C20 cryogenic engine
ISRO has achieved an important success. The much awaited rocket engine C20 Cryogenic has successfully passed the test. Now soon this engine will make an important contribution in the future missions of the country. ISRO has successfully completed sea level hot test of its CE20 cryogenic engine with nozzle area ratio of 100 at ISRO Propulsion Complex, Mahendragiri, Tamil Nadu on 29 November 2024. The test also demonstrated the multi-element igniter required for engine restart capability.
Testing the CE20 engine at sea level poses significant challenges, primarily due to the high pressure ratio nozzle which has an exit pressure of approximately 50 mbar. The major concern during tests at sea level is flow separation inside the nozzle, which leads to severe vibrations and thermal problems at the flow separation bottom which can lead to possible mechanical damage to the nozzle. To mitigate this problem, flight tests for the CE20 engine are currently being conducted in a high-altitude test (HAT) facility, which adds to the complexity of the endurance testing process.
