The Indian Space Research Organisation (ISRO) has achieved a significant milestone in its Semicryogenic Engine development. The space agency announced that it successfully conducted a hot test of the intermediate configuration of its powerful 2000 kN Semicryogenic engine, designated as the Power Head Test Article (PHTA), at the ISRO Propulsion Complex, Mahendragiri.
Successful PHTA Hot Test Marks a Major Step
The PHTA test demonstrated the integrated performance of all crucial engine systems, including:
- Turbopumps
- Pre-burner
- Start-system
- Control components
Notably, this test configuration did not include the thrust chamber, which will be part of future evaluations. The test results aligned with ISRO’s expectations, further solidifying confidence in the engine’s design and functionality.
Boosting India’s Space Capabilities
The successful test brings ISRO closer to achieving a high-thrust Semicryogenic propulsion system. Once fully operational, this engine will significantly enhance the payload capacity of the LVM3 launch vehicle, increasing its ability to transport payloads from 4 tonnes to over 5 tonnes to the Geostationary Transfer Orbit (GTO). This development is a major step forward for India’s space ambitions, making future missions more efficient and cost-effective.
What’s Next for ISRO?
With this breakthrough, ISRO moves closer to the realization of its Semicryogenic propulsion system, a crucial technology that will support upcoming deep-space missions, satellite launches, and human spaceflight programs. The agency is expected to continue further testing and integration, paving the way for enhanced launch capabilities in the near future.
