Indian Space Research Organisation recently conducted a successful sea-level hot test of indigenously developed CE20 Cryogenic Engine. This represents a significant leap in India’s rocket propulsion technology and underlines its readiness for advanced missions.

Key Features of the CE20 Cryogenic Engine

Indigenous Development: Designed and developed by the Liquid Propulsion Systems Centre (LPSC) of ISRO.

Operational Use: Powers the upper stage of the LVM3 (Launch Vehicle Mark-3), India’s heaviest operational launch vehicle. Qualified for operation at a thrust level of 19 tonnes, and has successfully powered six LVM3 missions so far.

Enhanced Capabilities:

• Recently upgraded for the Gaganyaan mission, with an increased thrust level of 20 tonnes.
• Further uprated to 22 tonnes for the C32 stage, aimed at enhancing the payload capability of LVM3.

Innovative Features:

• Equipped with a Nozzle Protection System, simplifying complexities in engine testing.
• Achieved successful testing of a nozzle area ratio of 100.
• Tested a multi-element igniter by activating only its first element to ensure engine safety and performance.

Achievements of the Recent Test

• Engine Performance: Confirmed normal functionality of the engine and its testing facilities.
• Significant Milestones: Evaluated new technologies, such as an enhanced igniter system, and validated the engine for its upgraded thrust capacity.
