Introduction

GSLV-Mk-3, or GSLV-III, is being developed to launch up to 4 tons into geosynchronous transfer orbit and up to 10 tons in low Earth orbit.

Weight 629 ton
Height
49 m
GTO Weight
10 ton
GEO Weight
4.5 - 5 ton

GSLV-Mk III will launch a four ton payload into geosynchronous transfer orbit and up to 10-ton satellites in low Earth orbit.

Its payload fairing has a diameter of 5 m and is 5m heigh. It will provide for about 110 cubic meter of payload volume.

The launcher is under development with a $500 million budget and a Russian cryogenic stage, which will eventually be replaced with an Indian Cryogenic Engine (ICE).

The launcher is not a derivative of GSLV. It is a completely new design.

It will eventually be used for the Indian manned space flight program, allowing the Indian Manned Spacecraft to carry three astronauts instead of two using the GSLV Mk II.
Configuration

It is a three-stage launcher with a 110 ton restartable core liquid propellant second stage (L-110) using two Vikas engines, a strap-on first stage with two solid propellant S-200 motors, each with 200 ton propellant, and a cryogenic upper stage with a propellant loading of 25 ton (C-25).
First Flight

A sub-orbital flight test of the launcher, sans its cryogenic third stage, is planned for December 2012. If the test is successful, the launcher will start orbital flights in 2014. [via NASASpaceflight.com]

In Jan-Feb 2012, ISRO fully assembled a GSLV Mk3 in Sriharikota and integrated it on the second launch pad. A series of tests were done followed by a detailed review by experts. [via Deccan Herald]

The launcher was initially expected to become operational by 2010/2011 with first flight in 2009-10.

The failure of ISRO developed cryogenic upper stage on April 15, 2010 has led to a prolonged delay in the first flight of GSLV Mk-3.

Addressing the National Technology Summit in New Delhi on June 7, ISRO Chairman K Radhakrishnan said ISRO will test the GSLV Mk-3 in two years.

"In the next two years, we are looking to begin the flight-testing of the GSLV Mk III engine, which will be the third-largest in the world," he said.

Speaking to the press on April 28, 2011, M. Chandradathan, Director, Sathish Dhawan Space Centre, Sriharikota, said that the launcher would be ready by the end of 2012 and it would be tested next year.

“GSLV-Mk III has three stages. The first stage, Solid propellant booster S-200 has been tested and qualified; Second and liquid propellant stage called L-110 has also been tested. Work is yet to be completed in third and important stage, the cryogenic stage,” he said.

L-110 Core Stage Development

The L-110 core stage measures 17 metres in length and four metres in diameter.

The two Vikas engines used in the stage also serve as the second stage of PSLV and GSLV.

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

First Static Test

A test of the L-110 core stage was conducted on Saturday, March 6, 2010, at the the Liquid Propulsion Systems Centre (LPSC) at Mahendragiri near Nagercoil in Tamil Nadu, where a huge test rig has been erected.

The test firing was planned for 200 seconds but had to be aborted at 150 seconds due to a deviation in one of the 500 parameters being monitored.

The test will be repeated after an analysis of the data gathered from the first test.

Second Static Test

A second 200 sec static test of the L-110 was successfully conducted on Wednesday, September 8, 2010

S-200 motor

The S-200 motors (200 ton propellant, 25m) are the third largest solid propellant boosters in the world - after the US Space Shuttle’s booster (440 ton, 37.8m) and Europe’s Ariane (240 ton, 31.6m)

They are being manufactured in a largely automated plant in Shreeharikota built by Indian engineers and industry.

Measured in terms of diameter, the S-200 ranks second in the world with 3.2m, with the while Space Shuttle and Ariane measuring 3.6 m and 3.05 m respectively.

The S-200 motors have a fuel burn time of 103 secs, against Ariane's 130 sec and Space Shuttle booster's 123 sec.

The S-200 will be ground tested at India's space port Satish Dhawan Space Centre, Sriharikota, 80 km from Chennai during the third week of January 2010.

The solid rocket under development for Ares1 will eventually become the heaviest solid propellant rocket motor with a diameter of 3.77m, length of 52m, propellant capacity of 625 ton and a burn time of 123 seconds.

S-200 Test Firings


The S-200 was tested with a 130 sec burn on Sunday, January 24, 2010 at the Satish Dhawan Space Centre (SDSC), Sriharikota. The motor produced a peak thrust of 500 tons.

N. Narayana Moorthy, Project Director, GSLV Mk-III, called the test a big success. Over 600 parameters were monitored during the test.
 
I was under the perception that MK-iii is taking so long since the cryogenic engine was going to be indigenous ? The article says it's from russia ?

#btw a very very good development

but i thought they are going to use indigenous cryogenic engine.
 
but i thought they are going to use indigenous cryogenic engine.

the gslv mk3 has a 2000kN semi cryogenic engine which is in advanced stages of development and will soon be test fired. i think for the first flight they dont wanna use the indegeneous one. the 2010 incident is still alive in their minds i guess.

Good luck ISRO. GSLV has to succeed this time :tup: :victory:
 
why just third largest? we should build largest after this. No need to go slow. :tup:
 
why USA???
because they denied us the tech and didnt even let us get it from russia. yes it indeed is a true middle finger to usa. us space program is dying a slow death and nothing can stop india.

nah...you too know that the kind of ban we faced after 1998 nuclear test is merely some tech denial(see the amount of blockade NK faced after nuclear and missile test).they already starting to co-operate on various techs.and the boon of the ban is,many techs we built ourselves.no need to curse USA on that.
 
so how come after the US restrictions on Russian cryogenic engines, we still have a cryogenic engine to fit into MK-III ?
