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]

The ISRO suspects that the failure was caused by the third stage not igniting.

Human-rating certification, also known as man-rating or crew-rating, is the certification of a spacecraft or launch vehicle as capable of safely transporting humans. There is no one particular standard for human-rating a spacecraft or launch vehicle, and the various entities that launch or plan to launch such spacecraft specify requirements for their particular systems to be human-rated.

Test Vehicle Abort Mission-1 (TV-D1) was a high altitude abort test performed as part of the Gaganyaan program, initially set to be held on 21 October 2023 at around 02:30 UTC. Liftoff was delayed to 03:15 UTC due to weather issues, and five seconds before launch it was put on hold by the on-board computer due to an engine anomaly, as reported in ISRO's mission livestream. The launch occurred at 04:30 UTC, and the crew module successfully separated from the launch vehicle. The crew module was successfully recovered by the Indian Navy. India is the fourth country, after Russia, the United States, and China, to successfully test this technology.
