ISRO tests liquid stage propellants system of GSLV Mk –III

The Indian Space Research Organization (ISRO) has successfully tested the second static testing of its liquid core stage (L110) of the Geosynchronous Satellite Launch Vehicle Mark III (GSLV Mk -III) at the Liquid Propulsion Systems Centre (LPSC) test facility at Mahendragiri, on Thursday.

The test carried on for 200 seconds which is also the full duration of the flight. The L110 is one of the heaviest liquid stages developed by the agency, had two high pressure Vikas engines in a clustered configuration.

The GSLV-Mk III uses two solid strap-on boosters (S200), L110 liquid stage and a cryogenic upper stage C-25. The launcher is expected to be ready for a first flight in 2012.

Engineers monitored the stage on 500 health parameters during the test and according to the initial reports the performance was normal. The successful testing of the stage is an important achievement for the earth storable liquid rocket programme of the agency and also an important step to forward the project to develop GSLV-Mk III launch vehicle.

“Today's successful test of (the liquid second stage) L110 for its full flight duration of 200 seconds is a major milestone in the Earth storable liquid rocket programme and a significant step forward in the development of GSLV-MkIII launch vehicle,” the agency said in a release.

The stage was tested successfully for full flight duration of 200 seconds. The agency had earlier tested it for 150 seconds at LPSC test facility on March 5 as it had to be stopped because of the deviation reported in one of the parameters.

"The GSLV-M III, has three propulsion elements that give power to the rocket. The first one is solid motor... solid means solid propellants used in the rocket motors. Two such rocket motors have been used. Then the second stage is the liquid stage that will be tested today, and the third stage is the cryogenic stage which we are developing," said ISRO chief K. Radhakrishnan.
