50 kg is the weight it usually failed , it could not reach 400km previously , this time it reached a 450km x 1100km orbit

It failed because it had a insufficient 2nd stage: that was the design flaw.

This time it was still less than 50kg or maybe around that area. 32KG + 10KG in nano satellites. Let’s not forget the claimed payload capacity for Simorgh was up to 200kg.

To fix the underpowered design flaw they added R-27 in second stage. Picture is there for all to see. However the diameter was too small so they couldn’t put the two thrusts side by side and had to improvise.

If R-27 was enough of a solution they would have stuck to 75-100kg weight . The fact they dropped so low makes you question the long term solution as a launcher.

Nothing to do with weight of casings.

They can order Khorramshahr engines from MOD without issues, it's clearly in mass production in more than one variant already

They already used R-27 in this Simorgh variant. That is why it was able to get enough speed.

Can this new version lift 100-150kg? Skeptical. Seems like a stop gap measure until Sarir is ready. Not sure status of Zoljaneh after a few attempts

Sarir is supposed to be built on Simorgh first stage so this is pretty concerning

I hope they find new first stage for Sarir, no excuse to still use clustered Scud engines in 2024

Zoljanah has a pretty powerful engine (which came out of nowhere) and is basically equivalent to what Qaem-105 will be (less advanced but similar overall thrust / payload capacity). they mentioned 3-4 test launches and so far we had 2, a third one is overdue

personally I think they made Safir-Simorgh-Sarir plans from the start (2007-2010 era)

"TEHRAN, 2012, March, 02 -- Head of the Aerospace Industries Organization said there are plans to build the Safir-3 satellite carrier, capable of putting satellites weighing up to 500 kg into 1,000 km orbit."

500kg to 1000km orbit matches perfectly with Sarir claimed performance

Safir-1
Safir-2 = Simorgh
Safir-3 = Sarir
[Safir-4 = Soroush?]

the original ISA plan is outdated, they need to breathe fresh air into the program and start with new engines until Bahman cryogenic engine is ready. very easy to order Khorramshahr engines or cluster Zoljanah engines, both of these would be a huge improvement to Simorgh-Sarir

Yes, but big differences after that.



It appears Sarir will have elongated fuel tanks compared to Simorgh.

I agree that it’s a shame after 20 years, ISA is using clustered Shahab-3 engines for first stage. But I believe Zoljaneh has a different 1st stage. So will Soroush and future Iranian launcher using “Bahman” cryogenic engine.

There are quite of different programs in development, the issue is the speed is very slow even considering that space is a slow progressing frontier. Iran is lagging in advancement given the amount of time spent (at least since 2005) and what we have to show for it.

Funding and politics are playing a big part among other things.

good point about GEO orbits

 

[Immortals]

Soroush to be able to lift 6 to 15 tons into orbit. A beast in the heavy lift category.

The question is when it will be ready.

Earlier they said Souroush-1 will be ready by 2029 and Souroush-2 by 2032.

Since both have the same name, probably both of them will have cryogenic engine (Bahman engine).

 

[muhammed45]

According to defense ministry spokesman in space related issues, Soroush SLV will be able to carry a load of 15 tonnes to space.

Compared to the Saturn-V which is capable of carrying 50 tonnes of space load.

Soroush SLV




Saturn-V (almost 100 meter long)


Problem is, we won't be able to achieve the level of Saturn V in the next 20 years.

So we are at least 30 years behind USA in terms of space rockets.

We need to hurry, no time to waste. In the process, we have to keep losers like Rouhani in their rat holes to avoid any waste of time.

Sarir
Sarir-Heavy (3 liquid fuel boosters)
Soroush-1
Soroush-2 (Bahman cryogenic engine)

long way to go until we see Soroush, I will be happy if we see a successful launch of Sarir by 2026

SLVs in Soroush-1/2 class seems too expensive with current tiny budget. will not get my hopes up. best hope for success this century remains the IRGC space program

I hope we don't go after Saturn V design instead work on something like Falon-9 and Falcon Heavy

that program will never reach the size of Soroush as its solid fuel
about soroush the cost itself is not important , what is important is cost/(kg of payload)

It was just a comparison between their payload. Otherwise there are much better designs and configurations such as Atlas or Chinese long March 9.

Saturn V is outdated, imagine we are light years behind that outdated platform. The lost 8 years, almost a decade was lost. The huge gap will be closed in the next 30 years. Imagine we could wait for 20 years instead of 30 years. At least 30 years

on plus , waiting may be is not that long , it can be just the time to develop a cryogenic engine

Although I've been critical over the speed and rate of development of the Iranian space program over the past year, the recent developments bring hope. We've had three significant SUCCESSFUL launches over the past couple of months with a nice diversity of systems. Granted not enough data points, but if this rate continues the results will be significantly faster.

I'm eyeing Iran's roadmap to elimination of disposable systems, manned orbits, and planetary exploration. THAT is the big project and the real frontier. Heavy lift, IMO, is simply a requirement and not a real goal.
