Iranian military engine development news and updates

[TheImmortal]

Pataramesh is not a reliable source, not even a engineer just another "Panahandeh" in the west. i dont take such types very serious.

just another "Twitter expert"

i know some of the engineers from MAPNA working on the project (im following them on social media)

and in their posts they claim all PARTS tested today on the engine were made @mapna.

Patramesh is a pro-IRGC supporter and government supporter.

Lol first you say “you know” some of the MANPA engineers then backtrack and say you follow them on social media. That’s like me saying I know Elon Musk because I follow him on Twitter.

There is a difference between building PARTS for the engine to maintain it vs building the entire engine from scratch (like in case of OWJ ie reverse engineer J-79).

No plans to produce CFM-56!

Ok, MAPNA manufactures all parts and engine components of the CFM56, and claims it is not interested in producing complete engines, but this statement could only be because it does not want to jeopardize its international position by producing an unauthorized copy of the CFM56.
However, this cannot exclude that it is other industries in the Iranian aircraft engines sector that assemble the CFM56 with the components that MAPNA produces or that they transfer the know-out to make them

Owj is most advanced variant of J85 and not crude J79 series.

Latter has way more compressor stages and one more turbine.
But former has twin spool axle and annular combustor.
Hence latter is more complex, but less advanced.
Former stepping stone for FJ33 turbofan clone.
Thus creation of Jahesh became possible.
CFM-56 is certainly within Iranian capabilities.
By end of this decade we could see such produced.
Because necessary technologies have been reproduced.
All is left is to increase both scale and complexity of manufacture.

I think this is most likely. MAPNA is a quite serious international company, they don't want to be involved in any IP lawsuits.

Either way, they are making great progress in not just maintaining but producing turbofan engines.

I don’t see where they said they manufacture ALL components. Listen I would be very happy for Iran to produce this, but given how few Owj have been shown off or FJ engine it makes me doubt if MAPNA could produce this economically at scale.

So let’s say for a moment that MAPNA could manufacture CFM-56 from scratch. What is engine life? What is time to overhaul? What is cost? Can it mass produce at a economically viable cost?

CFM-56 is no easy engine to produce. France battled US on ToT. CFM-56 was made due to sensitive tech involved in F-101 that US did not want to share with France.

Owj is most advanced variant of J85 and not crude J79 series.

I misspoke as I was typing quickly on mobile while multi-tasking. Thanks for correcting me.

Which is my point exactly. I forgot which IRGC commander said that Iran reproduced F-14 engine and the F-14 flew. But yet Iran doesn’t claim to have reverse engineer F-14 engine.

Also even if you could manufacture engine, the question becomes what is the life span, engine hours, and time to overhaul compared to original. I doubt Iran’s first copy will 1:1 match of CFM-56 stats. Not even China could achieve that with its massive resources when it started mass producing jet engines back in the day

Iran has yet to unveil the capability to mass produce jet engines or even Kowsar. Everything is small scale projects or test beds.

What happened to National Helicopter project that was touted for years? What is the status of Kowsar the trainer version? Let’s see what happens with Simorgh (I-140 copy) another so called mass production effort.

MANPA is very respectable organization especially in field of gas turbines. But healthy skepticism is warranted.

I am assuming that this engine will also be tested in a facility being built by MAPNA to do full Environmental test (High and Low Temps, rain, hail, lightening..etc.)

As reported in Dec 2022:

Iran's largest aviation engine "Test Cell" launched

• Project is by MAPNA and private investors
• Capable of full environmental simulation
• only a handful of countries own such facility

چین ۱۰۰ میلیارد ریخته در این فیلد و هنوز کنترلر رو خودش نمیسازه

این فیلم میگفت ما حتی کنترلر رو هم میسازیم
ولی صبر کنید تا انبوه سازی بشه

بعد قطعاتی که چین ساخته در ۳ جی خوب کار میکنه ولی در ۸ جی مشکل داره

جزئیات کار چین هم دقیق معلوم نیست چه یرسه به ایران

Better photos of the engine during test.

 

[glablo]

Although the CFM56 is 50 years old, there are only a few countries that can independently manufacture large jet engines for passenger aircraft.
Only three countries, the U.S., Russia, and China, have independently developed such engines, and most of them are jointly developed by multiple countries.
Even China has only recently succeeded in developing the CJ-1000A after several decades of effort.
It is surprising that a country like Iran, which is completely blockaded, has succeeded in reverse engineering on its own.
At first glance, the progress may seem slow, but it is a significant enough accomplishment.

Did they really made this or they r trying to hide the fact? Bcz of patent/ copyright law and sanctions.
We know the test stand is already known product they showed earlier.

Copy rights, IP rights..Patents..none of these legal stuff is applicable to Iran...All western countries left their contracts and legal obligation to Iran when they packed and left Iran under US sanction and not UN sanction..

These countries also have blocked Iran from accessing billions of her money in their banks because of US and not UN sanctions..if they practice rules of jungle..they will be treated with the same rules.

 

[lydian fall]

Few countries in the world can make engines

Let alone jet engines

Congrats..

So the engine story is real?? Although some says false alarm, some mistake in the news. mapna themselves avoided answering directly in their twitter posst.

All I can say is what is reported and what is in the photos..but why would MAPNA build a multi million dollar test cell (the rendering of it I posted yesterday)..if there is not going to be an engine to test..why would they show an engine to the president ..Mr Sahureka2 answered your point why MAPNA avoided answering directly.

Because Iran uses this engine (and its derivatives) in its planes? Why does Iran have test stands for other engines? You are asking why Iran is building a facility that is key in the repair and maintenance of engines. These are things that Iran needs to be a regional maintenance hub for aircraft (which it has stated is it’s long term goal).

Iran has one of the oldest civilian fleets in the world. If it doesn’t learn to build critical parts for the engines then it’s air fleet will start to be grounded in the next 10 years more than it already has.

There is no Iranian CFM-56 coming anytime soon. Rest assured.

You guys do this all the time celebrating things without any proof of results. First with Qaher, then Kowsar, then Owj, then FJ engine, now this.

Either you all have memory of gold fishes or reality sets in 6-12 months (or longer) later and you realize your assumptions were beyond optimistic and bordering on delusional.

Don’t worry, I’ll be here to provide much needed skepticism.
