Anons, answer me, why can't we have an Air Force variant of TEDBF i.e ORCA powered by twin RD-33 engines ?

TEDBF Project for now is not even get any funds. There seems to be Preliminary study and Navy is interested. But to get funding, Navy is trying to convince IAF to use the platform for Air Force Variant which is ORCA. Basically, they need to show sufficient requirement numbers to get funding from GOI.

Till now

1. IAF wants 114 MRFA (Rafale)
2. Navy for now fixed the Air wing by ordering 26 Naval Rafale for Vikrant. So far there is no sight for next AC.
3. After MRFA, MWF IAF will going to 5th Gen platform in the form of AMCA. Now the ORCA timeline does not make sense for them.
4. Similarly based on the timeline Navy themselves may think about an 5th Gen Naval Fighter.

Unfortunately the proposed design got stuck in an situation where we are trying to transition to 5th Gen platforms.


Also even the baseline Kaveri can be used for this project which uses the existing CMSX2 Alloy. We already have 3rd Gen Alloy in the form of DMS4 alloy which gives you even better performance number.

Depends on how good the afterburner section that Corporation is building. Dry thrust is around 54KN and if they get the afterburner good enough we can see solid 80KN Wet thrust. Since TEDBF is twin engine fighter so problem.

UN Import Marshalls are set on more Rafale.

This is what a TEDBF would look like



Ignoring my usual rants about dalali by the Import Marshalls, logical arguments against them going for Orca is

>This will be a development and production project, will take much longer than Rafale and will have a lot of bugs and other niggles
>Assume optimistically delivery and induction is 10 years from today, by that time you will see 5th gen and above stealth planes being the mainstay in our adversary's fleet
>We have a something called AMCA, development wagera of this would take away both time and funding from that.

imo Admirals must also junk this plan for TEDBF and opt for a Naval AMCA, which would be larger and have capability for external hardpoints aside from the internal bay

Then maybe you havent seen the latest progress shared by shirobarks and shreedhar singh, the alloys progress is good, tbc coating has been developed, cooling holes improved, blisks made for kde, new distortion tolerant inlet fans for kde, single crystal alloys would be used
Lots of weight reduction measures underway, metal bypass duct would be replaced by polymer matric composite duct, maybe but not sure

Still it will take atleast a decade for Kaveri to enter series production even if we start serious funding today

 

[Hawkeye]

Not a popular opinion but if IAF is not willing to take ORCA based on TEDBF and IN is also thinking about 5th gen plane, it's better to develop a deck based 5th gen plane given that money is actually released for it right this year to compensate for time loss. Ideally, we should have 4+ and a 5th gen deck based fighters combo for aircraft carriers.

Imo Engine supply chain reliability is more important than engine reliability itself, aircraft powered by unreliable russian engines with reliable continuous supply chain is always better than aircraft powered by reliable murican engines with unreliable supply chain

Atleast now, develop an Air Force variant of TEDBF powered by RD-33s

Chinese were absolutely brilliant with J-20 powered by AL-31s

No it won't, once the dry version gets certified it would just take a couple of years for it to get certified and enter production

Thiruvananthapuram will deliver the afterburner section this year
Lets hope that drdo gets slots for testing the kde onboard the testbed and soon we will snap on the afterburner and test it

And @Anonymous Bharata it would be utter foolishness to go with smoke chimney rd33 when we already have a better engine in the same dimension

If I am the designer I will always choose a production ready available engine instead of an engine which is still under development

Kaveri will take 10 years min, you have to first fly the Tejas with Kaveri in limited flight envelope , then slowly expand its envelope, you have to to do LSP, then SP, you have seen how much time it took to establish the supply chain for Tejas, it will be even more difficult for Kaveri and no it's not coming anytime soon

So RD33 is the best option today, you can integrate Kaveri when we are churning it from Production line

As of now TEDBF is only concept on paper By the time TEDBF comes out IAF will be fielding 5th gen AMCA in numbers so a twin engine 4.5 gen fighter is not need we have Rafale and another 36 if procured is enough.
If and only If need arises airforce version can be derived from TEDBF.

Russian engine supply chain is also unreliable because of corruption, chai-biskoot PSU delays on their end also and their current war.

However unlike the Burgericans they aren't malevolent to stop your supply over some made up bullshit just to punish you for some geopolitical sin you have committed.

As for why the GE F414 is shoved in everywhere, beneath the figleaf of "Western engines have better MTBO than Ruzzian engines" lies the nangapan of pro-America dalali

Better we invest more in suk30, until kaveri not ready. GE engine anyhow problem will come in future.

Bookmark this, by 2027 burgerch0ds will pull the rug on F414

Redesign AMCA around RD-33, (call it AMCA-Mk1A) , yes its already very late, but you have no option because indigenous engine is not coming anytime soon or we will end up with nothing
