ISRO Mahendragiri semi-cryogenic engine test: 200-ton thrust milestone for S2000 engine
ISRO’s Mahendragiri centre successfully tested a semi-cryogenic engine power head at full 200-ton thrust, a key step for the S2000 engine.
Key highlights
Direct fact
In September 2026, ISRO’s Mahendragiri centre in Tirunelveli district successfully tested a semi-cryogenic engine Power Head Test Article (PHTA) at full 200-ton thrust for 35 seconds.
Key specifics
- The test was the 9th stage in the development sequence of the next-generation semi-cryogenic engine.
- Earlier thrust trials had reached 47% (94 tonnes), 60% (120 tonnes) and 88% (175 tonnes).
- The engine is linked to the S2000 engine, which has a capacity of 2,000 kilo Newton.
- ISRO said the engine can carry heavier satellites into orbit.
- The propellants used are liquid oxygen and highly refined kerosene.
