Meanwhile, ISRO has started forming concepts to develop a rocket that can put a 10-tonne satellite into orbit. This vehicle would require powerful engines. One candidate is the semi-cryogenic engine, using kerosene and liquid oxygen, whose design is now over. The hardware is being built and facilities being created. When ready, it will be an efficient lower stage with a thrust of 200 tonnes and controllable in flight, good enough to go into the lower stages of a large rocket. ISRO's plans are to use it in the heavy lifter and the reusable launch vehicle.

This LV should be similar to Atlas V ie 2 x 450klb 1st stage RP1 engines plus cryogenic upper stage.

Semi-cryogenic Engine: ISRO Charting a Revised Plan

Hit by delays, the Indian Space Research Organisation’s (ISRO) efforts to create a rocket engine which uses kerosene as propellant is getting a revised plan.

Quote
The new ISRO chairman A S Kiran Kumar has asked the Liquid Propulsion Systems Centre (LPSC) to prepare a brand new-schedule for the semi-cryogenic engine project as it is running behind schedule. As per the original plan, the semi-cryogenic engine should have been ready by 2014, but delays in setting up test facilities at the LPSC unit in Mahendragiri, Tamil Nadu, had dragged the project.

Kiran Kumar, who took over as chairman in January, reviewed the progress during a recent visit to the LPSC HQ in Valiyamala, Thiruvananthapuram, and recommended a revised plan.

The new schedule for the semi-cryo engine will be readied on the basis of the report prepared by the LPSC, LPSC director Dr K Sivan said. ‘’We are making all efforts to speed up the project. The ISRO chairman has recommended a revised plan and we are working on it,’’ Sivan said.

LVM3-SC rocket powered by the SCE-200 Semi-Cryo Engine

The SCE-200 is a liquid-fuel rocket engine being developed by the Liquid Propulsion Systems Centre, a subsidiary of ISRO. It is being developed to power the future heavy-lift Unified Launch Vehicle (ULV) and Reusable Launch Vehicle (RLV) being planned by ISRO but before that it will be tested with GSLV Mk III by replacing L110(powered by old Vikas engine) stage to SC160.

Here is how this version of GSLV-3 would look like. All specifications are based on available valid data.

The appear to increase the upper stage propellant by 20%, too. At 6.2tonnes it can launch, almost, anything commercial.

Nice find! Would be interesting to have the dimensions of the CLC.

more importantly, what the hell is this thing ?

The ISRO is working on its new-generation, Rs. 1,800-crore third rocket programme, called the semi-cryogenic launch vehicle, to beef up its current portfolio of the PSLV and the GSLV.

They are referring to HLV

The SCE200 is 2MN (460kbl) RP1 engine for the 1st stage. According to Wiki it will fly in GSLV MK3 initial then be used in a new LV.

NB 2 of these engines plus the new upper stage (CE20 200kN LH2 engine) they are developing and ISRO has a Atlas V class LV.

This is a rather needless and irresponsible media announcement by ISRO about Russian tie-up vis-à-vis Indian Semi Cryogenic Engine Development as if Russia will transfer technology to India. The cooperation would be just about the testing of the semi cryogenic engine at Russian Test Facilities until ISRO's own Semi Cryogenic Engine Testing Facilities come up later at Mahendra Giri, IPRC ( ISRO Propulsion Complex ).

ISRO shouldn't have made this announcement to avoid being arms-twisted by the USA, as it would not like ISRO to develop Semi Cryogenic Engine Technology that will pave the way for ATLAS V type HLV development in the long run by ISRO. I hope, ISRO does not get into any sort of Cryogenic Engine type trouble of 1990s because of the profuse publicizing of this type of news by the Indian Media that can't keep quite regarding any Hi-tech research that India Scientific Establishment embarks upon. Indian media is India's Scientific Establishment’s biggest enemy. If we search in any search engine with the keywords such as cryogenic engine, semi cryogenic engine, 90% of the websites that will appear in the top 20 to 30 positions will belong to India's cryogenic and semi cryogenic engine related news. While we can't get as much news of China's Semi Cryogenic Engine Development as possible.

By the way the author’s reporting that India will be the third country to achieve this Semi Cryogenic Engine Technology after the USA and the Russia is completely wrong. China has already developed 2 Semi-Cryogenic Engines.

1  )  YF-115 that has Thrust (vac.) of 176.5 KN / Thrust (SL) of 147.1 KN will be used in the Long March 6 second stage and Long March 7 second stage.

2 )  YF-100 Semi Cryogenic Engine that has Thrust (vac.) of 1,340 KN [ Thrust (SL) 1,200 KN ] will be used in the Long March 5 as K3-1 ( 2X YF-100) and K2-1 ( 1X YF-100 boosters ), Long March 6 first stage and Long March 7 first stage and boosters.

Though this is going quite off topic,but i agree with you.Their jingoistic nature is creating a lot of embarrassment to the government and the society at large.Even more than media i hold ISRO responsible for selectively leaking internal stuffs.I don't know what do they get out of this ?

As far as international reaction is concerned,we should be worrying more about Ukrainian reaction than US's reaction.

Testing an engine of Ukrainian design on Russian facilities,won't that create some political issues ?

If the history in below link is true , then India is at loss as "it could not be copied, modified, upgraded, re-exporter nor transferred to a third party without the permission of Yuzhnoye "

https://en.wikipedia.org/wiki/SCE-200


For any higher thrust engine, India again needs to start from scratch.

I wrote that based on WikiLeaks cables of the Kiev US Embassy. That story happened during 2007/8. As you can see, it took the Indians 7/8 years to get to a test stand. That's because they had to figure out why each part worked the way it worked. All they got was a blue print, with no engineering explanations behind it. In fact, now there's a CFD software that ISRO is willing to sell. And there are a long list of pictures of ISRO testing from a single injector element to parts of the powerhead. They can build as many SCE-200 as they want, and they have learned a lot. Please remember that they have already developed a staged combustion engine (the CE-7.5). Without the Ukrainian connection, going straight to a ORSC 200tnf engine would have been almost crazy. But getting something that should work (Yuzhmash didn't built one, only designed it), helps you a lot in reverse engineering it.

The information is that wikipedia article is outdated and misleading. As far as i am aware Ukraine supplied blueprints for certain components of the engine and provided input into the development of a certain alloy but ISRO still has the ability to upgrade and use the engine however they want. In fact there was some speculation sometime ago about the thurst being increased by 25% for application in a super HLV rocket however there are no official sources to back this up.

my guess is cold flow test is done as they are already talking about hot testing the engine in 6-8 months.
