TR TF-X KAAN Fighter Jet

[blackjack]

A world leader in turbine engines, like Rolls Royce, still hasn’t got a working engine to fit in to the Tempest jet fighter.
The demonstrator plane will have two EJ200 engines powering it.
We need to give some slack to TEI and Tusas. You can not hurry these high end engine developments.

Forget about all the time they had to design a flat nozzle 3d thrust vectoring design. I already have doubts with the photos they are sharing because they don't even display round serrated nozzles most 5th gens display (excluding 2). I don't know about the world leader part if they have not shown the simplest stealth design in their engines like this.

The shitposting in the past on the Su-57 and KAAN nozzles will be long forgotten because it won't compare to a 6th gen(Tempest) flying around with round nozzles (not serrated with teeth even) is going to cause heart attacks if they really are flying a demonstrator in 2027 from what you have shown me.

It seems you have not read the complete article. RR and IHI are developing the 6th generation engine that will eventually power the Tempest.

This engine is an industry demonstrator engine, that will fly the plane and give data to engineers in correcting and redesigning the plane should it need, until the correct engine is ready to power the plane. Similar to the F110 engine we are using for the KAAN.
In its current form the EJ200 engine delivers close to 14000lbf. RR has actually manufactured a 16200lbf dry thrust version of this engine and was confident to reach 17500lbf dry thrust. For testing purposes this is adequate.
But the actual engine of the tempest is going to be nowhere near this engine in terms of power and technology . For one thing it’s design particulars included adaptive cycle technology.
So I wouldn’t “judge a book by its cover” yet!

About RR (in conjunction with others) not having developed an engine for Tempest yet - GCAP has yet to be given the go ahead. It was in project evaluation and definition phase for the its first few years of existence. With the project on course to be launched in 2025, the nature of the engine design chosen should become more apparent. I hope the electrical generating capacity of the engine will be revealed. Little info about the aircraft has been released over the years but I have heard/read that 500Kw-1Mw generating capacity may be required from the engine.

You are dragging my comments somewhere else and making up assumptions.

There is a reason Korea went with the KFX program. If you create a airframe that is larger than the F22 with engines less powerfull than a tiny f16, you have created a very inefficient product. It takes countries 8-10 years to create good engines, this goes for countries that CAN make those(Russia/China failed btw). Countries that can't, don't. If Turkey wants a go at it, fine, but the package doesn't make sense.

The plane won't be ready for another 10 years and that is with the f110 engines. The tf35000 isn't guaranteed and wars like Ukraine show that warfare is rapidly changing. I am not even talking about the nepotism that has already rusted the defense industry and the very low funding the project has.

Turkey should build a Toyota Yaris GR and not a Bugatti with 1.6tdi engine.

And what makes you think that?
TAI KAAN has approximately at least the first prototype would have 27 tons as take-off weight, if fully fueled and loaded with ammunition, at least in theory.
Both GE F-110-129 Engines each have a dry and wet thrust of 76KN/131KN.

TAI KAAN

To calculate the thrust-to-weight ratio for the TAI Kaan with two engines and a maximum takeoff weight of 27 tons, here are the details:

Given Data:

1. Thrust per engine: General Electric F110-GE-129

With afterburner: 131 kN per engine

For two engines:

Result:

The thrust-to-weight ratio of the TAI Kaan is approximately 0.98 at maximum takeoff weight with full afterburner thrust. If the aircraft operates at a lower weight (e.g., reduced fuel or fewer weapons), the ratio can exceed 1.0, improving acceleration and maneuverability.

F-22

To calculate the thrust-to-weight ratio of the F-22 Raptor when fully fueled and armed, we need the following data:

Given Data for the F-22 Raptor:

1. Engines: Pratt & Whitney F119-PW-100

Thrust per engine (with afterburner): 156 kN

Total thrust for two engines:

Result:

The F-22 Raptor has a thrust-to-weight ratio of approximately 0.84 when fully fueled and armed (at its maximum takeoff weight). This value increases significantly when the fuel load decreases or the aircraft carries fewer weapons, often exceeding 1.1 in combat configurations with partial fuel and weapon loadouts.

TAI KAAN probably uses more composite, titanium materials than the F-22, The Second KAAN Prototype will probably be somewhat smaller and more delicate, probably 6-8% Lighter then the first Prototype.
We would then be talking about a thrust ratio of 1.10/1.20 and that is more then the State of the Art.

KAAN is actually an air superiority fighter with multi-role options. But it is not a bomb truck like the F-35 which is superior against other GEN 4+ aircraft but I doubt it has a chance against a J-20 Chengdu SU-57 at least in dogfight provided the radars of both aircraft have the F-35 under control.

That(the engine) is a project we should join if possible.

 

[IC3M@N FX]

A small note about the actual Engine in TAI KAAN Its advantages and disadvantages.
Air battles are the absolute exception. In almost all missions, movement is almost exclusively subsonic. The short-term increase in performance is provided by the respective missiles. Pure super-sonic speeds beyond Mach 1.5 are only required for altitudes above 50 kft. Even several minutes in the trans-sonic range significantly reduce the remaining flight time. Today's weapons technology allows close encounters in almost all ranges. The times when an excess of speed was needed to penetrate ground-to-air defenses, see F-22, no longer exist. For this reason, super-cruise has been dispensed with for the F-35 and the focus is increasingly on the possible gain in time through optimized stealth. In the speed range beyond Mach 1.5, the respective stealth coating suffers and the costs for its maintenance increase. Today, only short-term "sprints" of Mach 1.6-1.8 are required. With controlled air intakes or a corresponding excess thrust, Mach 2 and more can be achieved, but why? A current guided missile only needs seconds to achieve this, and even an F-22 takes minutes.

Significantly more powerful engines therefore make little sense provided the design remains the same.
32000 or 35000 LBF for the owm domestic Turkish Engine for KAAN is more than enough.

If KAAN can match F35 level of speed and agility thats sufficient for us. In fact at this stage being able to reach F35 for any given cabability is more than enough for us. If we have any extras that's nice to have, but not necessary.

Well, what makes F-35 a wonder is mostly sensor fusion AFAIK. That is really hard to achieve and gets fairly arcane & esoteric for a layman to understand. I have no idea if wwe can do it or not. But mechanically, I think it will fly way higher. This has specific advantages WRT air superiority missions.

Well I think we will do fine, but F-35 can be combined with all the capabilities of aegis ship and all the US satellites, uavs etc. as well. Near our borders we should have pretty good coverage from all sort of stuff like HAKIM and what not, and the actual sensors we can put on KAAN i am confident as well. The bigger bottleneck would be software, datalinks and overall processing power ( because you would probably need to transmit parts of data to central server to process and spread to rest of network for maximum usefulness, a lot of money) and also on board processing and transmission to nearby assets of collected useful data. You need to create libraries from that data and classify them accurately, stuff like signal data from enemy radars... and then you need to then deliver the updated software or parameters to other assets in the field, can that be real time or would that require going back to base etc

 

[Iskander]

Thank you for your answer. No, I had no other goal. This question had been in my mind for a long time. So I decided to ask it on the forum.
As you can see, I haven't written a single sentence about Turkey's domestic policy for a whole year. Except for one or two compliments to Erdogan. And I don't discuss religious issues.
Only after reading your answer did I realize how tactless and inappropriate my question was.
Yes, I would also like to delete my previous post.
Sorry.

Did you know that Kaan is 10 times less visible on radar (rcs) than F-35.

this is not a scientific paper. these losers are out on twitter doing KAAN propaganda all day. how do they know the RCS of KAAN or F35 or KIZILELMA? what do they know about the applied RAM materials and their efficacy? it's just bunch of assumption made in favor of KAAN.

besides, even in their pseudo-scientific paper, F35 has lower RCS than KAAN.

They actually address all those questions in the paper with quite some detail. And when they make assumptions, they make them explicitly against Kaan to be conservative.

You can still disagree with them of course but it's not fair to disagree without reading the paper.

F22 has a ttw exceeding 1 at all times. The fact that you brought up su57 is a complete joke. j20 has been produced since 2009 with almost similar ttw as f22. MMU with own engines will probably be somewhere around 2040 and thats IF its succesful. My comment wasn't just about the weird ratios of size/weight and engines but also about nepotism reaching tusas/tai aswell. Everyone seems to get annoyed at me for saying something they dont wanna hear. It needs to be said and adjust YOUR expections accordingly. The fact that Mahmut Aksit is trying to downplay the expections says enough. MMU with f110 will be the final package. Buraya yazdim.

there is no detail on the paper. it is assumption over assumption over assumption.

A mechanical engineer is writing a paper on RCS? with no background whatsoever. written in poor English with large fonts to pamper KAAN. The calculations @Afif makes about radars are much more in-depth than this paper.

PS: I read the paper
