How is combat radius related to AESA radar or BVR? Supporting role means what? What is that you have to support? It is by 2023 that India will have 36 rafales. Tejas MK1 and MK1A will be definitely more than that Su30 MKI is enough. There is no need for more Rafales. Super Sukhoi is also...

Kaveri weighed 1200kg for 74kN thrust in 2011. Adding 20% weight to it would make it 1440kg for 90kN. This is the point of opposition. The point here is that TWR is important and must be 8. Thrust without TWR is not meaningful

That depends on what typeof officers are deputed to HAL. If worthless people with loud mouths are deputed, they will ruin it .But if intelligent people with proper understanding is deputed, they will sit with scientists and explain the problems and solutions asper their experience in flying...

AMCA is the stealth plane. There is no need for stealth Tejas. AMCA will be using Kaveri engines. Its MToW being just 25 tons, it doesn't take a new engine. Whatever engine goes into Tejas Mk2, same engine in twin engine format can be used in AMCA. 61|96kN Kaveri is good enough for AMCA for...

1220kg engine with 62/96kN thrust is good enough for Tejas MK2. The 100kg extra over F414 is manageable. Kaveri engine, despite being heavier than F414 for same thrust, will be much better due to its indigenous manufacturing and the associated perks. Also, AMCA has MToW of 24-25 tons which is...

No, I am saying that the TWR of close to 8 is minimum requirement. F404 has TWR of 7.8 and is the minimum acceptable TWR. So, if the idea is to have Kaveri with lower TWR than F404 by adding weight, it is unacceptable. But, adding another stage to F404 to make it as good as F414 is acceptable...

Adding an extra stage will not make it as contemporary as other engine but heavier The Mk2 weighs 8tons when empty and fully equipped with all the internal items and cannon. MK2 is having additional 1m length, larger wings which add to its airframe weight. Then it has AESA radar, SPJ, Laser...

Hardening means a process where metal or alloy is heat treated and then suddenly cooled. We don't do such things on engine turbine. Don't you have basic common sense about basic metallurgy? Hardening has no direction and is infact the opposite of it! I have told you that you can't have the...

Engine is the heart of a plane. It is like you want the size of your heart to be equal to heart of a buffalo but expect your body to remain the same size! Kaveri is made from 2nd generation Directionally solidified blades. Blades are not hardened but crystallised in a directional manner with...

India last year did the policy of funding private companies the reimbursement of development costs and they ended u designing fancy vehicles as IFV and presented it in defexpo! Private companies only do jugaad but not any R&D. If government funds them wholeheartedly, they will simply remake...

HAL has been consistent about december 2018. There is no need to mistrust. HAL only said that they hoped to get it by june but also mentioned that the actual deadline is december. They have been consistent so far and hence believable.

Kaveri is made for tejas Mk2. I don't see why 96-98kN is so worse compared to 100kN. What matters is dry thrust and Kaveri has more dry thrust than F414. Tejas Mk2 is coming in 2025 and by then India is unlikely to integrate foreign engines. Foreign engines came to India due to foreign agents -...

What are you saying man? Tejas MK2 will be using Kaveri engine, not F414. F414 is for prototype testing only.

When did I say that F414 has maximum dry thrust of 54kN? F414 has maximum dry thrust of 58kN. But it can run at lower than that. Just because your car has maximum speed of 100kmph does not mean you always run at that speed, right? So, what I said was that if F414 ran at 54kN and F404 also ran at...

That is why I said that the SFC matters. Also, if F414 and F404 run on same dry thrust of 54kN, F404 will consume less fuel due to the fan size of F414 being bigger which makes the energy required to keep the fans rotating higher for F414 and hence requires more fuel for same thrust. Turbofan...

The first forty MK1 and Mk1A are going to have F404 engines. It will be under production till 2020. Only later will Kaveri be needed.

When it is said that the engine is developed, it means it is developed. Testing takes some time but not too much. Multiple sorties in short span of time can be taken to get quick results in 1-2 years. Testing for other engines like F404 did not take much long and there is no reason to say that...

Moron, the F414 has same SFC as F404 which means that the fuel consumption per kN-h is same. Now, since F414 has higher thrust, it consumes overall fuel higher but not per unit thrust. When you add extra stages, the functioning of these will reduce SFC as well as increase engine size which in...

F414 has only 4% increase in weight over F404 and the thrust is increased by 13% while size remains constant. I don't see how it compares toy your 20% increase in weight and 20% increase in thrust while the size increases due to addition of stages. (I really did not want to reply to your...

Sometimes it si difficult to get the right words at the right time to articulate one's thoughts. That must not be considered as quackery
