Indian Space Research Organization . It is intended to launch heavy satellites intogeostationary orbit , and will allowIndia to become less dependent on foreign rockets for heavy lifting.The rocket is the technological successor to the
GSLV , however is not derived from its predecessor. There is no GSLV-II - the GSLV-I has a Russian-made cryogenic third stage, which was to be replaced with an identical Indian-built one for the GSLV-II. US objections based on theMissile Technology Control Regime (MTCR) prevented the Russia-India technology transfer that would have enabled this, leading to cancellation of the GSLV-II. The GSLV-III will use an Indian-developed cryogenic engine. [ [http://www.hindu.com/thehindu/holnus/008200708050320.htm Cryogenic stage tested on the ground] ]The maiden flight is scheduled for
2008 .tages
Boosters
The boosters used on the GSLV-III will be the S200, which is also designated Large Solid Booster, or LSB, which is a solid propellant stage with a mass of 200 tonnes. Two boosters will be used. Each has a diameter of 3.4 metres and a length of 25 metres. They are estimated to produce 785 tonnes-force (7.70 MN) of thrust.
Core stage
The core stage will be the L110 restartable liquid stage which has 110 tonnes of liquid propellant and a diameter of 4-metres. It will be the first Indian liquid engine cluster design, and will use two improved Vikas engines, each producing 75 tonnes (735 kN) of thrust. The improved Vikas engine will use regenerative cooling, providing improved weight and
specific impulse , compared to earlier rockets.Upper stage
The upper stage will be the C25, which is a restartable cryogenic stage fuelled by 25 tonnes of
liquid oxygen andliquid hydrogen . It has a 4-metre diameter and is 8.2 metres long. The stage will produce 20 tonnes (197 kN) of thrust.ummary
