In a recent interview LPSC director casually mentioned they have began manufacturing the first test engine
Considering that the global space market’s future will be defined by heavy lift boosters, it is imperative for Isro to develop the GSLV’s advanced avatars as soon as possible. The international launch scene is changing rapidly with newer launchers constantly pushing the bar higher on payload capability.Isro scientists seem ready for the challenge and have set their sights on leapfrogging to GSLVs powered by semi-cryogenic engines. Fuelled by kerosene and liquid oxygen, these engines would be capable of lofting ten-ton satellites into space, cutting launch costs dramatically. "We expect to test the prototype of a semi-cryogenic engine in a year’s time," says Somnath. "And we may fly it by 2021. Engine development takes a very long time, at least 10 years for realisation."
"Various tests are in progress on the engine. Of the four turbo pumps in it, three have undergone tests at the ISRO Propulsion Complex, Mahendragiri. We plan to have the engine ready by 2019 end, the stage by 2020-end and the first flight by 2021,’’ S Somanath, director, LPSC, said. LPSC had developed the cryogenic engine for the GSLV Mk-II and the much powerful one for the GSLV Mk-III. The idea is to replace the second stage of the GSLV Mk-III, which now uses a liquid stage, with the semi-cryo. The rocket will retain the cryogenic upper, third stage.The advantage of inducting the semi-cryogenic stage is the payload capacity of the GSLV Mk-III will increase from four tonnes to six tonnes. Using refined kerosene as fuel has quite a few advantages: It is eco-friendly and cost-effective.
is sce-200 being built by isro based on re-usability in mind or not and recently “somanth lpsc director said sce-200 stage will be ready by 2021”But why that much time why cont we replace GSLV Mark-III L110 liquid stage with sce-200 stage within 1 year after materializing sce-200 engine is it testing will take like 4 years from now…but chines did it in after 2 years from initial prototype…

Each engine can be reused up to 15 times. I know the semi-cryo engine intended for use in the planned TSTO (Two-Stage-To-Orbit) vehicle is supposed to be reusable as you've said, however it's not clear to me whether that engine is the same as the SCE-200, which is meant for replacing the GSLV-Mk3's L110 stage (UDMH/N2O4).Logically, it might be practical for ISRO to first get SCE-200 non-reusably flying on GSLV-Mk3, which is an expendable launch vehicle, even while it works to achieve reusability on its semi-cryo engine meant for TSTO.
The testing facilities at the ISRO Propulsion Complex, Mahendragiri, are being augmented for the engine being developed by the Liquid Propulsion Systems Centre here under a project codenamed SCE 200. Three of the four turbo pumps of the new engine have been tested and the pre-burner and thrust chamber are being readied for testing, LPSC Director S. Somanath told The Hindu.
ISRO scientists have simultaneously begun work on the stage configuration. ‘‘We hope to complete the development of the engine by 2019. The stage test is expected to take place by 2020, followed by the first flight test in 2021,’’ he said.
A clustered semi cryogenic booster with a more powerful cryogenic upper stage is another possibility. ‘‘Once we have mastered the technology, we could possibly go on to modular development of rockets with different configurations,’’ Mr. Somanath said.
But before that, ISRO needs to ensure that critical technologies such as special materials and coatings, brazing process, kerosene refinement, combustion instability and control components are mastered and the necessary infrastructure is in place.
Does any know what the name of GSLV Mk.III with the SCE200? Is it GSLV Mk.IV?
According to ISRO fully integrated SCE-200 will be delivered ready for testing by the end of year. A hot fire should take place between Jan-June 2018 depending on readiness of new testing facility.

Ukraine to test components of a powerful Indian rocket engineThe Yuzhmash production plant in Ukraine prepares to begin a series of firings testing critical parts of a large rocket engine intended for India's next-generation heavy launcher. Although it was built entirely in India, the prospective engine was originally designed in Ukraine under designation RD-810.....Foreign roles for RD-810Over the years, various roles were proposed for RD-810, including replacing the Russian RD-171 on the Ukrainian-built Zenit rocket and propelling Ukraine's new-generation Mayak launcher. A four-engine cluster, dubbed RD-810M, was designed to fit into the aft section of a potential space booster with a diameter 3.9 meters, matching the caliber of the Zenit rocket. Each RD-810 was expected to gimbal up to six degrees around one axis, allowing the four-engine cluster to fully steer the rocket.Because none of the indigenous programs could be adequately funded, Ukraine sought to bring the RD-810 design to the international market. Along with several other Ukrainian designs, the RD-810 was proposed for the American super-heavy rocket developed under the Space Launch System, SLS, program. However, despite qualifying RD-810 as in high degree of readiness, American space officials did not seriously consider Ukrainian engines for the SLS project.Indian versionIn 2005, Ukraine agreed to provide India with designs for the RD-810 engine and, on Nov. 20, 2006, the Indian Space Research Organization, ISRO, awarded a contract to KB Yuzhnoe for a project code-named Jasmine, which officially started the development of the RD-810. In India, the RD-810-based engine was dubbed SC-200, which stood for "semi-cryogenic," indicating the use of kerosene fuel, which can be stored at regular temperatures, and liquid oxygen, which requires cryogenic conditions to stay in liquid form. The "200" in the designation denoted its thrust of 200 tons.ISRO planned to install the SC-200 engine on the modified core stage of the GSLV Mark 3 rocket replacing the older propulsion system. It would boost the payload capacity of the rocket to the geostationary transfer orbit from four to six tons. Later, four similar engines could propel a new-generation rocket, which could deliver up to 10 tons to the same orbit without the help of strap-on boosters.In addition to assisting with the design of the engine, KB Yuzhnoe also advised ISRO on the development of the prospective launch vehicle itself.As of 2014, KB Yuzhnoe had produced the full set of design documentation required for the production and testing of the engine. (809) According to industry sources, India then re-issued the blueprints for the engine according to its own standards and, possibly, introduced some modifications.In the meantime, KB Yuzhnoe decided to stop further development of the RD-810 engine inside Ukraine, focusing instead its limited resources on the more powerful RD-815 design, which could potentially be promising on the US market.Testing RD-810In 2017, Indian specialists returned to Ukraine to test fire the actual hardware, which had been built in India within the Jasmine project. According to industry sources, the Ukrainian Yuzhmash factory was contracted to test, not the entire engine, but its critical components, including its gas generator and a turbopump, which had all been manufactured in India. If the firings, apparently planned to be completed by 2019, validated the quality of the Indian manufacturing methods, the fully assembled engine, including the combustion chamber and the nozzle, would be tested at the yet-to-be completed bench facility at Mahendragiri, India....
