TAI TF-X / Milli Muharip Uçak MMU Kaan

[Deino]

The 21x14x6m specs for the Kaan where most likely either carelessness or counterintel which I fell for, just like the Hurjets initial 35m2 wing area which was more obvious to me to be BS.

And the MTOW of 60.000lbs for Kaan is still BS for now and should be discarded. MTOW should be 75.000lbs with the indigenous engines.

So slowly you are questioning "official" data?
That indeed too looks like BS again, raising the question how much of what was posted here already and presented as "it's from official sources" but rated critically by others (like me for what we always get a lot of hate) is in fact BS?

... and still you think 75.000lbs with the indigenous engines (= 34,0t) are more reasonable or even realistic?

I've to correct myself. It seems the official figures given by TAI doesn't correspond with the actual size of the prototype. According to various sources I've gathered the Kaan has a length of 20,2 meters, a span width of 13,32 meters and a corresponding wing area of 70 square meters.

The length between the nozzles and radar array is now 16 meters with a theoretical empty weight of 16,8-17 tons which results in a thrust-to-weight ratio of 1,55 and a wing loading of 242 kg per square meters.

Sorry for all those who I've given a hard time.

... and still you think 75.000lbs with the indigenous engines (= 34,0t) are more reasonable or even realistic?

What's your estimate then?

You can't believe official data only when it is in your favor.
Or change the data on the airshow display board according to your preferences?

The official specs of Kaan changed from 19m*12m to 21*14m to 20.3*13.4m

My latest measurements (20.2*13.33m) got close to the latest official dimensions and corroborated by @Radonislav (who knows a bit more than he is willing to say)

When it comes to official MTOW, it used be be 60k lbs, then >60klbs to 60k lbs back again. If you think a stealth fighter with IWB with the same size of other twin engine heavy fighters weighs a whopping 15klbs-20klbs less than its counterparts, I got a bridge to sell you

A MTOW of 70-80k lbs is most likely, so I took the figure in between, 75.000 lbs


I know it's difficult to keep track of it all so if you don't follow the progress daily, it's best to just lurk

You should communicate with the staff of TAI and ask them to change the technical parameters instead of just "pondering" in the forum.

You both have a point. The Turkish military-industrial complex is infamous within Turkish MilTwitter for its poor marketing and public relations, and TAI is one of the worst in this regard.

He's right that Kaan's dimensions have changed twice so far (three times if you count the PDR). While the updated specs for Hürjet are for its second prototype, Kaan's dimensions are based on the P0/GTU-0, as evidenced by numerous open-source investigations.

The current given MTOW hasn’t changed compared to the previous one from the PDR. While advanced tooling and manufacturing can play a significant role in decreasing weight, the majority of us believe that Kaan's empty weight and MTOW that are given to us are outdated and that they should in truth align more closely with Kaan's in-class equivalents (such as the J-20, F-22, and Su-57)...

Before TAI manufactures P1, there is no point in insisting that his own estimated data is more appropriate than TAI's data. This is my opinion.

He's saying that TAI's social media and website managers hadn't updated the dimensions and specs until very recently, not that the people who designed the plane are somehow wrong.

Ok, the data from TAI isn't enough to make him happy.

In fact I don't have any ... as long as we haven't seen P1 and can identify how much it differs to P0, as long as the new indigenous engines is not ready and at best some fancy PowerPoint-sheets, anything - even from TAI - is useless!

It is as useless like similar fancy illustrations and projections from Indians and HAL, the Tejas Mk.2 will finally be "whatever" and "when there's finally a new indigenous engine also for the AMCA, THEN ..." ...

Let's wait until then.

 

[Waterballoon]

There's a significant change in height between the P0 and P1, perhaps the reduction means the vertical slabs have shifted to the tail section

I know placement of twin tails can potentially have large drag implication, also could interfere with vortex flow off the forebody. Anyone can theorize what possibly be reason why the tails move from positions that enclose the engines from the side to on top of the engine?

The vertical stabs are still on top for P1

Kaan's IRST and EOSS, or at least downgraded versions of them (as far as we can guess), are set to start airborne tests on UAVs.

Aselsan CEO Ahmet Akyol confirmed that the tests for its TOYGUN and KARAT products would take place on a UAV platform as efforts continue to progress its “challenging” technology roadmap into 2025 and 2026.

The chin mounted sensor is shown in the artwork? Looks like it has all around coverage. I wonder if it could be used simultaneously with the nose mounted sensor to provide all around battlefield awareness. With AI decision making software integrated it could provide pilot feedback on whether to engage aerial or ground based targets first.
