Hi there!
China is developing their 120 tonnes thrust semi-cryogenic engine and it is not ready yet.As for ISRO,they are working on a 200 tonnes thrust SCE that will replace vikas engine as the main central core in GSLV MK-3.So it is certainly not correct to say that chinese are ahead of us in SCE technology,having said that,chinese are definitely ahead in the manned space program with "human rated launchers"-which is no small feat!
Once developed, ISROs semi-cryogenic engine will be bigger than the chinese SCE which they are developing at the moment!

I would also like to point out that the mainstay of chinese upper stage booster happens to be a cryo engine with nominal vac thrust of close to our own CE that was put on GSLV D5 flight(close to 75kN)- however chinese engine is different in the sense that it uses a clustered configuration with two thrusters providing a total thrust of close to 150kN! Their engine also has re-starting capability which translates into precise planetary insertions.However their engine seems to be based on gas generator cycle as opposed to india's staged combustion cycle.
With CE-20, india will have upper hand in cryogenic engine(also note that CE-20 will feature re-ignition capability) but that is not to say chinese are sitting idle,they are working on their 600kN cryo engine(although that is still some time away for functional deployment).
India's 600kN cryo is unfortunately still on drawing boards

ISRO Plans to Test-fly Reusable Launch Vehicle by Mid-2015

Taking India’s ‘space shuttle’ dreams a notch closer to reality, the Indian Space Research Organisation (ISRO) plans to test-fly the Re-usable Launch Vehicle-Technology Demonstrator (RLV-TD) by the middle of 2015.

“The test-flight will take place either by the end of the first half of this year or the beginning of the second half. Work is progressing satisfactorily,” ISRO’s new chief A S Kiran Kumar told Express on the sidelines of the three-day International Conference on Climate Change and Disaster Management which began here on Thursday.

“This first test is one of a segment. Work on the RLV is progressing in steps,” he said.The unmanned, sub-orbital mission will lift off from the second launch pad of the Satish Dhawan Space Centre (SDSC), Sriharikota. In simple terms, the two-stage technology demonstrator is a ‘space plane’ rigged atop a rocket. “The first stage burns on solid fuel. Atop it is the space plane which will return to earth after the flight,” Kiran Kumar said.

At present, for placing satellites in orbit, ISRO uses the Polar Satellite Launch Vehicle (PSLV) and the Geosynchronous Satellite Launch Vehicle (GSLV), both expendable vehicles. A Re-usable Launch Vehicle (RLV) – think NASA’s space shuttles – will bring down expenses phenomenally and is the next big leap in ISRO’s launch vehicle programme.

Kiran Kumar, who took over as ISRO chairman in January this year, also listed his other priorities for the space agency. Increasing the number of missions, completing India’s navigational satellite constellation and the big cryogenic engine for the Mk-III version of GSLV are a few.

“We have to streamline the whole process. We are actually behind schedule in many programmes,” he said. An important project underway is the development of the semi-cryogenic engine, which, again slashes launch costs remarkably. Whereas a cryogenic engine uses Liquid Hydrogen (LH2) and Liquid Oxygen (LOX) as propellants, a semi-cryogenic system replaces LH2 with cheaper and easier-to-handle kerosene.

Well I spoke to a ISRO employee during Aero India. He told me this will only be a tech demonstrator and for a operational model it is going to take sometime.

Any update on this?

Any update on this?

Shifted to mid 2015, between April-June this year.

A total of four RLV-TD flights are planned by ISRO.

• HEX (Hypersonic Flight Experiment)
• LEX (Landing Experiment)
• REX (Return Flight Experiment)
• SPEX (Scramjet Propulsion Experiment)

Any idea about the timeline for the 4 tests?

How do we know if there won't be more delays, I mean shift in the future. India like to shift projects more often than anyone else.

Oh yea like F35 again an Indian project Though you love to wear US flags but that doesnt stop your obsession.

Actually with respects to the development of the technology itself, the CNSA have demonstrated their capability of building them, namely, with their YF-77, YF-75/D, YF-73, and YF-50T series, the latter being the future engine for the smaller stages of the Long March 5 rocket.

Please stop replying to that loser, he is a fake Ameican. Created this user to only trolling in Indian threads.

People have so much time lo.

The time frame for all of the four launch experiments is 2015-2025. After all of these four technologies when integrated into one will form what will be the Indian counterpart of the American Space Shuttle.

Kindly refrain from replying a false flag troll - no one gives a fcuk to what that moron says - he has no self respect.
