No it can not. But it can operate for 17 hours without breaking. An air vehicle that is powered by one of these engines can not possibly carry enough fuel to fuel it for more than a couple hours let alone 17.

Yes, the endurance 'service life' is up to 17 hours.

Why waste resources to build an engine capable to run 17 hrs when the need is 2hrs? Surely they could make it a lot cheaper if they reduced its quality

This engine is not just for the missiles,it can be used on target drones.Some target drones are reusable,so you can use it many times,very cost effective approach.The other platform could be kamikaze drones with passif radar emitting,so you can use it many hours over radar sites to shot down of it,and it will be fast to heat radar sites,and give little time to hunt it.Thats my specualtion.

More then US$50 million has been spent on the design and development of the KTJ-3200. It is also optimised for unmanned platforms, target aircraft... Which is why KTJ-3200 is capable of flying up to 17 hours.

it drinks fuel like a hungry hippo. It doesn’t make sense to use this engine for UAVs or target drones. We a missing a few pieces here to explain what is really going on

When making an engine like this you don't gauge the engine quality by dialing in hours, you apply certain ttechnologies and get an acceptable endurance. Probably the highest stressed components of the engine which are the bearings can only last 17 hours and this determines the engine life. So, could other elements be made cheaper now that the engine can only last so much, I believe their quality effects engine fuel burn and speed and should not be made to a poorer quality standard.

ÇAKIR Füzesinin Motoru KTJ-1750'nin Test Görüntüleri

Kale Arge tarafından ÇAKIR Seyir Füzesi için geliştirilen KTJ-1750 Turbojet Motoru, tüm alt sistemleriyle birlikte yapılan son testi sıfır hatayla tamamladı.

KTJ1750 test video clearly shows above 50000RPM speed. Thanks to it’s small diameter the Engine turbine can achieve these high rotational speeds. They plan to deliver the first prototype to Roketsan next week.
It seems that Kale now are very good and capable at small turbine engine manufacturing and the long development experience they have had with the KTJ3200 has paid off in the end.

The second prototype of the TEI-TS1400 Turboshaft Engine Accessory Gear Box (ADK), designed and produced by Alp Aviation and to be used in Gökbey Helicopter, was delivered to TEI with a ceremony held at Alp Aviation facilities.

Internal Layout of TEI-TF6000, a Low Bypass Turbofan Engine​

​

November 15, 2022

The TEI-TF6000 is a Turbofan Engine with a total length of 2,250mm, a width of 860mm, and a height of 1,100mm. According to the product brochure, it has a Specific Fuel Consumption value of 0.70 (lbf/lbf.s) and a bypass rate of 1.08 (SLS, ISA).
There is a 2-stage axial fan at the front of the engine (it rotates at the same speed as the Low-Pressure Turbine). Behind the axial fan are two separate air ducts, one for the air bypassing the engine core (bypass duct) and another for the air going to the core through the high-pressure compressor. The TEI-TF6000 engine is designed to produce a total of 6,000 lbf dry thrust, approximately 4,000 lbf with the core engine, and 2,000 lbf with the bypass stream. However, like the TEI-TS1400 turboshaft engine, the TEI-TF6000 is expected to generate slightly higher thrust than the initially designed level.

The low bypass TEI-TF6000 turbofan engine has a 6-stage axial compressor behind the 2-stage axial fan. Both fan and compressor stages are manufactured with 'blisk' technology. In other words, instead of having the blades manufactured separately and stacked on a disc, the compressor blades and the rotor disk are manufactured as a single piece.

The combustion chamber (through-flow type) is located behind the compressor stages. The pressurized air from the compressor is mixed with fuel in the combustion chamber, and the hot exhaust gas is later fed into the turbine, causing the turbine blades to rotate. Therefore, turbine blades must be manufactured with single-crystal technology to withstand high-pressure exhaust gas and operate at very high temperatures. TF6000 has a 1-stage High-Pressure Turbine (HPT) and a 1-stage Low-Pressure Turbine (LPT) behind the combustion chamber. The HP turbine rotates the compressor while the LP turbine rotates the fan. The hot air from the turbine is then mixed with the air from the bypass duct and is released from the nozzle at the back.

The Nozzle Guide Vanes (NVG) see the highest temperatures among the engine parts since the hot gases from the combustion chamber pass through them. Cooling of NGVs is extremely important to prevent the metal from melting and maintain its operating temperature. The NVGs are usually of hollow form and cooled by passing compressor delivery air through them to reduce the effects of high thermal stresses.

Designed in a modular way, the TEI-TF6000 turbofan engine also has an oil tank. It has a reserve oil level for the lubrication of the bearings. The oil and fuel pumps work with a starter generator connected to the gearbox.

While titanium is used in the cold section of the TEI-TF6000 engine (fan and compressor stages at the front), Nickel superalloy is used in the hot section (combustion chamber and turbine stages at the rear). The metal parts in the hot section are also covered with a thermal barrier coating made of ceramic.

TEI-TF6000 also features labyrinth seals at the back so that the circulating air inside the engine, which also cools the parts, does not escape outside. The exhaust is the last section of the engine. TEI continues to work on the afterburner design to be added behind the exhaust section. Thus, the afterburner will be developed and produced for the first time in our country for the TEI-TF6000 engine.

The production of parts for the TEI-TF6000 engine prototype has already started, and assembly work is expected to begin in the first half of 2023.

It is stated that the TEI-TF6000 can be converted into a turbofan engine comparable to F110-GE-129 by replacing the HP fan and LP turbine and rescaling the compressor, combustion chamber, and HP turbine. In our interview at the first day edition of SAHA EXPO Daily, President & CEO of TEI Prof. Mahmut AKŞİT also pointed out that if the radii of the relevant parts in the engine are expanded by 15 cm, the TEI-TF6000 can be converted into a turbofan engine similar to the F110-GE-129 which will also be used on MMU prototypes.

Motor sich has been hit multiple times by the Russia. I hope we anticipated and took precautions prior this attack. Because this was no surprise

I’d have liked it if tumosan was more active in delivery to defense industry.

ULAQ to use diesel engine developed by Tumosan.

So what is the status regarding BATU engine ?

 

[Radonsider]

Is there any engine that can produce more than 10000lbf thrust tei is working on right now?

Not TEI but subsidiary of TEI (TRMotor) is working on a 29k-35k Lbf engine, probably based on TF-6000 design

 

[TheInsider]

There is good news about the BATU powerpack. The engine satisfied all of the requirements on the bench runs. Bench tests of the transmission progressed a lot and coupled tests are expected to start. This is the last step before integrating the powerpack prototype into the tank. It seems that the target date of 2024 will be realized.

When do these engines suppose to finish?

When do these engines suppose to finish?

The engines themselves are ready but the problem is in the transmission system to be coupled with these systems. BMC Power had difficulty with such transmissions but recent TheInsider post indicates that the transmission itself is near completion. Probably the powerpack (engine + transmission) will be integrated into the Altay by 2024

BMC Power has been doing a lot of good stuff lately
Hopefully Turkey will finally gain independence from Western embargoes on land platforms; particularly, filthy Germany
