September 27, 2023

ISRO successfully completed the CE20 E13 engine hot test for the Gaganyaan qualification and 22-tonne thrust qualification.

LVM3 is configured as a three stage vehicle with two solid strap-on motors (S200), one liquid core stage (L110) and a high thrust cryogenic upper stage (C25).

The engine developed by the Liquid Propulsion Systems Centre (LPSC), Valiamala was tested at ISRO Propulsion Complex (IPRC), Mahendragiri, Tamil Nadu.
The CE20 engine is a vital component, serving as the powerhouse of the Cryogenic Upper Stage (CUS) responsible for propelling the upper stage (C25) of the Launch Vehicle Mark-3 or LVM3 vehicle.
It has demonstrated its capability by successfully operating at a thrust level of 19 tonnes in six successive LVM3 missions, including the Chandrayaan-2, Chandrayaan-3, and two commercial OneWeb missions.
The CE20 engine hardware referred to as E13 was selected for both Gaganyaan qualification and 22-tonne thrust level operations.
