Safir-2 (Simorgh) IRILV

 
 

 

The empty casing of a Simorgh rocket, shown on the museum grounds of the Defense Ministry, is now real. On new photos, numerous details are visible. It is clear now that the Simorgh is significantly different to the  North Korean Unha-2/3. The data on the poster are compatible to the presented vehicle. The first stage is about 1.5 m longer and the tank volume ratio O/F is about 1.4  (Unha-2/3 is 1.6 !). For driving the first stage of the Simorgh will used a cluster of four Nodong engines, arranged like the unrealized Unha-1. The second stage is a longer Safir upper stage with expanded diameter. It will used four combustors of the LRE-4 (4D10V) with two turbopumps. The first stage have four added steering engines (not identical to the Unha-2/3) with own turbopump. But, in this configuration, only with a third  stage the necessary final velocity will be achieved. A third stage can be a solid fuel motor Saman-1.


      

The integration of a fifth turbopump for the steering engines requires larger gaps between the main engines (unlike the Unha-2/3). It is remarkable that the combustors in the Simorgh are rotated arranged for 45 degrees in comparison to the Unha-2/3.  Due to the increased consumption of fuel by the strong steering engines, the first stage is longer. It imposes itself on the suspicion that the Simorgh rocket in reality is an earlier unrealized version of the North Korean Unha-1 !

                                                                                                                                              
TEHRAN, 2017, July 27 --
Iranian semi-official media are reporting that Iran has successfully launched the Simorgh  rocket. The semi-official Fars news agency, reported the launch and said it was successful. The Imam Khomeini Space Centre was officially opened with the test of the Simorgh space launch vehicle", state television said.

  • Shahrabi (Iranian offical) said in an interview: "The launch yesterday, did not put a satellite in orbit".

  • "The project was successful, and we reached our intended goals" Defense Minister Hossein Dehghan said.

  • Iranian President Hassan Rouhani has appriciated the successful test-launch of his country’s new satellite carrier.

Note: The Simorgh is approximately 1.0 m longer in compared to the launch vehicle of 2016. An unit for a third stage (Saman-1 ?) was added. But the Simorgh supposedly failed.

                                                                                                                                                                                              

The endless story (press statemets)

2016, April 21 -- The launch of the Simorgh space launch vehicle two days ago was judged by U.S. intelligence agencies to be (partly) successful but did not reach orbit, said defense officials familiar with reports of the test.
Russian Ministry of Defence has told that suborbital launch of unknown ballistic missile has been occured at 09:33 UTC on April 19th and, according to preliminary data, was successfull. The burned out rocket impacted in the southern part of Iran.Two radars, in Armavir and in Orsk (Russia), have the launch registered.
Comment: Only a test of the Simorgh first stage ?. Probably not (
according new images of this launcher on the pad). Even though it was announced so in 2015 (Aug.). Iran will not comment this launch because is suspected wrongly that the Simorgh is an ICBM. What nonsense is.

TEHRAN, 2016, April 19 -- Today arrived President Rohani in Semnan city !?

TEHRAN, 2016, March 15 -- Head of Iran’s National Space Center Manouchehr Manteqi announced that the country will launch the indigenous “Simorgh” satellite carrier for test in early spring. Manteqi told the Tasnim News Agency that the missile will be launched in three phases: two test launches, one of which will take place in the coming weeks and the other in late summer, and a third launch, which will most probably take place in early 2017.
According to Iran’s Space Agency officials, the first generation of the satellite carrier is capable of carrying communications and sensing satellites as heavy as 100 kg to orbits some 500 km above the earth.

2016, Feb. 18 -- US-Intelligence agencies watching preparations to test a Simorgh space launch vehicle in this month. A large liquid-fueled rocket was observed on the IKSLC launch pad.

TEHRAN, 2015, Aug. 23 -- Iranian Defence Minister: The space program was slowed because of the budget limits. The only slowing factor has been budget and nothing else. We will start testing different stages of Simorgh this year and it will be able to put 200 kg in higher orbits. ( Note: Only able with an upper stage !). The 1st stage of Simorgh will tested this year. The 2nd stage was previously tested.

TEHRAN, 2014, May 29
-- Iran plans to launch three home-made monitoring satellites into orbit in the next Iranian calendar year (March 2015-March 2016), a senior Iranian aerospace official announced.
"Zafar, Tolou and AUTSat will be sent into space onboard the Simorgh satellite carrier," Deputy Head of Iran Space Agency (ISA) Hamid Fazeli said.
Zafar will be sent into a geostationary orbit (this is nonsense !).
