And it looks like it will be Turbojet, because in the last sentence it states "ARATJET, BIGAJET".

Turbofans are jets too

My thought was that ARAT is a Turbojet and they use ARATJET, so BiGAJET will be Turbojet too. But yeah you could be right too.

 

[Anmdt]

Turbofans are jets too

I am certain that Gezgin won't have a single version/block, Turbofan version will exist for Navy and BiGA should be the turbofan.

B i G A, what this could be ? Can't relate to anything but a small province in Marmara region. Should be something within the initials Bi and G + A. Or simply "Big Arat?"

Production plan/projection of Kale Jet engines.
Blue: Guided munitions(KGK kit, no engine)
White: Stand-off missiles (engine)
Beige: Anti-ship missiles (engine)

A production rate of over 9000 engines per year will be reached by 2032.
Kale plans to produce over 1000 engines(probably close to 1500) in 2025. (stand-off+anti-ship)
Note that Kale alone produced over 2000 KGK kits in 2023. Now we have other companies that produce guidance kits too. We have a huge production capacity.

Kale is developing Aratjet, Bigajet, and a variant of KTJ-1750 for drones. The KTJ-3200 variant for SOM is named KTJ-3200S, and the Atmaca variant is named KTJ-3200A there are also other variants for different projects.

You can read from page 65 unfortunately it is in Turkish.

Can you explain what a 'continuous wave engine' is?

Can you explain what a 'continuous wave engine' is?

https://www.eucass.eu/component/docindexer/?task=download&id=2692

Essentially it is a CRDE. Continuously Rotating Detonation engine. As the fuel is injected in to the combustion chamber in a continuous manner, the detonations are formed in a wave motion creating a CDWRE .

There is still a long way to go with this engine. We have only managed to run it for 10seconds. It needs to operate flawlessly before we can say we have “developed“ it. Nevertheless, what Tubitak has achieved is exemplary. Great step towards developing this engine. As conventional air breathing...

Can you explain what a 'continuous wave engine' is?

As I tried to explain above, the development of gas turbine engine technology is reaching it’s limits. Gas turbine engines can only operate in atmosphere. They are not very fuel efficient. At high altitudes you need turbojets, at lower altitudes you need turbofans.
A CRDE (Continuously Rotating Detonation Engine) can work in and outside of atmosphere. It is much more fuel efficient. On top of it it has potential to achieve immense amounts of thrust.
It can be used to propel space rockets or passenger planes. Or it can be used to power large ships in place of gas turbines.
Currently there are no operational engines using this technology. But the potential is great. We have joined the elite group of developers of this technology thanks to Tubitak.

Actually the beauty of this technology is that you are doing away with a lot of moving parts that a turbine engine consist of. In a CRDE what you have is an annular detonating chamber and fuel inlets. Normally There are no compressors no turbine blades that need to be made out of single crystals in a CRDE. But when there are turbines and compressors in a turbine engine that are working with a CRDE, the CRDE makes them operate more efficiently without the need for high temperatures normally needed with these engines.
A CRDE can also be incorporated in to a Tubojet Engine to render it more capable. The rotating detonation waves can also be applied in turbojet engines. Rotating detonation turbojet engine can produce a large effective thrust at low pressure ratio. This will reduce the number of compressors in conventional turbine engines and then reduce the demanding requirements of the turbine manufacturing process. The resulting combustion chamber is smaller, simpler, and of higher thrust/weight ratio. Due to the characteristic of detonation waves, the performance of such engines will be increased greatly as well.
If you check the cylindrical annular chamber in below diagram you will see that the detonation waves for different fuels give different detonation wave structures.

In order to have continuous detonation wave there are certain limitations and rules with respect to detonation chamber size and height. For example, the radial size of the chamber should not be smaller than one detonation-cell size.

This technology, theoretically, would revolutionise the ramjet engines as well.
Here is the simple set up the Chinese scientists have carried out their tests with:

Here is a cross sectional very slow motion picture taken by the French lab that carried out the tests which shows individual detonations in the combustion chamber;

TUBITAK Marmara Research Center (MAM) Hydrogen and Fuel Cell Technologies Research Group has developed Turkiye's first domestic high capacity proton exchange membrane (PEM) type electrolyzer to obtain hydrogen with 99.9 percent purity. The green hydrogen to be obtained from the PEM electrolyzer system will be used to cool the turbine generators at the EnerjiSa Natural Gas Power Plant.

Our TEI-PG50 engine, Turkey's first two-stroke gasoline aviation engine, has a 30,000 ft. Do you know that it is the world leader in its class with altitude?

Can we build with this engine cheap drone just to hunt other drones without to much money spent like iranian doing that some of their small drones aslo downed tb2 or aksungur ??

Kozan Selçuk Erkan mentioned Iranians use an off the shelf small jet engine for 358. That kind of engine is more in Kale arge's roundhouse but I may be wrong about that.

 

[Sanchez]

Do you know that it is the world leader in its class with altitude?

If I had to guess, because noone else in the world has the need for such an engine. All of the competitors of Aksungur and even Anka use turboprop engines.

358 uses a small jet engine. A killer drone with this engine would be too short of breathe.

Prof. Dr. Haluk Görgün, the President of the Defense Industry Agency, stated that Tuna, the first mass-produced domestic engine developed by BMC Power and used in tactical wheeled armored vehicles, can be used in all armored vehicles weighing 20-25 tons.

Any news about TF6000?

Any news about TF6000?

I wouldn't expect a lot of news from TF6000 while ground tests are running, which is probably a year or two at best. Last news was test were still going a couple months ago I think.

What about tf10000 though?

 

[begturan]

Generally, there is no embargo on products in the prototype phase in Turkey, whenever they want to move on to the mass production phase, problems arise in the supply of subsystems, so it is normal for us to receive news a little late about the TF6000, the local subsystems are being prepared.

If we can get the TF6000 into mass production, it will be that much easier to get the TF35000 into mass production.

 

[boredaf]

What about tf10000 though?

Probably still in design phase? I doubt they would freeze the design and start building a prototype before going through whole battery of tests with TF6000 since it'll be the basis for TF10K. That is just my guess though, because a jet engine is a very complicated challenge and as TEI president said in one interview, you can only do so much with simulations and analyses, you have to test, pick the engine apart, see what happens to this or that, put it together, test again, and again and again to be sure.
