About the „ACE“ on FCAS

„The variable cycle engine (VCE) architecture allows flexible adaptation to operational requirements, resulting in high specific thrust and low fuel consumption. The VCE architecture differs from conventional drive systems primarily by an adjustment mechanism and an additional flow channel. With the help of the adjustment mechanism, the engine control regulates how much sucked-in air flows through the respective flow channels and the core engine. Thanks to this variable distribution, the thermodynamic cycle of the engine can be optimally adapted to the most common operating requirements and thus guarantees a high specific thrust and low fuel consumption.“

There is no FCAS and there is also no French ACE.

According to news coming in from media sources RR have not really given up on an Adaptive Cycle Engine. In fact it has it in its programme going forward. But seeing what has happened with F35 whilst being part of the initial development, and what problems it is still living with, they have decided to put it as a retro fitting idea for next iteration of the Tempest. For the first iteration they will play it safe.

Integrating an ACE to a plane is not an easy task. This is a totally new technology that will have to be integrated in to a platform that has been primarily designed to be flown with turbofan engines.

Integrating an adaptive cycle engine (ACE) into a jet aircraft is difficult due to the engine's inherent design complexity. ACE features unique operational components such as Core-Driven Fan Stages and mode selection valves with variable area bypass injectors.
It is all very well firing and testing these engines on their own. But having to integrate them to a flying jet fighter in real life is another story. Ensuring all components are performance-matched across the entire flight envelope for a plane is a major engineering challenge and improper matching can lead to instability and/or efficiency problems.
Thermal management of the ACE’s third stream in to the plane’s specific architecture is a challenge in it’s own right. Engine's size, shape, and airflow requirements differ from conventional engines and will require airframe modifications not normally expected. Ace’s demand for airflow, changes significantly across modes and will require inlet and exhaust matching adjustments not found in conventional engines. A plane flying with them has to be adjusted to accommodate it all, seamlessly.

Taking all this in to consideration, rather than half flying a plane with an ACE, RR is going along with a safer route of a turbofan that is few steps ahead of it’s competitors as turbofans go. Especially the timeline they they have set for themselves it is the logical route.

Tempest will have special composite structural surfaces that will rely on dynamic stealth rather than coating. It will rely on heavy and powerful EW for stealth as well as its shape without detracting from agility and manoeuvrability. According to a BAE official it will be the first UK jet fighter that could fly transatlantic without needing refuelling. It should be able to carry up to 10000lb of munitions.

Here is an interesting article on 6th gen jets

What makes a fighter jet 'sixth gen' and why it matters

Sixth-gen fighters are being built for the wars of the future, wars that will rely more on stealth, sensors, and long-range weapons.

Turkey denies claims Erdoğan was misinformed on KAAN fighter jet engine - Turkish Minute

Turkey’s presidential communications office on Wednesday rejected claims that President Recep Tayyip Erdoğan was not informed about US involvement in the engine program for the country’s new KAAN fifth-generation fighter jets, calling the reports “a clear act of disinformation.”

www.turkishminute.com

This is an interesting article on the latest situation regarding KAAN engine.

The last sentence is of significant importance when you think of previous posts here about the KAAN engine consortium and Starmer’s latest Tusas/Kaan visit. Plus our top brass being bullish about the tf35000 timeline.

“The $1.18 billion project includes collaboration with BAE Systems and Rolls-Royce for engine development, according to the SSB.”

At the same time, FM Fidan’s latest statements regarding the CAATSA being lifted soon is significant and meaningful, as it will pave the way for f110 engines‘ arrival for serial production.

In retrospect KF-21 might have been a better option than F-35 for Canada. In view of what has happened, it might have been a better option than F-35 for Turkiye, too.

Eurofighter is better than current KF-21. Why even compare KF-21 with F-35?

As you say better than “current” KF-21.
In fact KF-21 is what f35 should have been. A twin engined fighter. For future it needs IWBs and two stealthy indigenous engines and a more powerful domestic Aesa radar with may be a bit more power than the one being produced by Hanwha using ~1000 GaN TR modules. (It needs more than 1500 TR modules, unless KF-21’s radome is the limiting factor for a bigger radar)

In time KF-21 may become what F35 couldn’t. So it is correct to compare it to F35.

The only big advantage of Typhoon is the fact that it is in full production swing and it has established itself. Also the incoming new tranche 4 and 5 versions will have very powerful Aesa radars with extensive EW capabilities. Currently their RCS values are very close to each other. But that will change for the benefit of the Korean Jet as it is evolving. KF-21 has all the necessary geometry in place for a stealth 5th generation fighter jet. It can only get better. Typhoon can’t get any better. It is at the limit of it’s design.

Koreans are going through the strides like we are with KAAN. Except we are a little behind. Also they are putting their bets on the current KF-21 more than we are on Kaan block 10. Our aim is block 20 and more with indigenous engines. We are a bit luckier as the design of KAAN allows IWBs and has a bigger radome.

Waiting for Kaan to come online KE and Anka3 should be paired with Hürjet and F16 bringing a degree of stealthiness to the TurAF assets and can even be offered to other users. This can be achieved 2-3 years before Kaan joins the ranks.

In reality, it could be very wise for some Western countries to join some sort of development of KAAN. That would be the quickest and cheapest way to somewhat close the gap to USA and China and even Russia. But I am not holding my breath.
Someone can't expect from these kinds of the politicians to make rational decision.
Even this maniacal procurement of the weapons, show that they have no pragmatic decisions making abilities. Just panic buying

 

[Spitfire9]

The France/Germany/Spain FCAS programme is reported to be suffering from problems regarding French/German co-operation. If it does not go ahead, might Spain be able to contribute usefully to KAAN (I don't just mean funding) and vice versa? Could there be some kind of synergy? I recall that Spain worked on developing a vectored thrust system for the EJ200 engine for Eurofighter.

Bro, that is a a far fetched wish if you ask me. Not all Western countries are humble enough and have the humility to work with a “Muslim” and supposedly “inferior in technology” country like Turkey. Not every western country is a Spain!
Italy has only started to work with Baykar after a de facto situation that pushed Leonardo in to partnership after Baykar’s purchase of Piaggio.

Just go online and ask Google in any which way for “best supersonic trainer jets” . You will not find Hurjet amongst them. Even Google is biased.

There are still many western technocrats that don’t believe Turkey is capable of serially building a jet fighter. Never mind a stealth jet fighter. You can not overcome this kind of bigotry over night. It will take time. Many people still don’t believe TEI can build a turbofan engine that can propel Kaan jet fighter.
When our Kaan start flying next year multiple times and finally with TF35000, then we may see more of those sceptics coming round and knocking on our doors.
