ISRO Project Code Named ‘SCE 200’

IAS Prelims 2023

The SCE-200 is an Indian liquid-fuel rocket engine burning LOX and kerosene in a oxidizer-rich staged combustion cycle.

It is being developed by the Liquid Propulsion Systems Centre, a subsidiary of India’s space agency ISRO, 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 SC200.

The primary goal of ISRO will be bringing in a new family of launch vehicles called ULV (Unified Launch Vehicle) by replacing currently operational PSLV, GSLV and GSLV Mk III.

The ULV (Unified Launch Vehicle) marks the renunciation of India for N2O4/UDMH as propellant for space launch vehicle systems.

The Indian Space Research Organisation (ISRO) 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.

The semi-cryogenic engine uses a combination of liquid oxygen (LOX) and refined kerosene (Isrosene) as propellants.
