برنامه‌های پژوهشگاه در زمینه ساخت ماهواره‌ها



رییس پژوهشگاه هوافضا با اشاره به اهداف سند هوافضا کشور یادآور شد: بر اساس این سند تا سال 1404 ایران باید ماهواره 500 کیلویی خود را در مدار ژئو (36 کیلومتری) قرار دهد.



امی با اشاره به آخرین ماهواره پرتاب شده کشور یادآور شد: ماهواره فجر که آخرین ماهواره پرتاب شده ایران است 50 کیلوگرم وزن داشته و برای رسیدن به وزن 500 کیلوگرم نیاز به نیروی رانش بالاتری خواهیم داشت.



وی همچنین با تاکید بر تمرکز فعالیتهای تحقیقاتی این پژوهشگاه در زمینه موتورهای فضایی خاطرنشان کرد: برای افزایش نیروی رانش باید به بخش موتورهای فضایی توجه شود و موتورهایی با پراکس بالا در کشور ساخته شود.

اُمّی افزود: با این حال، شهید مقدم گفت من این خطر را قبول می‌کنم و شروع به ساخت پروژه جدید کرد تا ماهواره بر با سوخت جامد بتواند ماهواره را در مدار 1000 کیلومتری قرار دهد.

وی خاطرنشان کرد: این پروژه «موشک قائم» بود که یک موشک «4 مرحله‌ای» تماما با سوخت جامد است. در سه مرحله تستها موفق بود و در مرحله آخر این اتفاق افتاد.


Conclusion : Qaem is not designed for Geo . Sure it's a big Slv but being big doesn't mean it can transfer a huge payload . For example check these two solid fueled ballistic missiles :

Sejjil

Weight 21,500 kg
Length 18.2 m
Diameter 1.25~1.50 m
Range : 2500 kilometers


MGM-134 Midgetman

Weight 13,600 kg
Length 14 m
Diameter 1.17 m
Range : 11,000 kilometers


I guess Qaem uses the same fuel as sejjil (If not then again not a much more powerful fuel ) . The fuel is not that powerful to make too much thrust so they need to make huge motors ( like the fist stage ) to increase thrust and its payload capacity .

1000 km orbit . It will be sth with the same capability as start 1 :

start 1 : based on topol icbm
Capacity
Payload toLEO
532 kg (1,393 lbm)
Payload to
SSO
167 kg (368 lbm)

But let me make it clear . It's still a huge progress if it be successful . We launched the first sat in 2009 . our current launcher can launch nothing but a 50 kg micro sat for couple of months . With this one we will be able to put operational 500 kg sats into 500 -1000 km orbit and use them for years not days or months . and who knows maybe a potential silo based Icbm .

You better to compare it with VEGA

In terms of size Qaem will be bigger than vega rocket (first stage of Qaem is 20 m ) . In terms of capacity maybe ~

Hi, dude, not heard of you in a long long time, miss you bro.
BTW, you've turned into a pro in these launching vehicles thing, very interesting
Hi bro . thanks .how is everything ?
I used to make R Candy (small rockets ) as a kid :D
Hey ! mix sugar + KNO3 ( 13:7 oxidizer to fuel ratio . Sugar is fuel ) heat it until it melt and put it in a soda can . Now you made a palestinian micro qassam rocket :lol:
 
everything fine bro.
So we literally have a rahi moghadam here. :lol:
Hmmm, sugar, so officially you were the first Iranian making a solid fuel missile. :big_boss:

NASA established theCommercial Orbital Transportation Services (COTS)program to develop a competitive market for crew and cargo flights to the International Space Station (ISS). The program breaks from the traditional government contracting approach by allowing the private sector to develop, own, and operate its own launch vehicles in service of NASA's ISS delivery needs. Unlike today's Space Shuttle, the reusable launch vehicles (RLV's) developed under COTS will also be able to serve commercial customers.
The original COTS announcement listed several capability requirements. These included the ability to lift a combined total of "up to" 16 tonnes of cargo per year to ISS using two to eight flights per year. Thus, the minimum launch vehicle/cargo carrier would need to be able to haul at least 2 tonnes of cargo per flight.

In August 2006, NASA announced its competitive selection ofSpace Exploration Technologies(SpaceX) andRocketplane-Kistler(RpK) as partners in the COTS program.

In November 2007,PlanetSpacecompany, announced that it had teamed with aerospace giantsLockheed Martin and ATKto submit a proposal response for NASA's COTS (Commercial Orbital Transportation Services) program. The proposal was triggered by NASA's October 18, 2007 decision to cancel Rocketplane-Kistler's original COTS contract.
Meanwhile, it can be contemplated alongside other proposed launch vehicles likeOrbital SciencesTaurus II andSpaceXFalcon 9.
The PlanetSpaceAthena-IIIrocket would stand somewhere in the 52 meter height range, including 10 meter long payload fairing, would weigh 439 tonnes at lift-off.
The first stage would be based on ATK's Space Shuttle Reusable Solid Rocket Motor (RSRM). It would use 2.5 motor segments.
The second stage would be an ATK Castor 120 motor.
The third stage would use a new ATK Castor 30 motor. Castor 30 should be loaded with 13,000 kg of propellant at launch. ATK has been developing Castor 30. Castor 30 appears to match the reported second stage requirements of Orbital Sciences Taurus-II COTS launch vehicle proposal.
The launch vehicle would be topped by an Orbit Adjust Module (OAM) of the type previously flown on Lockheed Martin's Athena-I and -II launch vehicles. OAM was a pressure-fed monomethylhydrazine (MMH) propulsion system that provided on-orbit maneuvering and trim.
The new launch vehicle would be able to lift about 6 metric tons (tonnes) to low earth orbit (LEO), using existing Shuttle SRB-style steel motor casings. New composite first stage motor casings would improve LEO performance to 6.71 tonnes. ATK said that the launch vehicle (presumably the composite case version) would be able to boost 2.79 tonnes to geosynchronous transfer orbit, 1.88 tonnes to a trans-lunar trajectory, and 1.36 tonnes toward Mars.
 
Loopholepalooza: Menendez Rips Holes in Iran Deal | PJ Tatler

“As I read the Security Council resolution on page 119, the ban on Iranian ballistic missiles has, in fact, been lifted. The new Security Council resolution is quite clear. Iran is not prohibited from carrying out ballistic missile work. The resolution merely says, quote, ‘Iran is called upon not to undertake such activity,’” he said. “Now previously, in Security Council Resolution 1929, the council used mandatory language where it said, quote, ‘It decides that Iran shall not undertake any activity related to ballistic missiles capable of delivering nuclear weapons.’”

“Why would we accept inferior language that changes the mandatory ‘shall’ to a permissive ‘call upon’? We often call upon a lot of countries to do or stop certain actions in the U.N., but it doesn’t have the force of shall not which has consequences if you do. Can you answer simply, is Iran banned from ballistic missile work for the next eight years?”

Chairman Bob Corker (R-Tenn.) dryly interjected, “No.”

“Do you want to answer it, senator?” Kerry snapped.

“Yes, I will,” Corker shot back.

Kerry argued that Menendez wasn’t reading the resolution correctly and it includes “the same language as is in the embargo now — we transferred it to this and that’s what it is.”

“Not the same language as Security Council resolution 1929,” Menendez replied. “I don’t know why you wouldn’t just keep the same language, which is that you ‘shall not.’”
