    Iran's First Altitude Rocket Propulsion Test Facility



    Iran Tests First Sample of Home-Made Space Engine

    Tue Dec 17, 2019 3:38

    TEHRAN (FNA)- President of Iran's Space Research Center Hossein Samimi announced that the first sample of indigenized space engine was tested successfully.

    "The new achievement of the Center includes the designing of the class of Arash space engines and the first sample of this space engine was tested successfully last month," Samimi told reporters in a press conference in Tehran on Tuesday.

    He added that the engine should have been tested in vacuum, adding that the Iranian experts simulated a vacuum-like space for the test.

    "The first sample of this engine has been tested and another test is due to take place soon," Samimi said.

    Altitude Rocket Propulsion Test Facilities also called Vacuum Test Stands allow sea level static test of an upper stage.

    As we know that for the upper stages of the rocket, we need high propulsion efficiency thereby high specific impulse. For that we employ a nozzle with higher expansion ratios.

    Now, if we conduct the static tests of such nozzles at sea-level, it will result into an over-expanded plume.


    One needs a massive facility that can maintain a near vacuum while dealing with the engine exhaust. There are (were) only a couple in the U.S.:


    Plum Brook Station (Part of NASA Glenn) includes the In-Space Propulsion Facility

    1. U.S.' high altitude rocket propulsion test facility

    Arnold Engineering Development Center (run by the DOD) includes the J-6 Large Rocket Motor Test Facility
    • The never-used A-3 altitude test stand at Stennis, completed to the tune of over $350 million,

    These facilities typically use steam ejector systems to keep the test cell pumped down in the presence of huge amounts of exhaust entering it.

    Note: these facilities typically don't claim to produce pure vacuum conditions. Commonly they advertise 100,000 ft (~30 km) altitude conditions (~ 0.2 psi or ~ 0.0014 MPa)

    This means that although the Arash upper stage is not new, Iran has just made another major breakthrough, with its own indigenous Vacuum Test Stand, a milestone mastered only by a few space powers!

    By unlocking ground testing of upper stage techologies, Iran will soon be able to send its first ever satellite in a geostationary orbit!

    Say what you like about this guy. But he definitely knows how to handle PR.

    Hopefully they've ironed out the kinks with this rocket.

    really really big big news for Iran missile power with the new Arash space engines which until last year (2019) only was built by US alone but now Iran ( by successfully testing its first Arash engine in 2019 ) is the second power to build that kind of engines.



    Iran achieves knowledge of building space engines: ISRC head



    [​IMG]


    He said the new achievement includes the design and development of various versions of “Arash space engine” the first sample of which was tested successfully late 2019.


    “Arash space engine will be put in the orbital transfer system to help thrust satellites from the low orbit into the high orbit.”

    Is it a small engine or a big SLV engine?

    Isnt it to big for a Sat? If the thinest cables in that pic are only 1 cm thick, then the complete Engine is bigger than 3 meter.

    Edit:

    Hmm, but sure larger than 2 meters!

    They talk about vacuum optimized small upper stage engines. In best case cryogenic, but given Iran's low publicised skills in developing indigenous liquid engines, that's rather unlikely.
    However a vacuum testing stand on it's own is already a impressive job.

    Zafar 1, 2 satellites ready for launch

    19 January 2020 - 10:34

    TEHRAN, Jan. 19 (MNA) – Iran's Information and Communications Technology Minister Mohammad Javad Azari Jahromi says the Zafar 1 and 2 satellites, have been delivered to Iran Space Agency and will be put into orbit in the near future.

    He described the developments of these satellites and their launchers as a great step in the country’s space program, saying, “Two versions of Zafar have been built by young Iranian scientists, both of which are technologically superior to those we had built before.”

    Zafar, designed by Iran University of Science and Technology, is a 90-kilogram remote-sensing satellite equipped with color cameras and can be used for surveying oil reserves, mines, jungles and natural disasters. If the launch is successful, it will orbit the earth at an altitude of 530 kilometers.

    Satellite Zafar, built by Iranian universities' elites and scientists, will be delivered to the spaceport today and the process to launch it into the orbit will start immediately, Barari told FNA on Sunday.

    From the Mission Control screen, seemingly a polar orbit. 530 km circular SSO is consistent with any remote-sensing satellite.
