Just search "jet engine design stock footage" and you'll find literally thousands of images and videos, which was clearly what TRMotor did with that unnecessary tweet. Here are 3 results, you can sift through them if you want to find the footage they used lol

TR MOTOR obviously promise to make every aviation turbine engine the nation will need in the coming several decades, this is what matters.

There is nothing wrong with a video VISUALIZING types of engines they are already developing or soon will develop.

Do you realize that they could only identify some engines after a reverse image search, so they are using some generic engine visuals, nothing more.

This was an AD? What were they advertising and for which potential buyers?
I thought it was just an ordinary happy new year Türkiye tweet. Chill people, for a second if you can. They are just starting at this and it is new year.

Here is an actual Apple Ad. Steve jobs holding an apple seemingly compares himself with images of great leaders and thinkers. How did that end? Didn't he deliver?

I am not saying TRMOTOR tweet was as revolutionary or it was even an AD, but it doesn't have to be. It is just a visualization of future product lines. How hard it is to get that?

It looks like the Indians ditched Rolls-Royce and Safran for engine development.

All US clearances received: HAL, GE to produce jet engines for LCA Mark2, AMCA fighter jets in India

"The engines of LCA Mark 2 and the first two squadrons of the indigenous Advanced Medium Combat Aircraft would be produced within the country together by American GE and Hindustan Aeronautics Limited as all the clearances have been received from the US," DRDO chief Dr Samir V Kamat told ANI...

Rolls Royce offered them IP rights, technology transfer, and Indian production.
But they went along with GE.

Maybe they'll feel the pressure and offer us a similar deal because they seem to be having some financial difficulties.

Although it could be a pipe dream.

GE F414 was selected for Tejas Mk2 (over EJ200) many years ago. When you talk of RR and Safran, I think you are referring to the 110+kN engine needed for AMCA Mk2. As far as I know, that is intended to be developed with Safran. I imagine that negotiations over the specification and cost are ongoing.

I think that RR suffered severely from airliners being grounded during the Covid pandemic. Many RR engines on airliners involve 'power by the hour' deals. No hours flown meant no income to RR.

Did TSK have any propulsion project for reaching heights above 75k feet ?

High-Altitude, Long-Endurance UAVs
Substantial efforts are under way to develop propulsion technologies for HALE surveillance and communications-relay missions. The mission objectives for HALE UAVs are to operate at as high an altitude as possible to maximize the geographic coverage of sensors and communications. High altitude can also be an important contributor to survivability because high altitude reduces the aircraft’s vulnerability to ground-to-air and air-to-air missiles. However, to be entirely safe from many widely deployed threats, operating altitudes must be above 75,000 or even 85,000 feet. These altitudes cannot be routinely reached with current propulsion technology.

At an altitude above 75,000 feet, there is very little air (the air density at 80,000 feet is only 3 percent of the density at sea level), which affects air-breathing fueled propulsion systems in two fundamental ways. First, engine weight is inherently higher. The fuel required to produce a unit of thrust per time is the same at high altitudes as it is at low altitudes, but the fuel-to-air ratio is fixed by the chemistry of combustion. As a result, the required mass flow rate of air is set by the power required.

Second, the large compression ratios required for gas turbines (additional compressor stages must be added), piston engines, and fuel cells (which require several stages of turbocharging) result in weight and drag penalties. The additional compression requirement significantly increases the weight of high-altitude propulsion systems. Because the compression process increases the temperature as well as the air pressure, the required pressure ratios result in temperatures that are too high for current technology. Thus, coolers (heat exchangers) must be added to the compression system. The weight and drag penalties of these heat exchangers are exacerbated by the very low ambient air density. High-altitude aircraft under development for NASA, which use piston engines, have more area and drag associated with heat exchangers than for the wings. The increased weight and drag of heat exchangers with altitude limit the operating altitude of these designs (Drela, 1996).

Looking good, really looking good. People can criticize and talk about the delays as much as they want, but this is a stunning view of a running Turkish tank engine that most of us did not thought of 10/15 years ago.

TEI:

"3 R&D projects we carried out under the auspices of Defense Industry were signed.

With the SICIM, EUTECTIC and AMETHYST projects, which aim to develop critical materials used in aviation engines, we will implement national solutions containing advanced technology, which will reduce foreign dependency on materials and material processes used in aviation engines."

Yes, very nice, but is it possible to show which components of an engine could potentially be made with these technologies ?

Perhaps someone who knows could snapshot a engine and color the components in three different colors.

It would go a long way for people to understand these technologies contribution.

SİCİM is arguably the most important project of SSB at the moment. Silicon carbide (SiC) fibers will be developed in the scope of SİCİM project. Those fibers will be used to produce hot-section turbine blades and replace single-crystal superalloys. Phase 1 of the project covers the production of high-quality SiC that can be used to produce SiC fibers thinner than a strand of human hair and prove that those fibers have required mechanical and thermal characteristics. Phase 2 will involve coming up with a serial production process and product standardization.
Those thin fibers are coated with a very special coating and woven/embedded together inside a SiC matrix to create a turbine blade that is as tough as a single crystal superalloy blade but not brittle like ceramic. The end product has only 1/3 weight of a single-crystal superalloy blade and can withstand temperatures a lot higher than single-crystal blades. Low blade weight means lower centrifugal forces which means thinner shafts etc. A big reduction in total engine weight and higher thrust-to-weight ratio. Higher operating temperatures mean higher thrust and more efficiency/lower fuel consumption. CMC is the next big thing in turbines and anyone who masters the tech will make huge money. Currently, GE is leading followed by IHI and TEI is in a good position. If SİCİM is announced as a project it means it already passed some milestones. TEI was subsidizing Phd thesis and it seems the results are good so this official project is launched.

AMETİST project is for the cold section. TEI wants to produce MMC (Metal Matrix Composite) parts for the cold section of the engine by using additive manufacturing so TEI is developing a melting process for metal dust by using a laser. This is a process development project directly related to production.

ÖTEKTİK is another CMC project for the hot section but it is for the fixed parts like combustion chambers, exhaust mixers etc.

Great news all around. Hope we'll see similar good news on rotating detonation engine projects!

One of the most informative interviews about the state of Turkish missile propulsion engines and Kale Arge.

Land based anti-ship missile engine for Atmaca, KTJ-3700 is still a prototype and going through lab tests.

Arat apparently would be similar to KTJ-3700 with higher compression. I was hoping larger diameter and much higher thrust to support a big 1 ton warhead and 1000+km range. But they said they are making the engines able to run much longer durations. So there is still hope for my 1000+km, nuclear capable Gezgin cruise missile that could hit anywhere in Israel with overwhelming surface-hugging barrages. I am not sure we will ever be able to produce those in numbers to overwhelm Israel's intense air defenses though. That is a necessity to kill decades long active Greater Israel project CIA, Neo-cons have started with invasion of Iraq & Syria.

Tomahawk like more fuel efficient small turbofan engine for longer ranges is still in concept stage. They have no small turbofan engines to copy from like they did with French TRI-40. So I am less hopeful about that.

Good post and nice video, but please don't derail the thread with speculation about who it will be used against. Feel free to do that in an appropriate thread. This thread is about the development of our propulsion systems and nothing else.
