The Indian Space Research Organisation (ISRO) has successfully completed the flight acceptance hot testing of the cryogenic engine designated for the sixth operational mission of the LVM3 launch vehicle (LVM-M6). 

 

The test was conducted at the ISRO Propulsion Complex in Mahendragiri, Tamil Nadu. The LVM3, also known as Launch Vehicle Mark-3, is a three-stage medium-lift launch vehicle developed by ISRO. 

 

The cryogenic engine of every mission undergoes hot testing as part of its acceptance process for the flight, ISRO said in a statement.

 

ISRO highlighted that the innovative test method significantly reduces the setup time and effort required for the flight acceptance test of a cryogenic engine, which in turn helps faster delivery of cryogenic stages for space missions. 

 

According to ISRO, the CE20 engine’s performance during the test met all objectives, with parameters closely aligning with predictions throughout the test duration. 

 

The engine will now be integrated into the Cryogenic Upper Stage of the LVM3-M6 mission, which is scheduled for the second half of 2025.
