Rapid growth of private Aerospace sector in Iran; the second aerospace exhibition was kicked off in Tehran on Wednesday. More than 120 companies and organizations participated in the event. The main aims of the exhibition are to develop general aviation, display the latest capabilities of Iran in aviation industry, specially the private sector, facilitate communication among aerospace companies and to sign contracts and do more business.

Iran has been very active in the field of aerospace technology. It has launched three satellites named Sina-1. Omid and Rasad. Rasad was launched in to space on June of this year. In addition Iran has successfully manufactured two fighter jets named Saeghe and Azarakhsh. Government has been the major player in aerospace industry yet the private sector has also been very active in this field especially after the Iranian Aerospace Industries Association was found to support Iran's private Aerospace industry in 2007

Since the early years after the Revolution and because of the sanctions imposed by the West, Iran has been pushing to reach self-sufficiency in the field of aerospace technology

Thanks Catsoo.

Anybody knows what is this rocket engine?

Hopefully a.solution can be found for our national air carriers
A step backwards having to give our national air travel to Qatar

Some more images (click on them to see better)

These are images of booth of Turbine Engine Manufacturing Industries, they had shown some of their products like compressor blades, fuel control system and ...:

And these are images of Isfahan Alloy Steel Complex booth, as you see they produce some parts of V94.2 gas turbine generator and super alloys for aviation industry:

Great pics bro. Thanks.

btw I saw 2024-T3 aluminum between the produced alloys. These are used in supersonic aircraft. More steps closer to aircraft production.

"Hava NafarBar Duct Fan" has never been shown in the news. It is the first time such machine is publisized in Iran.

Also, back to the application of Farsi language currently in Iran, which I find endlessly interesting and probably boring to everyone else, on one of the banners I see the term 'ghata'ate bohrani' used, I assume, meaning 'critical parts'.  'bohrani' is from 'bohran' meaning 'crisis' which is different from 'critical' but obviously related. Again, I wonder if this is a misapplication/mistranslation or an intentional trans-literation (which works albeit a little awkwardly).  Regardless, the language has changed significantly in the past 30 years and, it seems, there are many many more Persian words being used, I assume, due to indigenous technological progress.

In the category of 'better late than never', the photograph shows an Isayev designed S2.720 engine originally used in the Soviet S-75M Volchov/Volga (i.e. SA-2) surface to air missile.  It produces about 3.4 tons of thrust, has a specific impulse of 233 seconds at sea level, and a chamber pressure of 5.7MPa.  It uses TG-02 fuel and AK-27 (IRFNA) oxidizer.  Wonderful piece of machinery considering it is 50+ years old.   Iraq used this engine to support production of the al Samoud missile in the late-1990s, early 2000s (pre-invasion).

Thanks for information, Its good to we have you here in this forum.
It has always been a question to me that if second stage of Safir is based R-27, so why thrust of its very low and isn't comparable to thrust of R-27(3.4 tons vs around 230 tons).
Now its interesting to see this small engine of SA-2 produces 3.4 tons of thrust too. You think why the thrust of second stage of Safir is so low, Can the 3.4 tons thrust that has been announced for thrust of second stage of Safir be misinformation?

M-ATF,
Thank you for the kind words.  This forum is one of the most informative and authentic to be found; all of its participants deserve credit.  With regard to your question, I offer two points of possible interest.  First, the Safir second stage appears to utilize the steering engines (thrust ~3.5tons)  found on the Soviet R-27 missile, not the main engine (thrust ~23 tons).  Note that the two steering engines, which are fed by a single pump, together generate about 3.5 tons.  And seconed, while this thrust level is approximately the same as that produced by the SA-2 engine, the specific impulse (energy generated per unit mass of propellant burned) for the former is about 22% more than the latter.  Thus the velocity change imparted to the satellite when using the R-27 steering engines is roughly 17-19% more than for the same second stage powered by the SA-2 engine.   I ignore some minor factors, such as propellant density, burn time, etc; this is why the numbers listed (22% vs. 17-19%) are slightly different.  In other words, if the second stage size remained the same, but an SA-2 engine were used in the Safir, the Omid and other satellites would not have achieved orbital velocities.

Finally, the SA-2 engine, as noted in my previous post uses TG-02 and AK-27 for its fuel and oxidizer; the R-27 steering engines employ UDMH and N2O2, which is more energetic.  Hope this helps.....
