India’s Space Ambitions Get a Boost

The Indian Space Research Organisation (ISRO) has marked a significant milestone with the successful sea level hot test of its CE20 cryogenic engine. This innovative engine is crucial for upcoming space missions as it features advanced restart-enabling systems, making it a centerpiece of India’s space exploration efforts.

Conducted at the ISRO Propulsion Complex in Mahendragiri, Tamil Nadu, on November 29, this test unveiled new challenges related to the engine’s high area ratio nozzle, which operates under a low exit pressure of about 50 mbar. Notably, ISRO identified flow separation within the nozzle as a primary concern that could lead to intense vibrations and potential thermal damage.

To address these complications, ISRO has introduced an innovative Nozzle Protection System during this sea level testing. This new approach simplifies acceptance testing and reduces costs, making the process more efficient without compromising safety. Past tests have already demonstrated the engine’s ability to ignite in a vacuum without closing the nozzle, showcasing robust engineering.

The CE20 cryogenic engine, developed by the Liquid Propulsion Systems Centre, currently powers the upper stage of the Launch Vehicle Mark-3 (LVM3) and has shown an impressive capability of achieving up to 22 tonnes of thrust, paving the way for India’s ambitious Gaganyaan mission and beyond. This success is a testament to ISRO’s commitment to enhancing its payload capabilities and expanding its presence in space exploration.
