ISRO Successfully Conducts Sea Level Hot Test of Advanced Cryogenic Engine

Thiruvananthapuram, India - November 29, 2024: The Indian Space Research Organisation (ISRO) has successfully completed a sea level hot test of its cutting-edge CE20 Cryogenic Engine at the ISRO Propulsion Complex in Mahendragiri, Tamil Nadu. This milestone achievement marks an important step forward in the development of India's space exploration capabilities.

The test, which took place on November 29, 2024, showcased the engine's performance under conditions that simulate sea level, a challenging environment due to the high area ratio nozzle used in the CE20 engine. The nozzle has an exit pressure of approximately 50 mbar, posing significant technical difficulties during testing.

According to ISRO officials, one of the key objectives of the test was to demonstrate the performance of a multi-element igniter required for engine restart capability. This aspect is crucial for ensuring the stability and reliability of the engine in various operational scenarios.

The successful completion of this test paves the way for further development and validation of the CE20 engine at higher altitudes, as initially planned. The flight acceptance tests will now be conducted at the High-Altitude Test (HAT) facility, adding complexity to the acceptance testing procedure. However, ISRO officials are optimistic about meeting the technical requirements for the engine's successful integration into future space missions.

The CE20 Cryogenic Engine is a crucial component in various ISRO projects, including the upcoming commercial launch vehicle program. India's thriving space industry has been making significant strides in recent years, and this achievement is expected to play a pivotal role in furthering its aspirations.
