I have always preferred twine engine aircraft over single engine one because we can make 30 KN dry and 50+ KN afterburner easily compared to 60 KN dry and 100+ kn wet. The more important aspect is that we can tweak for Navy as well. That can save lots of our efforts. 35 KN dry engine can give us a highly potent aircraft. If we can put TVC in it, it can only be compared with mighty MKI and substitute MKI in many roles. It will be a great saving in operation cost.

HTFE25 hasn't been developed so far....

Q for the gurus.. aren't MWF, ORCA, Tejas Mk 2 the same? Or am i missing something here? and TEDBF is just navalised Tejas Mk 2, just like NLCA to LCA Mk 1.. so IMO there may be many names but ultimately it is just

1. Tejas Mk1/Mk1a- single-engined light fighter (replace mig-21)
1a. NLCA - its navalised version (may serve on INS Vikramaditya and INS Vikrant),

2. Tejas Mk2 - twin-engined medium fighter (replace mig-27/mig-29/jaguar/m2000 as & when)
2a. NLCA Mk2 - its navalised version - TEDBF

3. AMCA being the 5th gen program

of course they will have twin seat/trainer complements as appropriate.

Tejas MK2/ MWF are same. (Single engine)

NLCA is just tech demonstrator

Naval Tejas MK2 is cancelled for TEDBF(Will be completely new design or maybe a non stealth version of AMCA will know by 2021)

AMCA is a 5th gen program

I have no idea from where this twin engine ORCA came from.

 

[Steven Rogers]

MWF/TejasMK2 is a single engine fighter.
NLCA MK2 is not TEDBF

NLCAMK2 is scrapped then,TEDBF has replaced it and it is gone...

Twin engine fighters does have higher operating cost compared to single engine one. Also it should be normally higher weight.

It is already under testing. ..............

All engines with similar technologies have almost same same T/W ratio. So weight shall be in proportion to thrust it produces. So not weight penalty. Same is true for fuel consumption as well. Why I advocate twine engine is because of two reason.
1. We can easily produce 30/35 kn engine compared to 60/70 KN engine.
2. We can comparatively easily make naval fighter out twine engine fighter.

Else , I am ok with single engine fighter as well but that will make us dependent on others till we get our own engine which is likely to get almost a decade.

I wasn't talking about engines weight but the twin engine configuration fighter of same size. But that's not always true.

 

[Vorschlaghammer]

ORCA = Omni role combat aircraft ? As in Dassault's designation for Rafale ?

 

[HariPrasad-1]

Twine engine configurations are mostly for medium weight planes. When higher power is required,twine configuration is used because getting high power is comparatively difficult from single engine fighter. In thumb rule, power*25=MTOW is the power requirement of a plane. Now when MTOW exceeds, 20 tons, dry thrust requirement exceeds 80KN. There are very few engines (One of such is used in F 35) which can generate this much of power. That is why twine engine configuration is required. Twine engine fighters adds to the safety of the plane.

Both twine engine and single engine are needed,

twine engine for high end / high performance/ high cost / quantity is less
single engine for low end / low performance/ low cost / quantity is more

NLCA is just tech demonstrator

Thanks for clarifying.. ADA has quite a smorgasbord of fighter programmes.. but there is contrarian historical evidence to whether they will be on time or anywhere near it.. even F-35 is massively delayed and over budget.. however, what warms the cockles of the heart is news like https://english.manoramaonline.com/...istance-deck-operations-ins-vikramaditya.html .. NLCA is under active consideration for deck landings on INS Vikramaditya!

Single engine is easy to maintain... less turn around time and more of a workhorse.

So, the cockpit of Mk2 finally emerges. Of course this is from sport, but im sure this cockpit will find its way in mk2 as well

Can I get original URL for tender?

 

[Defcon 1]

Tell me what other design institution in the world in handling about half a dozen big ticket aircraft programs(ie is designing and developing the aircraft)?

Actually a lot:
1. Lockheed martin: F16, F22, F35A, F35B, F35C, TR-X, RQ-170 Sentinel, etc
2. Boeing: F15, F18, F/A-XX, XS-1 Phantom Express, Phantom Ray, X-37 etc
3. UAC: Su-27 flanker and all its variants, Su57 Felon, S-70 Okhotnik, Mig 35, PAK DA, Mig 41, etc
4. AVIC: J20, J31, JF17, H20, J10 series,Wing Loong, etc

Please note that I have only included fixed wing military aircraft and excluded support aircraft such as transport and AWACS, civilian aircraft and helicopters too. If I include those in this list too, the numbers will easily triple.

We only have 1 credible aerospace agency,

No, this is wrong impression, we have at least 4:
1. ADA: Works on LCA and its variants, AMCA, Ghatak UCAV
2. NAL: Works on civilian aircrafts such Saras and NP5
3. HAL: Has inhouse R&D for works on trainers like HTT40, HJT36 Sitara, HJT39
4. DRDO ADE: Works on drones like Lakshya and Rustom.

having one more would create competition and will be good for the aerospace industry in the country.

No, not necessarily. Creating competition would be good only if they are private entities where competition would drive efficiency. Creating competition here will simply lead to duplication of posts, duplication of work, hindrances in transfer of knowledge. A very good example is Indian shipyards. So many government shipyards are present but they can't beat the private ones in bidding.

Yea even I was thinking if this even a real project or not.

I think it could be available in drdo website
