The '''SE-2000''' (formerly known as '''SCE-200''', also referred as '''Semi-Cryogenic Engine-2000''') is a 2 [[Newton (unit)|MN]] thrust class liquid rocket engine, being developed to power [[ISRO]]'s existing [[LVM3]] and upcoming [[Heavy-lift launch vehicle|heavy]] and [[Super heavy-lift launch vehicle|super heavy-lift launch vehicles]]. It is being developed by the [[Liquid Propulsion Systems Centre]] (LPSC) of ISRO, and is expected to have first flight in 2020s.

The engine in September 2019 reportedly had become ready to begin testing in Ukraine and enter service no earlier than 2022. The use of engine of [[Gaganyaan|India's first human spaceflight]], hence was ruled out by ISRO. By November 2022, SE-2000 had neared completion of its qualification tests. The Semi-Cryogenic Engine and Stage Test Facility at the [[ISRO Propulsion Complex]] Mahendergiri was preparing for ground tests now that the SE-2000 had reached the final stages of development.<ref>{{Cite news |last=Rajwi |first=Tiki |date=2024-02-26 |title=ISRO's Semi-Cryogenic Engine and Stage Test Facility at Mahendragiri |url=https://www.thehindu.com/news/national/kerala/semi-cryogenic-integrated-engine-and-stage-test-facility-at-mahendragiri-to-boost-isros-efforts-to-develop-semi-cryogenic-engines-in-india/article67887701.ece |access-date=2024-08-18 |work=The Hindu |language=en-IN |issn=0971-751X}}</ref>

== Background ==
On 2 June 2005, India and Ukraine signed the ''Framework Agreement between the Government of Ukraine and the Government of the Republic of India on Cooperation in the Peaceful Uses of Outer Space'', which would enter in force on 15 February 2006.<ref name=mfa-ukraineindialegalacts /> Agreement also involved the transfer of blueprints for a rocket engine by the [[Yuzhnoye Design Office]]. The engine blueprints supposedly transferred by Ukraine to India, have been identified as the [[RD-810]] which in turn is a variant of Russian [[RD-120]].<ref name="RSW_RD810" /><ref name=godrej-presentation>{{cite web |url=http://www.godrej.com/godrej/PrecisionSystems/Pdf/semi_cryogenic_engines.pdf |title=Semi-Cryogenic Engines |url-status=dead |archive-url=https://web.archive.org/web/20151208064344/http://www.godrej.com/godrej/PrecisionSystems/Pdf/semi_cryogenic_engines.pdf |archive-date=2015-12-08 }}</ref><ref>{{Cite web |date=2019-09-19 |title=ISRO moves on, gears up to test semi-cryogenic engine in Ukraine |url=https://www.thehindubusinessline.com/news/science/isro-moves-on-gears-up-to-test-semi-cryogenic-engine-in-ukraine/article62242148.ece |access-date=2023-07-03 |website=www.thehindubusinessline.com |language=en}}</ref>

With the SE-2000 and an uprated [[CE-20]], the LVM3's cargo capacity will increase from 4 to 5 tons in [[Geostationary transfer orbit|GTO]]. The propellant feeding system of the SE-2000 provide pressures of up to 600 [[Bar (unit)|bar]], while the chamber pressure is 180 bar.<ref>{{Cite news |last=Kumar |first=Chethan |date=2025-03-29 |title=Isro achieves milestone in semi-Cryo engine development with key test |url=https://timesofindia.indiatimes.com/india/isro-advances-semi-cryogenic-engine-development-with-successful-key-test-/articleshow/119697593.cms |access-date=2025-03-30 |work=The Times of India |issn=0971-8257}}</ref>

== Development and testing ==

=== Development tests ===
* '''10 May 2023:''' First integrated test of 2000 kN semi-cryogenic engine on an intermediate configuration was conducted at Semi cryogenic Integrated Engine & Stage Test (SIET) facility in [[ISRO Propulsion Complex]] (IPRC). During the test, complex chill-down operations were performed to meet necessary conditions for engine start.<ref>{{Cite web |title=Tests commenced on Semicryogenic engine at IPRC, Mahendragiri |url=https://www.isro.gov.in/First_Integrated_Test_SemicryogenicEngine.html |access-date=2023-05-10 |website=www.isro.gov.in |quote=This test demonstrated the complex chill-down operations spanning about 15 hours duration that was conducted successfully, meeting all the required conditions for engine start.After the chill down of the LOX circuit, the feed circuit of kerosene was filled, and LOX was admitted into the gas generator by opening the injection valve. Successful performance of the test article helps derive the sequence of operations for further tests.}}</ref>

*'''1 July 2023:''' First hot test with intermediate configuration of the semi-cryogenic engine, known as Power Head Test Article (PHTA) was conducted at SIET facility. The test proceeded nominally till 1.9 seconds validating the ignition and subsequent performance of PHTA. At 2.0 seconds, an unexpected spike in the turbine pressure and subsequent loss of turbine-speed was observed. The test was terminated mid-way as a precaution. The intended duration of test was 4.5 seconds to validate the performance of the gas generator, turbo pumps, pre-burner and control components with focus on the ignition and hot-gas generation within the pre-burner chamber.<ref>{{Cite web |title=First hot test of the Semi-cryogenic engine conducted at IPRC, Mahendragiri |url=https://www.isro.gov.in/First_Hot_Test_SemicryogenicEngine.html |access-date=2023-07-03 |website=www.isro.gov.in}}</ref>

* '''2 May 2024:''' First ignition trial of Pre-burner Ignition Test Article (PITA) was conducted nominally at SIET facility. PITA is a full complement of the engine power head system but without turbo pumps.<ref>{{Cite web |title=Successful ignition test on Semi Cryogenic Pre-Burner Ignition Test Article (PITA) |url=https://www.isro.gov.in/Successful_ignition_test_on_semi_cryogenic_PITA.html |access-date=2024-05-06 |website=www.isro.gov.in}}</ref> It was proved that the pre-burner could ignite smoothly and continuously. A start fuel ampule that combines [[triethylaluminium]] and [[Triethylborane|triethyleboron]] created by [[Vikram Sarabhai Space Centre]] (VSSC) is used to ignite semi-cryogenic engine and utilized for the first time in ISRO's 2000 kN semi-cryogenic engine. For characterization, injector elemental level ignition tests were carried out at the VSSC Propulsion Research Laboratory Division (PRLD). Additionally, work is being done on the creation of a semi-cryogenic stage that can load 120 tons of propellant.<ref>{{Cite web |last=Pillai |first=Soumya |date=2024-05-06 |title=ISRO completes key test for India's first semi-cryogenic engine to better future launches |url=https://theprint.in/science/isro-completes-key-test-for-indias-first-semi-cryogenic-engine-to-better-future-launches/2072217/ |access-date=2024-05-07 |website=ThePrint |language=en-US}}</ref>

=== Hot tests of Power head Test Article (PHTA) ===
* '''28 March 2025:''' PHTA underwent its first successful hot test at the IPRC to validate the propellant feed system's design, comprising the low- and high-pressure turbo-pumps, the pre-burner, the starter system, and the control components. Over the course of the 2.5 seconds test, the engine's seamless ignition and boost strap mode operation were demonstrated.<ref name=":0">{{Cite web |date=2025-03-28 |title=ISRO achieves major breakthrough in Semicryogenic Engine development |url=https://www.isro.gov.in/ISRO_achieves_breakthrough_in_Semicryo_engine_development_Mar_2025_Final.html |access-date=2025-03-30 |website=www.isro.gov.in}}</ref> All of the engine parameters were as expected.

* '''24 April 2025:''' PHTA underwent second hot test for 3.5 second duration, validating the engine start-up sequence and demonstrating stable and controlled performance.
