Turkish gas turbine engines to be the main power source for other Muslim states

[UzaySan]

Turkey needs to research and develop a materials catalogue before the steps to a jet engine can be climbed. Turkey can do it, but will need full and steady government support for 5(min) years...

Fan: Aluminum, titanium, stainless steel or Composite
Compressor: Nickel-, cobalt-, or iron-based alloys. Additive are aluminum and/or titanium, chromium, as well as rare earth elements like yttrium.
Combustion chamber: Superalloys with refractory metals such as tungsten, molybdenum, niobium, tantalum. Ceramics and ceramic-metal mixes.
Turbine: Nickel-based superalloy, outside air is circulated through channels inside of the turbine blades. For lower pressure turbine blades iron-based superalloy or even stainless steel. The metals used for turbine blades are often grown as a single crystal.
Exhaust nozzle: Nickel Inconel and stainless steel alloys.
Casing: Aluminum or polymer matrix materials.

your wish come true!!

believe they are paying rr to help them.

So, you are a believer ?

Impressive super alloy component and manufacturing process R&D programs...

İnci Project: Manufacturing capability domestically for the titanium alloy parts needed in air platforms through precision casting method.

Yakut Project: Project aims at acquisition of the Metal Powder Laser Melting (LAM) process as well as the process modeling capability for manufacturing of functional parts that have advanced mechanical features and can operate under challenging conditions such as high pressure and temperature differences in aircraft engines. Accordingly, under the project, the combustor component of the TJ90 turbojet engines, which consists of 9 sub-components, will be manufactured from UNS N06625 nickel super alloy material in one piece by using additive manufacturing method in a way to meet the mechanical requirements.

Through the know-how and experience to be gained with the YAKUT Project, it is aimed for TEI to become a main engine manufacturer that is capable of manufacturing parts by using additive manufacturing methods in its own engines in the long term.

The Dilek Project: backed up by the Undersecretariat for Defense Industries, is carried out by TAI and TEI in collaboration with the aim of developing superplastic forming process for titanium alloys which are used in both platform and engine applications in aviation industry, and as a result reducing dependence on foreign sources.

Müge Project: The purpose of program is to develop Magnesium Alloy Casting technology.

Dinç Project: 240t melting capacity aviation quality stainless steel and nickel-based alloys required to be used in aerospace platforms for the defense industry and civil purposes.

The Atom project: This program aims to develop nickel metal powder suitable for layered manufacturing for aerospace applications

The Elektron Project: Development of a titanium layer process using the Electron Beam Melting (EBM) method.

The Ayna Project: Development of new generation Aluminum alloy development

Turkiye is certainly preparing to run in defense and technology field. The impressive research and development programs are following one and other. Some of them are very special and rare technologies or production processes that will leap Turkiye into a high league.
The character, soul, nationalistic feelings and ambitious of this nation has never came to a full stop in the course of time. It is not important How big difficulties we have faced in history. Turks were/are always like the eagles who likes flying high but Slaves are already doing slavery with a big pleasure in this region who are busy to satisfy their masters.

TEI designed 9 stage compressor providing same press/airflow ratio with original HP compressor with 10 stage designed by GE.

TEI designed combustion chamber reached %98+ Combustion efficiency in trials. That is a good indication for compressors and fuel injection working efficienctly to mix optimum amount of air/fuel particulars (1/14) in chamber.

TEI is working on advanced blades cooling technology to minimize the maintenance costs, while improving the efficiency and reliability of national gas turbine engines.

Nickel alloy blades melt 1450 degree temperature but turbine heats around 1700 degrees. This means the blades operate in an environment several hundreds of degrees hotter than the melting point of the nickel alloy. To stop them melting, the metal must be cooled. This is done via two mechanisms: the blades are coated with a low-conductivity ceramic and they are supported with a complex structure of internal channels.

You can see the single crystal blade produced by TEI and domestic partners. Single crystal blades are used on turbine and compressors.

Turbines are the hottest and most dynamic place (1700 degree) of engines so blades must be produced with a material which will be resistant to such an high temperatures. Nickel alloy is the best material to apply for solving this problem. Compared to steel (up to 450-500 degree melting point), Nickel melts around 1450 degree temperature and more resistant to corrosion.

Other big problem inside the turbine is the retaining the strength level of blades. Steel, even Titanium drop off its strength level as you reach %40-50 of their melting points but Nickel alloy retain its strength up to %85 of its melting point. In turbine blades, Nickels combined with Aluminium to imprpve its strength on even higher temperatures.

This magical alloy for turbine blades have been manufactured with additive manufacturing method by
TEI.

The first FBS module manufactured with titanium moulding process has been seen on image.

Blade Repairing with laser cladding technology is being developed for gas turbine engines.

One thing that I found fascinating was that Turkish Engineers took a GE engine which had 10 compression stages, modified 9 stages to where the 10th stage was not necessary and was removed. A GE engine modified by Turks with 9 stages outputted same power and efficiency, with weight savings.

This is how we'll develop our jet engines, take existing technology, understand it, modify it, improve it, develop new technology. - We are young to this area, we can take risks with new production methods and technologies whereas the established manufacturers rather not.

So does this mean we can expect first prototypes in coming years?

Qualification of domestic turbojet engine KTJ-32 which is going to replace French TRI-40 in Atmaca and SOM cruise missile family, have been commenced. Serial production will be commenced after qualification phase passed.

Kale commenced development of a new turbojet engine with a thrust of 3,5kN and has capability of burning around 60 minutes. This engine will make an average cruise missile to carry around 800-1000km. Gezgin missile will have a similar range scale at block-1 variant.

Baykar Makina General Manager, Haluk Bayraktar, revealed that the AKINCI (Raider) attack UAS (aka UCAV) prototypes will initially be powered by a pair of the enhanced variant of TEI’s PD170 turbodiesel engine, uprated to 220 hp and dubbed the PD220. Developed by TEI for the ANKA MALE UAV, the PD170 develops 120hp at up to 30,000ft and 170hp at up to 20,000 feet. According to TEI, it can be uprated to 220hp with only minor modifications. The uprated engine is currently undergoing bench testing, according to Mr Bayraktar, and is believed to be the preferred option for accelerating the AKINCI ground and flight test campaign, until the 550hp engine, for which the UAS was originally developed, can be locally developed.

Pd-170

It is expected that Five blade propeller powered by 550hp TEI turboprop for Akinci will catch the serial production. Until that time, Domestic twin PD-220 (220hp)engine will power up the 5+ tons monster for trials.

SOM Series of Cruise Missiles required an Indigenous engine as Foreign (French) Engines were unreliable due to political interests. So, a tender for an engine to be developed with national means was started with a R&D Government grant of $25mil and $25mil from Kale Aeros Pocket, Kale Aero won the tender and commenced development.

The Tender called for engine to have operational time of 30 mins, however Kale Aero developed the 50kg engine with 5 hours operational time before degradation.
Developing such an engine first time and pushing limits isn't without it's hazards, during development 5 prototype engines were damaged beyond repair.

Kale Aero hopes to further develop engine to have greater operational time and to be used in UAVs and as APUs on larger aircraft.
