TR Propulsion Systems

Does anyone know how the blades are prevented from sliding laterally and potentially falling from these disks?

It is basicly has a locking mechanism, this video talks about it among many other intersting subjects related to Turbuine blades.

So now we have a name for the indigenous turbofan for Gezgin cruise missile.
I had also heard the name TJ1600 as a jet engine but it is not mentioned in other news.
However in one post TAI mentioned the number 34 as the number of projects they worked on. Which I believe includes several other configurations that were worked on in the process of developing the TS1400 turboshaft engine. If they worked on enough many configurations of engines that will lend itself to more exotic applications like VTOL propulsion can be derived from those engines. An axial flow turboshaft can be turned into a discrete fan turbofan engine with jet exhaust in the back. Kind of an extended shaft geared turbofan or the configuration that is on the F35B. I don't see why not.

A smaller engine than a full size fighter jet engine like the TS1500 or TS300 would be a good testbed to work on to experiment towards exotic applications due to its smaller size which will mean easier handling. A VTOL UCAV derived from such an engine could be the Turkish version of an F35B style fighter. Giving credit to Selçuk Bayraktar who alleged years ago that the F35 will be the last of the manned fighters.

In many instances Mahmut Aksit has mentioned that with the success attained when making the ts1400 engine, they will be able to develop a turbofan engine in the future. He has also said in various videos that there is work being carried out on the engine for TFX.
But we have to be aware of the fact that even a very small part that needs to be sourced from another country could be subject to delays or even secret embargoes if it were known it was for our new engine. So secrecy is of paramount importance.
In the meantime we can only theorise and contemplate about what is being done.
Come on 2028! Hurry up!

Interesting and unexpected company I found here in the list of the fastest growing companies from 2016-2018 on place 18:

18. Kale Pratt & Whitney Uçak Motor Sanayi A.Ş.

Türkiye'nin en hızlı büyüyen şirketleri belli oldu

TOBB, Türkiye'nin 2016-2018 yıllarında en hızlı büyüyen 100 şirketini açıkladı.

Kale/P&W 51/49 partnership is producing parts for the f35 engine. It is a shame that this privately owned partnership is more quick profit orientated than future investment orientated like TEI. Hence the lack of mentionable indigenous engine development ! But this could hopefully change once the ktj3200 becomes a success and they get more state based contracts.

Thanks to @Zafer

This might be totaly experimental stuff nonetheless It is exciting

From 2018 TEI magazine

Under "Original Engine development programs"

"...Beside, Syncronized Engineering work is contuined, supported by Production engineering department's Design support under Turboshaft, TJ1600 and DP370 projects."

https://www.tei.com.tr/uploads/docs/tei-post/1562587542_tei-post134.pdf

From CV of an Engineer from TEI

So There is indeed Turbojet Engine work in TEI with TJ1600 name.

It is highly likely that the engine in question is this engine; but no specs mentioned.

1600hp equals around 3800lbf dry thrust. It will be in same league with Ivchenko Process Al-25TLT (3790lbf max)

Goksungur engine?

Highly likely.
This can put Göksungur to the top of the food chain of Turkish UAVs but we don't have much supporting evidence.

But isn't it a TJ and not a TS and thus the figure corresponds with thrust instead of hp?

But what is DP37?

https://tr.linkedin.com/in/%C3%B6zkan-yildiz-8a1497136

His CV says experience on DP8-22-37 manufacturing. Evalutionary PD series?

 

[Yasar_TR]

As it is 1600 HP and TJ as you say ; this is a thrust HP. Not Shaft HP!
According to Cabatli-53’s above share, two of these engines with this sort of dry thrust, can easily power a subsonic Hurjet or a supersonic Goksungur.

But doesn't TEI use the number after the 'TJ' to indicate the thrust in pounds? For example: TEI TJ300 has 300 pounds of thrust.

This engine seems to have been developed as a side product to the TS1400 engine and probably has the same BHP rating as its turboshaft equivalent. I have seen this engine at one of the trade-shows and it does have a similar combustor size to the TS1400 engine.

Hmm, I'll have to take your word for it then, but I am not entirely convinced.

It also appeared at the same time as TS1400 appeared.
