Technical Problems of GSLV

The Government has sorted out the technical problems of Geosynchronous Satellite Launch Vehicle (GSLV) which may carry heavy satellites and put them into orbit. The earlier flights GSLV-F02 on July 10, 2006, GSLV-D3 on April 15, 2010 and GSLV-F06 on December 25, 2010 could not accomplish the mission objectives due to technical problems. In GSLV-F02 flight, the primary cause of mission failure has been the loss of thrust in one of the liquid strap-on motors of the first stage. The anomalous behavior was attributed to the malfunctioning of propellant regulator of the gas generator system in this strap-on motor. The GSLV-D3 flight, with indigenous cryogenic upper stage, failed as the indigenous cryogenic engine after its ignition couldn’t sustain the combustion beyond 1 second, due to the anomalous stoppage of Fuel Booster Turbo Pump. In GSLV-F06 flight, with Russian cryogenic upper stage, the primary cause of the failure was the untimely and inadvertent snapping of a group of ten connectors located at the bottom portion of the Russian Cryogenic Stage, due to structural failure of the Lower Shroud. Based on the suggestions made by the failure analysis committees, ISRO has implemented the modifications and improvements in GSLV, which include independent inspection and quality checks for all critical components and sub-assemblies, change of bearing housing material, revision of tolerances and seal clearances of Fuel Booster Turbo Pump of Cryogenic Engine, redesign of the Cryogenic Stage Lower Shroud, revision of connector mounting scheme and wire tunnel configuration. After implementing the modifications and improvements in GSLV, the next flight GSLV-D5 was successfully launched on 5th January 2014 from Satish Dhawan Space Centre, Sriharikota. India has prepared its own indigenous cryogenic engines meant for GSLV and flown in GSLV-D3 and GSLV-D5. Cryogenic engine required for next flight GSLV-D6 is also prepared and is undergoing acceptance testing. This was stated by Union Minister of State for Science and Technology and Ministry of Earth Sciences, D/o Atomic Energy and D/o Space Dr. Jitendra Singh in a written reply in Rajya Sabha today.  You like My Reporting?
