GSLV- MkIII L110 Liquid Core Stage Test Fired by ISRO

Indian Space Research Organisation conducted the static test of its liquid core stage (L110) of GSLV Mk III launch vehicle, for 150 seconds at its Liquid Propulsion Systems Centre (LPSC) test facility at Mahendragiri at 16:00 hrs on March 5, 2010.

Indian Space Research Organisation conducted the static test of its liquid core stage (L110) of GSLV Mk III launch vehicle, for 150 seconds at its Liquid Propulsion Systems Centre (LPSC) test facility at Mahendragiri at 16:00 hrs on March 5, 2010.

While the test was originally targeted for 200 seconds it was stopped at 150 seconds since a deviation in one of the parameters was observed. About 500 important parameters were monitored during the static test. The next static test for 200 seconds will be conducted after analysis of this data. GSLV Mk III launch vehicle is being developed for launching 4 tonne class of satellites in Geo-synchronous Transfer Orbit (GTO).

Measuring 17 meters in length and 4 meters in diameter, L110 is an earth storable liquid propellant stage with propellant loading of 110 tonnes. L110 stage uses two high-pressure Vikas engines in a clustered configuration and draws its heritage from the second stage of PSLV and GSLV and strapons of GSLV.

While in PSLV and GSLV, the liquid stage with single engine configuration burns for 150 seconds, the GSLV-MkIII requires burning for 200 seconds in a twin engine configuration.
