The aircraft can end up being smaller than AMCA. So 100KN engines will be more than enough. I hope they choose EJ2x0 for this jet, there's plenty of growth potential there. But if ADA goes ahead with F414, even that's fine.
Twin-Engine Deck Based Fighter (TEDBF)
- Thread starter Gautam
- Start date
ADA had shown some designs of LCA MK2 for deck ops. At that time itself I had stated that we need a new design for deck operations and all the fixes given to LCA will not work. I had even called AMCA unfit for deck ops. The wing loading of AMCA is too high for deck ops, especially for STOBAR carriers.
Correct, I was referring to the inability to take off with full load. Rafale-M with 25ton or SH with 28ton. I'm not sure if Mig-29K can do it.
They need to change the wing design to a pure delta design which allows for BLC to increase lift for STOBAR launch. And a sweepback angle which allows max lift coefficient to be achieved at relatively smaller AOA with an aspect ratio of 3 or above. The modified MSA design now has 40* SB for this very reason with strong LERX to give a boost for STOBAR launch when the AOA suddenly rises to over 12* at ramp exit. This alongwith BLC system fed by the APU driven generator will provide the MSA ability to go at full load from deck.
Another aspect is that due to lower sweepback, for the same MAC, we get larger span and wing area with much higher CLmax. I have maintained the Re number of Mig-21 wing even in the new wing design.
Those loads are not possible anyway because of configuration.
Rafale and SH have 5 heavy hardpoints. Mig-29K has only 3, and even those 3 are not very impressive in terms of carrying capacity.
Both Rafale and SH can carry 2 Brahmos-M/SCALP/LRASM and 2 large tanks. Whereas Mig-29K can carry only 2 small tanks with 2 Brahmos. But all three aircraft can carry this loadout, and I suppose this is the heaviest warfighting configuration possible. Even then, the Mig-29K won't be able to carry as many AAMs in this configuration as the Rafale and SH will.
So even if MTOW is not possible, the Rafale and SH can take off with everything that we need for any type of mission.
I meant airframe and performance, not avionics. Like there's no need for IWB and supercruise. Avionics are going to have to be topnotch of course, preferably the same or of similar category as AMCA Mk1.
What about a non-delta design?
Aero Mag said Mk2 navy design is finalized, metal cutting done.
Will fly this year ..
Suddenly Project definition itself changes.
we can have Mk2 TEBDF later on.. Replacing MK1 TEBDF before the production starts so that it can fly from Cartobar.

My view is different,
We are trying to develop too many different designs
1. LCA Mk 1 A , yes go for it
2. AMCA, Good
3. Also make AMCA with the stronger airframe, and ability to be used from CATOBAR & STOBAR carriers
This is just trying to make sure its future proof
With AMCA and TEDBF having a commonality that might help spares management

For BLC to be very effective, we will need a straight trailing edge. and for that only Delta planform is the option. If they go for trapezoidal design like of present AMCA, the BLC may not be as effective.
super hornet wing is also delta wing with just 20* SB

With the current Tejas’ single General Electric (GE) F-404 engine replaced by two, more powerful, GE F-414 engines, the TED-BF will be a far bigger and heavily armed fighter.
The current Tejas Mark 1 gets airborne with a total “all-up weight” (AUW) of 14 tonnes. The air force version of the Tejas Mark 2, which will have a single GE F-414 engine, will have an AUW of 17 tonnes. And the navy’s Tejas Mark 2 (or the TED-BF), powered by two GE F-414 engines, will have a beefy AUW of 24 tonnes, says Deodhare.
ADA is targeting 2025-26 for the first flight of the TED-BF. The navy wants the fighter to be inducted into service by 2031, to replace the MiG-29K/KUB that currently flies off INS Vikramaditya and will also serve on board the first indigenous aircraft carrier, INS Vikrant, when it is commissioned in 2021.
Broadsword: Naval Tejas gets airborne with weapons, ready to operate from aircraft carrier by March

Long long back I had told you that IN intends to take over shore based defense of its onshore and offshore assets itself from IAF. And that IN will have about 250 fighter aircraft fleet to serve three carriers and shore based squadrons. IAF will not let IN do this job and acquire more fighters. It is for this reason, IN has decided to go for indigenously developed fighters. This will help IN outsmart IAF.
This IN-IAF-IA internal tussle will go away hopefully when all services are integrated under CDS and further plans.
No way. IAF is the worst of the three. Let them first handover all attack helicopters to IA.
So why not disband the IAF and transfer all the aircraft under its utilization to IA & IN, sounds terrific!!! As I said earlier, hopefully tussle will be the thing of past when CDS and other things including theator level commands under discussion get implemented. Thank you.
We do need an AirForce but yes, we need to streamline the system. The biggest obstruction to joint commands is once again IAF. We can probably assuage them by making CDS from IAF as a mandatory condition since the CDS is going to be a four star officer.
The IAF should stick to operating fixed wing aircraft and not rotary. Why are the Apaches and Chinooks with the IAF and not the IA.
