ISRO has reached a significant milestone in its mission to pioneer space exploration. The Indian Space Research Organisation announced that its CE20 cryogenic engine has successfully undergone rigorous testing in ambient conditions. This achievement is a crucial stepping stone for upcoming missions.
On November 29, the CE20 engine, designed to support the upper stage of the Launch Vehicle Mark-3 (LVM-3), was hot-tested at the ISRO Propulsion Complex in Tamil Nadu. With a nozzle area ratio of 100, this engine has been crucial in powering six successful LVM3 missions to date. Furthermore, the engine’s thrust capabilities have been enhanced, being recently certified for the Gaganyaan mission, India’s first manned space endeavor.
The testing process was no small feat. The high-area ratio nozzle operates at a pressure as low as 50 mbar, creating challenges like potential flow separation, which could lead to damaging vibrations. To ensure robust performance, ISRO has been executing acceptance tests at the High-Altitude Test facility, which adds layers of complexity to their testing procedures.
In a groundbreaking approach, engineers developed an innovative Nozzle Protection System to streamline testing at sea level, significantly reducing both cost and complexity. Additionally, the recent tests focused on the intricate process of cryogenic engine restart capabilities, showcasing ISRO’s determination to advance India’s space exploration ambitions while ensuring the reliability of its technologies.
