TEDBF or ORCA Updates

Ok, that changes a lot of everything we assumed TEDBF would look like...
If they found that tailed-delta to be useful, then it may have tailplanes instead of canards or levcons.

They'll probably end up selecting a Design which is not only suitable for naval operations but can also be easily converted to air Force use. Just like rafale.

But if they are going for tailplanes, why go for this design and not go for AMCA design barring the stealth features, a design which they have extensively tested and is also close to prototyping phase?

How this design stand against Delta wing design + frontal canards??

I really found that canard design sexy, floating on internet
Every light to medium category plane of same Tejas design,should have given a look to Rafale design

Sorry but i have different opinions this total delta frame designs looks like a little futuristic. Their are very few aircrafts which have big delta wings and no canards.

Yup total Delta has a 6th gen concept vibes.

But what about enough large internal bay's.

Tedbf won't have internal bays obviously . But it's next gen evolution could very well be full stealth later .

With all these designs we are only beginning.

Just like we have AMCA is design when mk1a and mwf are being build up. Same way we will have 6th gen fighters in design phase while tedbf/ orca / AMCA will be manufactured in 2030.

One possible reason to use stabilators instead of canards could be reducing frontal RCS

But then the Dilema's of back RCS's.

Naval jets mostly take off with drop tanks for additional range and safety and anti ship missiles are also huge so RCS is not a prime concern for them .

Still whatever can be managed should be done.

Don't think so....remember stabilators are all moving surfaces unlike stabiliser-elevator type conventional configuration.....also by that logic if rcs spike due to canard deflection was a real concern then mwf also wouldn't have canards....

 

[IndianHawk]

Iirc initial graphics by ADA had canards but final design could be changed. Atleast 3 designs are in consideration.

 

[Bleh]

Firstly. That is a possibility. For all we know, it could be changed like this.

But if they are going for tailplanes, why go for this design and not go for AMCA design barring the stealth features, a design which they have extensively tested and is also close to prototyping phase?

Because NLCA Mark2 is already a modified, naval operation capable design of Tejas & they'll just be expanding it. AMCA is way different. It'll take radical structural changes... Possibly wing size/wheels too.

Audit will end up a half-assed naval fighter like Mig-29k or Su-33, both incapable of taking off with enough payload from sky-jump carriers.

How this design stand against Delta wing design + frontal canards??

Fuck if I know. The tail-plain (of the keep them) will have drastic effect on behaviour of the aircraft. Too hard to guesstimate by looking.

That makes sense. But we optimised NLCA the same way and it was able to fly perfectly. We can pick up any of the 8-9 old designs of AMCA which has the appropriate proportions.

 

[Bleh]

Older AMCA versions aren't that different... Just minor design tweakings to optimise performance parameters.

On the other hand compare how drastically different the these two are!.. Only vertical fin & radome is common.

Yeah its more likely an afterthought than the primary reason. Though I would say canards are more contibuting to frontal RCS than stabilators (hidden by wing and body most of the time). There was some paper about focusing on rear control surfaces than fore control planes to reduce frontal and lateral RCS (which matters more than rear RCS). Maybe TEDBF is more focussed on relative stealth than MWF ( one reason I see is DSI being used in TEDBF which has stealth overtones and is otherwise in my opinion a liability).
What could be other possible reasons?
Greater pitching authority?
Additional lift producing ability?
