BENGALURU: Indian Space Research Organisation (Isro) on Thursday said it has successfully completed the hot test of cryogenic engine for the GSLV-F11 , which is scheduled to launch GSAT-7A in November this year.

A hot test is a ground test to check the safety and efficiency of the engine. It was conducted on Monday at Isro Propulsion Complex in Mahendragiri for 200 seconds during which the engine operated in the nominal and 13% uprated thrust regimes.

“All the propulsion parameters were found to be satisfactory. For the first time, indigenously developed copper alloy was used in the engine,” an Isro spokesman said.

The cryogenic engine will now be integrated with the propellant tanks, stage structures and associated fluid lines to realise the fully integrated flight cryogenic stage.
