SCE-200 Semi-cryogenic Engine - News, Updates and Reports

[Zebra]

From @Indx TechStyle
This edit is being made on 11th of July 2022 to put summary on lead.
SCE-200:

• A Kerolox Semi-cryo engine based on Staged Combustion Cycle. It will be the base of India's upcoming heavy cargo rockets and engines.
• Has a vacuum thrust of 2,030 kN (1800+ kN at sea level) as core engine alone.
• Based on Soviet RD-120 design (which was used in USSR's first super heavy rocket energia) and shall be among largest operational engines in world (unless shit happens).
• Shall boost LVM3 rockets capacity to 5.5 to 6 tonnes against existing 4 tonnes to GTO.
• It's clustered group and further derivatives will power India's upcoming UMLV rocket family and HLV (Indian equivalents of Delta-IV Heavy, CZ-5, Ariane-5 and Proton-M) and later on ISRO's SHLV (Falcon 9 Heavy, Vulcan, Saturn-V, SLS and Long March 9 etc. class rockets).
• Envisaged in 2000s, India tried to get blueprints and technological knowhow of the post-Soviet tech from Ukraine's Yuzhmash office. The program since then has moved slowly but had been nearing culmination until Russo-Ukraine war delayed it. It shall be progressed and tested in India only further.
• It's realisation will zero the gap of launch payload of India with other major space powers, hence enabling country to launch heavy satellites and cargo for space stations etc.. Though issue of launch frequency due to few spaceporrs and rocket production rate shall remain low for a while.

Godrej Aerospace to make semi-cryogenic engines | Business Line

Chennai, December 18:

Godrej Aerospace, a division of Godrej & Boyce Ltd, has been mandated by the Indian Space Research Organisation (ISRO) to produce the more powerful and environment-friendly semi-cryogenic engines for it, the company's Executive Vice-President and Business Head, SM Vaidya told BusinessLine.

Godrej has been supplying the Vikas engines for ISRO's rockets, including two for the GSLV Mk III that flew today. Vaidya said the company has supplied over a hundred Vikas engines (which are, incidentally, named after Vikram Ambalal Sarabhai, India's renowned space scientist.)
Long delay

While cryogenic engines use liquid oxygen and liquid hydrogen, semi cryogenic engines (SME) use a combination of liquid oxygen and kerosene.

These engines have been used in American and Russian rockets for long. They powered the Saturn V rockets that took Americans to the moon; the Russian RD-180 engines have been used in Boeing's Atlas V rockets.

The SME project was approved by the Government of India in January 2009 at a sanctioned cost of ₹1,798 crore. Department of Space's Outcome Budget for 2014-15 says that the project is "in the initial stages".

It expects the engine to be fully developed "after six years".

Till the end of March 2013, ISRO had spent ₹155 crore on the project. Godrej will make six engines for ISRO. Vaidya said the company had begun work on three.

The SME is meant to power the future GSLV Mk III rockets as well as the heavy-life Unified Launch Vehicles, or ULV, which is today only a concept. The ULV will be a modular vehicle where the number of engines used will be based on the weight of the satellite or spacecraft.

The rocket will feature a combination of SME and an Indian cryogenic engine.

My mind be like sce-200 toh gayoo.

ISRO already developing gslv mk3 with own. So no issue.

Nothing will impact ISRO development.

Sce-200 is extended version on gslv mk3 having completely different engine

They will... after all they are the ones who gave us KVD-1, Nuclear subs etc ...also Ukraine is only part of initial testing of the engines...that's it....we got complete "know-how" many years ago...also isro gained "Know-why" entirely on its own using its own R&D.

GalacticNemesis
Being closely involved in the Semicryo Project I can tell that along with minor subassembly tests, two major tests are planned in Yuzhmash Ukraine: 1)Power Head Test Article (PHTA) & 2) Integrated Engine Test 1 (IE-1). Following these tests, IE-2, IE-3 & IE-4 tests are planned in IPRC. Engines used in IE-3 will be used for stage hot test and IE-4 engine will be used in flight stage.

As the current progress stands to the best of my knowledge, integration in the subassembly level is being carried out. Subassembly level tests (cold) are being done in IPRC. But due to a crucial component failure, a particular subassembly is not getting qualified. Subsequent to the qualification from IPRC, the engine will be sent to Yuzhmash for testing.

With respect to the test facility, it will take another 6-8 months for completion of SIET facility.

Realistically speaking, even if the engine was delivered to Ukraine today, it will take a year to carry out the tests there. We would have first SE-2000 engine testing in IPRC next year. The subsequent engine and final stage tests would be another 1-2 years. And maybe after that the first developmental flight. So optimistically we should see the first developmental flight by 2025-26 if nothing else delays it.

I am working in the production facility where SCE-200 is being manufactured, i can't give much info but a total of 14 engines are being manufactured. Two independent private companies in india (7 each) are given contract. Currently two thrust chambers are rough machined, will take atleast two year for 1st engine to get manufactured and assembled . But LPSC might have already manufactured one before giving contract idk.
We are getting most of the raw material from Ukarine.

What will happen with SCE-200 engine? Initial tests were scheduled to be conducted in Ukraine.

This panic about SCE-200 is unwarranted...as I said earlier we got complete "know-how" of the engine....the only thing in which Ukraine is involved with SCE-200 is, it's initial testing....our test stand should be ready this year....Yes, it will be delayed ,but not indefinitely

No one said it is indefinitely delayed ukrain is not the only testing site it depends how fast we can choose alternative testing facility and go with it given that our record of red tape it's not that good we don't have facility for those initial testing for rest of the engines we have facility that is the issue.

Although I always doubted Ukraine intention

Maybe relieving news for SCE-200.

Yuzhmash rocket factory remains intact and its destruction was the fake news.

Still the engine might get delayed owing to conditions of war and Ukraine being upset with India on political stance.

 

[Swesh]

SCE-200 might be getting tested in about three months


crux is according to ISRO Chairman S Somanath Semi-cryogenic SCE-200 engine is getting ready to be tested within India in three months. It should mean test facility for it should be more or less ready

पूरी तरह स्वदेशी तकनीक पर हो रहा है काम : डा. सोमनाथ ने बताया कि इसरो अब पूरी तरह से स्वदेशी तकनीक पर काम कर रहा है। तीन महीने बाद देश के पहले सेमी क्रायोजेनिक इंजन का परीक्षण किया जाएगा। यह 200 टन ईंधन क्षमता का होगा। इसकी सफलता के बाद जीएसएलवी मार्क-3 की पेलोड कैबेलिटी को चार टन से बढ़ाकर 5.5 टन कर दिया जाएगा। यह सेमी क्रायोजेनिक इंजन में केरोसिन और हाइड्रोजन तथा आक्सीजन आक्सीडाइजर पर आधारित होगा। वार्ता के दौरान आइआइटी के निदेशक प्रो. पीके जैन, बीओजी चेयरमैन पद्मश्री डा. कोटा हरिनरायन भी उपस्थित थे।
