Cryogenic engine undergoes ground test

Bangalore, Aug 4 (UNI) The indigenously developed cryogenic engine, to be used as the upper stage of India's Geosynchronous Satellite Launch Vehicle (GSLV),today underwent ground tests for a duration of eight minutes at the Liquid Proplusion Test Facility at Mahendragiri in Tamil Nadu.

The earlier test was for a shorter duration of 50 seconds. Today's successful test constituted a major milestone towards qualification of the stage, an ISRO release said here tonight.

Liquid Propulsion Systems Centre was the lead centre for the development of Cryogenic Upper Stage with the involvement of other ISRO centres,including Vikram Sarabhai Space Centre, Thiruvananthapuram, ISRO Satellite Centre in Bangalore and Satish Dhawan Space Centre SHAR in Sriharikota that developed various components and systems.

Several industries, both in public and private sector, were also involved in its development.

The indigenous cryogenic engine had successfully logged cumulative tests duration of 6000 seconds as part of its qualification programme. Today's long duration test had validated the design, robustness and performance adequacy of the engine and the state for its use in the GSLV, it added.
