GSLV with cryogenic engine

By
GSLV-Geosynchronous Satellite Launch Vehicle::

The Geosynchronous Satellite Launch Vehicle is an expendable launch system developed and operated by the Indian Space Research Organisation (ISRO) to launch its INSAT-type satellites into geostationary orbit to make India independent on foreign rockets launchers.

To know more i too digged a lot for you i want to share it with you..
Unlike PSLV that
GSLV's main features is that
    -it Uses CRYOGENIC ENGINE,can develop more thrust and consequently take heavier satellites to      36,000 km above the Earth.Lets see what it featured on./

Main Features::
The GSLV improved by overall performance of the PSLV with addition of liquid 'strap on' boosters and the most cryogenic upper stage Engine.

It is a three-stage launch vehicle with
-the first stage being solid-propelled,
-the second liquid-propelled (with hypergolic fuels) and
-the final stage being liquid propelled as well (with cryogenic fuels).

Therefore, ISRO developed the cryogenic engine used in the GSLV indigenously.
The GSLV can place or position approximatly 5000 kg into an east'erly lower Earth orbit.
Using the Russian 12KRB upper stage, with KVD-1 cryogenic rocket engine, GSLV can place 2200 kg (4,850 lbm) into an 18 degree geostationary transfer orbit.

Three Stages plays major role and each one have its one limit to bound.

First Stage:
S139 stage is 2.8 m in diameter and which is made up of M250grade maraging steel(i think might be more strong to bare the extreme heat during ignition) and it has a nominal propellant loading of 139 tonnes of fuel in it..
oh..

Second Stage:
This stage is powered by the Vikas engine.The booster has 2.8 m diameter and uses 37.5 metric tonnes of liquid propellant as fuel and nitrogen tetroxide(N2O4) as oxidizer, in two aluminium alloy compartments separated by a common bulk head. It delivers 720 kN (160,000 lbf) of thrust.
KN-Kilo Newton.

Third Stage:
This is the final stage and its propelled by the most powerful ROcket Engine,by a cryogenic rocket engine,it is is 2.8 m in diameter and uses                
liquid hydrogen (LH2) and
liquid oxygen (LOX)
in two separate tanks of aluminium alloy.Propellant loading capacity is 12.5 tonnes of fuel.

>>The indigenous cryogenic engine was built in Tamil Nadu at the Liquid Propulsion Systems Centre.<<
i'm happy to say its built on my soil..tamilan.
