Semi-Cryogenic Engine
- The Indian Space Research Organisation on Wednesday successfully carried out the first test of a semi-cryogenic engine at the newly commissioned Semi-cyrogenic Integrated Engine and Stage Test Facility at the ISRO Propulsion Complex (IPRC) in Mahendragiri, Tirunelveli district.
- It was the first integrated test on an intermediate configuration of the 2000kN semi-cryogenic engine.

Semi-Cryogenic Engines
- Semi-cryogenic engines are a type of rocket engine that use a combination of liquid and gaseous propellants. They are called “semi-cryogenic” because they operate at temperatures higher than cryogenic engines but still colder than traditional liquid rocket engines.
- A semi-cryogenic engine uses refined kerosene instead of liquid hydrogen. Liquid oxygen is used as an oxidizer.
- The Semi Cryogenic Propulsion System Project envisages the design and development of a 2000 kN semi-cryogenic engine and ‘SC120 stage’ that will enable the development of a heavy-lift capability for future Indian space transportation systems.
