The indigenously-built cryogenic engine was successfully tested in high altitude environment at the Liquid Propulsion Systems Centre (LPSC), Mahendragiri, on Wednesday evening, ISRO officials said here on Thursday.
The hot-test was conducted at the High Altitude Test Facility (HAT) at Mahendragiri in Tamil Nadu at 7.55 p.m. ‘’The performance of the cryogenic engine was as per prediction,’’ LPSC officials said in a statement.
The success of the test gives an immense boost to the prospects of the GSLV-D5 mission planned for July this year which plans to use the indigenously built engine, they said.
The engine uses a liquid oxygen and liquid hydrogen propellant combination developing a thrust of 7.5 tonnes and powers the cryogenic upper stage of the Geosynchronous Satellite Launch Vehicle (GSLV).
Developed by the LPSC, the engine has undergone ground tests, in sea level conditions, more than 30 times as part of development and qualification.
The directors of the Vikram Sarabhai Space Centre, LPSC, ISRO Inertial Systems Unit and other top ISRO officials were present.
