Quote from: Salo on 12/16/2010 11:38 amGSLV-F06 will fly with russian C15 upper stage. It is a first indo-russian GSLV MkII.I was under the impression that what made the GSLV a Mark II was the use of the Indian upper stage.
GSLV MK II, earlier referred to as GSLV D3, will carry an Indian developed cryogenic third stage which will eventually be capable of launching 2,500 kg into Geostationary Transfer Orbit (GTO). The cryogenic engines that have powered the GSLV rocket so far were sold to India by Russia. Of the seven cryogenic engines supplied, five have now been used. Eventually, all future GSLV's will use the Indian Cryogenic Upper Stage (CUS) that develops 9 ton of thrust against 7.5 ton of the Russian CUS and carries 15 ton of propellant against 12.5 ton.
GSLV rocket now taller, heavierChennai, December 17, 2010First Published: 15:02 IST(17/12/2010)India's geosynchronous satellite launch vehicle (GSLV), scheduled to blast off on Monday with an advanced communication satellite (GSAT-5P), is now taller by two metres and heavier by four tonnes as compared to its standard configuration. The Indian Space Research Organisation's standard configuration for the GSLV rocket is a height of 49 metres and 414 tonnes in weight at lift-off.The rocket that would lift off Monday stands 51 metres tall and weighs 418 tonnes.PS Veeraraghavan, director of the Vikram Sarabhai Space Centre, told IANS: "This time the fuel quantity for the cryogenic engine has increased and its thrust power has also gone up. The rocket will be carrying a heavier satellite (GSAT-5P) weighing 2,310 kg."The Russian made cryogenic engine will be powered with 15.2 tonnes of fuel (liquid hydrogen as fuel and liquid oxygen as oxidizer), an increase of around three tonnes, and the engine's length has also increased.The rocket has a bigger heat shield - four-metres in diameter and made of fibre reinforced plastic (FRP) - as compared to the standard configuration of 3.4-metre diameter made of aluminium alloy metal.With the changes in rocket's configuration, necessary calibrations have been carried out in the rocket's navigational systems, control dynamics and aerodynamics so that the flight is smooth and the mission is successful, a source associated with ISRO told IANS.Over the years, the carrying capacity of the GSLV has also increased -- from 1,530 kg in 2001 for GSAT-1 to 2,220 kg for GSAT-4 in April 2010.The latest has a payload of 2,310 kg with 36 transponders -- an automatic receiver and transmitter of communication or broadcast signals. Successful launch of the satellite will take the agency's transponder capacity to around 235 from 200 in orbit now.
The launch of the GSLV F06 with GSAT -5prime satellite on board, scheduled to take place on Monday (Dec.20) at 4 pm from Sriharikota has been postponed due to a minor leak in one of the valves of the Russian cryogenic stage. This leak was noticed during the pre-count down checks. The ISRO’s Launch Authorisation Board that met on Sunday at Sriharikota, therefore did not give the permission to go ahead with the 29 hr countdown which was to begin at 11am on Sunday. The date for the new launch will be announced after ISRO’s rocket technologists find the cause for the leak and take remedial action.
The GSLV-FO6 has major changes incorporated as compared to the previous flights. It includes the loading of 15 tonnes of propellants in its third stage of flight and the uprating of the third stage thrust by 26 per cent, ISRO said.
20/12/2010ISRO may take a call on GSLV mission tomorrowBangalore,Dec20 (PTI) Indian Space Research Organisation is expected to take a decision tomorrow on the fresh date for launch of GSAT-5P satellite on board Geo-Synchronous Satellite Launch Vehicle (GSLV-F06) after conducting an experiment to study the leak that led to the mission''s postponement.As of now, it appears to be a "liveable leak", an ISRO official told PTI here, a day after the space agency put off the launch from the spaceport of Sriharikota due to a "minor leak" in one of the valves of the Russian Cryogenic stage, observed during the pre-countdown checks."We are planning to do a small experiment tomorrow to ascertain the cause for the leak. If the leak is the same (as noticed during the pre-countdown checks), then we can go ahead with the launch. If the leak is increasing... beyond certain limits, then we have to stop (the mission)," the official said on condition of anonymity.If things are okay after verifications, ISRO might schedule the launch for Thursday, sources in the Bangalore-headquartered agency said.The 29-hour countdown planned to commence at 11 am yesterday had not been authorised by the Launch Authorisation Board that met in the forenoon to review the results of pre-countdown checks.
