since they specifically utter "early tests" for 2026, I assume it won't be a fully built engine but some modular tests to validate their assumptions before committing to a prototype.

 

[Sanchez]

Integration to Kaan starting in 2032 means Kaan won't be delivered with TF35000 in 2032.

 

[Ripley]

Integration to Kaan starting in 2032 means Kaan won't be delivered with TF35000 in 2032.

And let’s not forget that if we take his words literally, then by integration they mean just installing the engine, introducing the engine to the plane. In such case, a production line plane will be even beyond 2032.

 

[Sanchez]

But then how come that Indonesia will get all 48 KAANs in 10 years with TF35000?

We don't know when the contract starts.

@Sanchez

I think it gets lost in translation and he's not talking about 120 months starting. If he is, that means they accepted paying very heavy fines in the long term to get a partner now; that'd be dumb.

I think he's talking about solidifying the MoU to a contract in as little time as "1.5 months". But I believe delivery schedule will start with Indonesia paying the first installment and then it will go on for 120 months. We don't know when did Indonesia paid or will pay the first installment.

I am a bit disappointed, I was expecting to see of cavitation torpedo on IDEF.

There is an alternative kara akya is loading……..

What?

Wrong thread, maybe

If you are talking about parts Q/C tests, that is an issue that they should be doing now. They have come to a stage where they are ready to build a prototype. In virtual world and in computer drawings they have an engine with each part to be produced already specified to the quality level they demand off of it.
Early test of an engine has to be a test on a complete engine.
Say they are aiming for the engine’s fan to rotate at 4000 to 5000rpm and LP spool to spin at 12000 to 15000rpm and HP spool to spin more than 20000rpm; they would first run it at very low rpm levels and check the performance and wear and tear on parts. Accordingly new parts replace sub par units. When the engine is responding within a given tolerance level then the so called first ignition is made. That is when the engine is pushed to its optimum available rpm. At least that is my understanding.
I can’t imagine any other way an early test can be done on an engine. The engine has to work as a whole to be tested. You can’t test individual parts of a turbofan if the engine is not working.

i am speaking of component level testing of different subassemblies. there could be specialized testing equipment and rigs to get data from these modules without building a complete engine.

but this is a topic i'm not really well versed. Maybe @Nilgiri can weigh in?

 

[Zafer]

Starter system, fuel delivery system, electric power generating system, lubrication system are the main subsystems that can be independently tested without igniting the engine.

And this one has cavitation propulsion?

 

[zio]

And this one has cavitation propulsion?

I do not think so but may be a bigger,longer,heavier,akya for long endurance.There is no limitation of subs torpedo tubes,but they may go for exactly the same akya totpedo,its not clear.

The plan was to build the prototype in 2026, followed by integrating just one engine into the KAAN in 2028/2029 as a test. The goal was to have a fully domestic fighter with a domestic engine for production by 2032.

Has that changed, or are these people just reading too much into it?

The time table of the project moves back and forth a lot tbh. So, I’d read that as changes and rearrangements as the situation requires them. Honestly, there might have been moments where some phase(s) had been rushed due to political considerations but not project demolishing proportions imho.

The production line aircraft with fully developed, matured satisfactory production quantities of domestic engine(s), however, .. Now that’s another ball game.

 

[TheInsider]

I double checked my sources, and they insist that the first fighter with the national engine will be delivered in 2032-2033 (2032 at the earliest). At this point, we should wait and see how the project unfolds.

 

[Saithan]

I believe the sales contract of KAAN is worse than T129 to Pakistan. I feel sorry for Indonesia, they should have gone with F16 or EF. But if they can use the deal to get better offers from others I hope they will get them.

 

[Merzifonlu]

At this point, we should wait and see how the project unfolds.

In this case, your sources contradict @orko_8. I assume both are correct.

I think things will unfold as follows: 20 Unit Block-10 Kaans will be produced in 2029, but they won't be equipped with the F110 as expected. Instead, they'll be equipped with the immature TF35000.

In 2032, the mature TF35000 engine will be officially integrated into the Kaan. Of course, this integration will only be on paper, as the TF35000 engine will have already flown on the Kaan between 2029 and 2032.

 

[Saithan]

Why would they wait with conducting tests at the same time? One engine is known and has a proven track record, another is new unproven. Isn't it better to test the shit out of KAAN with the GE engine and find out what it's capable of than try to do it at the same time ? You'd have time to test the limitations of structure/design with the power GE engine can give the design.

Then you try to do the same with our own engine and hope it won't crash.
