ISRO Successfully Completes Sea-Level Hot Test of CE20 Cryogenic Engine
| Key Aspect | Details |
|---|---|
| Event | ISRO successfully conducted a sea-level hot test of the CE20 cryogenic engine. |
| Date of Test | November 29, 2024 |
| Location | ISRO Propulsion Complex, Mahendragiri, Tamil Nadu |
| Engine Details | CE20 cryogenic engine, developed indigenously by ISRO |
| Purpose of Test | Demonstrated restart-enabling systems and multi-element igniter performance |
| Challenges Addressed | Flow separation and nozzle vibrations, mitigated by a Nozzle Protection System |
| Current Thrust | 19 tonnes |
| Upgraded Thrust Plans | 20 tonnes for Gaganyaan mission, 22 tonnes for future C32 stage |
| Propellants Used | Liquid oxygen (LOX) and liquid hydrogen (LH2) |
| Temperature Requirements | LOX remains liquid below -183°C; LH2 remains liquid below -253°C |
| Significance | Boosts India's space exploration capabilities, reduces foreign dependence in cryogenic tech |
| Key Missions Powered | Chandrayaan-3, upcoming LVM3 launches, Gaganyaan, and interplanetary exploration |
