The CE-20 is a cryogenic rocket engine developed by the Liquid Propulsion Systems Centre (LPSC), a subsidiary of the Indian Space Research Organisation (ISRO). It has been developed to power the upper stage of the LVM3.[5] It is the first Indian cryogenic engine to feature a gas-generator cycle.[6] The high thrust cryogenic engine is the most powerful upper stage cryogenic engine in operational service.[7]

Overview

The CE-20 is the first Indian cryogenic engine to feature a gas-generator cycle.[8] The engine produces a nominal thrust of 200 kN, but has an operating thrust range between 180 kN to 220 kN and can be set to any fixed values between these limits. The combustion chamber burns liquid hydrogen and liquid oxygen at 6 MPa with 5.05 engine mixture ratio.[3][4] The engine has a thrust-to-weight ratio of 34.7 and a specific impulse of 442 seconds (4.33 km/s) in vacuum.[2]

Development and Testing

Manufacturing

The CE-20 cryogenic engine is manufactured by Hindustan Aeronautics Limited at its Integrated Cryogenic Engine Manufacturing Facility (ICEMF) in New Tippasandra, a suburb of Bengaluru.[39]
