convince you either.
Reverse engineering is not exact replica but understanding the ideas and concepts and thus reducing time for lengthy trial and error process. Also, India did not have access to high end engine technology, metallurgy to simply get things done quickly. Without infrastructure, it is not possible to reverse engineer. Also, Kaveri has been designed after understanding other engines and not imagined from scratch. But, due to UPA cutting funds, Kaveri could not even get a test bed and GTRE chief was saying in Aero-India 2009 that funds are being cut or delayed and test bed is not being approved. Kaveri will be built soon and in next year will see flight as this government has been supportive
Everyone knows this. Budget is allocated according to needs of fixed payment and additional capital for technology acquisitions.
Engine, airframe, avionics are fully indigenous. BARS radar is also indigenous but may not be fully indigenous. a few items like IRST, EW, ejection seat, minor parts like nuts and bolts and raw materials like titanium for airframe is imported. Except for IRST, India can make other parts but still import due to contractual obligations. Otherwise, Su30 can be made fully indigenously except for IRST
Fake news must not be considered as sources. There is no news about Kaveri being developed with M88 core from either India or France but simply a fake news by detractors who don't want India to have indigenous engines and instead want to exert pressure on India to import foreign core
Yes only in my dreams or by the fact that IAFs rejected the Kaveri / Snecma engine in the first place, in fact IAF had doubts if the joint engine will reach 90kN at all and if there actually was a joint development, or simply a replacement of Indian parts with French once. You could also add the fact that ADA itself required up to 95kN for MK2 and let's not forget that this requirement was made nearly a decade ago! In the mean time, LCA got heavier and heavier and the MK2 initially was not planned in the medium class either. So if they Base it now on the weight and performance of the Mirage, 90kN obviously can't be enough for MK2.
Smokescreen makes it sound like there is something nefarious about the intentions.
Any tech development is based on requirements, but the US prefered to develop just a longer range AIM 120, while Europe understood that speed not range is the key and developed Meteor.
Other than the delta wings, they don't share anything design wise. High wing on LCA vs low wing on the mirage, air intake positions, different twin seat design, weapon station layout similar to Jags...

Not quite!
Modern jet engines get,
The TWR of engine is also about fuel consumption, optimal thrust for weight class of plane etc to optimise range. Bigger engine means smaller fuel tank in the plane, thus lower range. Bigger engine consumes more fuel for sustaining itself and hence more fuel wasted to sustain itself rather than propel the plane. The fuel conumption per unit thrust goes up even though TWR stays same as more fuel is needed to maintain engine due to overall increase in dimensions and moving parts
I would highly recommend to you to read more and inform yourself, no matter where and from whom, because you have a clear lack of knowledge and understanding for sure. I don't need to go to other forums, since my aim is always to seek and "share" credible infos wherever I am =>
