The indigenously developed cryogenic engine, to be used as the upper stage of India’s Geosynchronous Satellite Launch Vehicle (GSLV), on Saturday successfully cleared an eight minute ground test at the Liquid Propulsion Test Facility at Mahendragiri in Tamil Nadu.
The earlier test was for a shorter duration of 50 seconds. Saturday’s successful test constitutes a major milestone towards qualification of the stage, according to an ISRO release here.
It has validated the design, robustness and performance adequacy of the engine and the state for its use in the GSLV.
Lead centre
Liquid Propulsion Systems Centre was the lead centre for development of the Cryogenic Upper Stage with the involvement of other ISRO centres.
These include 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.
Cumulative tests
The indigenous cryogenic engine had successfully logged cumulative tests duration of 6000 seconds as part of its qualification programme.
Saturday’s long duration test has validated the design, robustness and performance adequacy of the engine and the state for its use in the GSLV.
