Tejas Mk2 (Medium Weight Fighter) - News and discussions

Trapezoidal is a form of Delta. Even the LCA wing has a sweep forward of 4* at the trailing edge. It is not a pure delta.
Not even in mk2. So it would be miracle if we still manage to make it marine worthy.
So the entire project ends in failure. What were the last mile glitches that were to be sorted out by Safran all about? Last heard they have certified the Kaveri to be good enough to undergo limited envelope flight testing. What's all this now? @randomradio ; @Picdelamirand-oil
Can you gentlemen shed some light on this?
As of now this engine is fit for flight trials and certification but we dont have a platform where it can be used either as single engine or twin engine. This engine needs to shed weight a become less than 1000 kgs from nearly 1060 kgs that it weighs now.
Sir, is that the only reason why it won't be powering the MCA or the AMCA?
Is this such an insurmountable problem ? Can't we source test beds to test its efficacy? There were articles earlier on how we could do so by procuring a MiG-29 from Russia. What happened to that concept?
Ideally a new engine must be tested on a flying test bed like the Gramov IL-76 or on a twin engine jet. I am not aware of any Mig-29 being made available to GTRE to fly test this engine so we are going to use an LCA for it.
If we are going to use the LCA for it, assuming it proves adequate for the job, can't it power the MCA then? Or will we require better iterations of it, another round of testings to go with it and the same old problem of not mating a new engine with a new plane?
What's the future of the Kaveri program then? What about all that talk of designing K 10, K 11, etc? What happens to them? Will they be using better iterations of the M88 core? What happens to the Kabini core then? How will using the M88 core to power the K9 help us in gaining technological know-how of designing optimal cores? What about IPR, ToT, etc for such cores as SAFRAN supplies? Will GTRE be co owners of the IPR in case better iterations of the M88 go into the K10, K11 etc?
In earnest anticipation of a response.
i think just because Doval does not want others to know what a failure it is is the only reason this program is making headlines in defense shows otherwise we are very much ready to dump it and move forward with completely different options
The engine is fine. But it does not deliver enough power for all of our manned aircraft, only UAVs and UCAVs for now.
K10 will be developed. As will better variants. We need a domestic engine at least for future programs, if not AMCA. The SAFRAN-GTRE engine will see transfer of IPR.
If you recall I pointed out that the French will likely only give us outdated tech in order to make K10 suitable for operation within its design envelop. This won't be enough for AMCA. Maybe more modern engines after K10 will be made with French help, we are doing it in our helicopter programs already, but none of these may be ready in the 2025-30 timeframe for AMCA. Perhaps a GTRE engine may go into AMCA Mk2 in the 2040s.
Plus, there is a good chance someone else may have given us a much, much better deal, which GTRE may not be able to match, in order to power the AMCA. AMCA needs a very high end engine if the program is to survive. It can't be half-assed like LCA and MCA.
The problem is there's never any guarantee with engines. It either works or it's a bust.
Kaveri with Kabini will be used in IUSAV.
I do not have that information. But if the engine is ready for flight tests, then it must have already achieved that benchmark.
Can't stop myself from doing stupid calculations... So hear they are...
Max. take Off Weight =17.5 tons
Weapon Load = 6.5 tons
So Loaded Weight = 11 tons
Internal Fuel = 3.3 tons
So empty weight = 11000 Kg - 3300 kg - 500 Kg (Additional Load) = 7200 KG (7.2 tons)
Fuel fraction = 30%
Wing will be around 40 sq Meter
So wing loading should be around 275 Kg/Sq Meter
If an 70/110 Kn engine is used then Trust to weight Ratio will be 0.65 Dry and 1 max.
ADA defiantly have tried for a very good plane in terms of specs at least on paper.
