ISRO successfully conducts static testing of GSLV-Mk III rocket

Six months after a failed test, the Indian Space Research Organisation (ISRO) successfully conducted the second static testing of its liquid core stage (L110) of Geosynchronous Satellite Launch Vehicle Mark III (GSLV Mk -III), according to a press release.

GSLV-Mk III, which is currently under advanced stage of development, uses two solid strap-on boosters (S200), L110 liquid stage and a cryogenic upper stage C-25

The test lasted 200 seconds at ISRO's Liquid Propulsion Systems Centre (LPSC) test facility at Mahendragiri today (September 8, 2010) at 15:50 hrs.

L110 is one of the heaviest earth storable liquid stages ever developed by ISRO. L110 stage had two high pressure Vikas engines in a clustered configuration. Nearly 500 health parameters were monitored during the test and the initial data acquired indicates its normal performance.

Today’s successful test of L110 for its full flight duration of 200 seconds, is a major milestone in the earth storable liquid rocket programme of ISRO and a significant step forward in the development of GSLV-Mk III launch vehicle.

ISRO conducted the test for 150 seconds at LPSC test facility on March 5 this year. While the test was originally targeted for 200 seconds it was stopped at 150 seconds since a deviation in one of the parameters - minor leakage in the command system - was observed. It may be recalled that GSLV-Mk III, which is currently under advanced stage of development, uses two solid strap-on boosters (S200), L110 liquid stage and a cryogenic upper stage C-25.
