Key test for ISRO’s GSLV Mark III rocket successful

Chennai : Indian Space Research Organisation (ISRO) on Wednesday successfully conducted a long-duration static test of a crucial liquid core stage for a new generation heavy rocket- GSLV Mark III.

The second static testing of ISRO’s liquid core stage (L110) of Geosynchronous Satellite Launch Vehicle Mark III (GSLV Mk -III) was conducted for 200 seconds at 3-50 pm in southern Tamil Nadu’s Mahendragiri.

The test was conducted at the ISRO’s Liquid Propulsion Systems Centre (LPSC) , an ISRO release said.
The GSLV-III or Geosynchronous Satellite Launch Vehicle mark III is a launch vehicle currently under development by the ISRO. It is intended to launch heavy satellites into geostationary orbit, and will allow India to become less dependent on foreign rockets for heavy lifting.

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.

Wednesday’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.

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.
