The GSLV-III or Geosynchronous Satellite Launch Vehicle mark III a current launch vehicle development project by the Indian Space Research Organization that got underway in the early-2000s and is now scheduled for its first suborbital test launch of the GSLV booster stage in 2014.^[5] It is intended to launch heavy satellites into geostationary orbit, and will allow India 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. The GSLV MK-1 had a Russian-made cryogenic third stage, this has been replaced with an Indian-built cryogenic stage for the GSLV MK-2. The GSLV MK-3 will have an Indian built cryogenic stage.^[6]^[7]

Vehicle Description

Boosters

The boosters used on the GSLV-III will be the S-200, 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 3.2 metres and a length of 25 metres. Each booster generates 560 tonnes-force (5.50 MN) of thrust at lift-off.^[8]

Core stage

The core stage will be the L-110 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.^[8] L110 is one of the heaviest earth storable liquid stages ever developed by ISRO.^[9]

Upper stage

The cryogenic upper stage will be the C-25, powered by the CE-20 engine, fueled by 25 tonnes of LOX+LH2. It will be 4 metres (13 ft) in diameter and 8.2 metres (27 ft) long. The stage will produce 20 tonnes (^{[convert: unit mismatch]}) of thrust.^[10]

Background

The C-25 upper stage of GSLV MK-3 is powered by the CE-20 cryogenic engine. This engine is slated for completion and testing by 2015, it will then be integrated with the C-25 stage and be put through a series of tests. The first C-25 stage will be used on the GSLV MK-3 D-1 mission in early 2017. This mission will put in orbit the GSAT19E communication satellite.^{[citation needed]} Work on the C-25 stage and CE-20 engine for GSLV Mk-3 upper stage was initiated in 2003, the project has been subject to many delays due to problems with ISRO's smaller cryogenic engine the CE-7.5 for GSLV MK-2 upper stage. After completion of CE-20 engine for GSLV MK-3 ISRO plans to start working on CE-60 and CE-100 cryogenic engines for future heavy lift vehicles being planned.^{[citation needed]}

Payload fairing

The payload fairing will have a diameter of 5 metres (16 ft) and a payload volume of 100 cubic metres (3,500 cu ft).^[10]^{[full citation needed]}

History

Development for the GSLV Mk III began in the early 2000s,^{[clarification needed]} with the first launch originally planned for 2009-2010. In the event, several factors have delayed the program, including the "failure of ISRO-developed cryogenic upper stage on April 15, 2010."^[5]

In 2007, wind tunnel tests were completed and vehicle aero-elastic test activities^{[clarification needed]} commenced. The vehicle configuration update was completed. All major facilities including propellant plant, vehicle assembly and integration building, mobile launch pedestal and facilities at work centers have reached^[when?] the final phase of completion.

First batch of light alloy structure and motor case segments were realized at work centers.^[when?] The avionics system designs have been completed and first batch of packages are being realized for qualification. Avionics assemblies layout has been finalized and integration trials for package assembly are being carried out.^{[citation needed]}

A suborbital flight test of the GLSV Mk3 launcher, without its cryogenic third stage, is planned for April 2014. With first flight now scheduled for April 2014; it is likely the first orbital flight will take place in 2016.^{[citation needed]} ISRO would then need several more successful launches to declare the launcher safe for manned flight. First manned flight is unlikely before 2020, possibly 2–3 years later.^[5]

S-200 Static test

The Solid booster S-200 was successfully tested in 24 January 2010. During the test, the S-200 booster was fired for 130 seconds and generated a peak thrust of about 500 tonnes. The performance of the booster was exactly as predicted. Nearly 600 health parameters were monitored during the test and the initial data indicates normal performance. Second successful static test of solid booster S200 conducted at SDSC, SHAR on September 4, 2011.^[11]

L-110 Static test

Indian Space Research Organisation conducted the static test of its liquid core stage (L110) of GSLV Mk III launch vehicle, for 150 seconds at its Liquid Propulsion Systems Centre (LPSC) test facility at Mahendragiri, Tamil Nadu at 16:00 hrs on March 5, 2010.While the test was originally targeted for 200 seconds it was stopped at 150 seconds since a deviation in one of the parameters was observed. Then on 8 September the same year ISRO successfully conducted the second static testing of L110 for 200 seconds .^[9]^[12] Nearly 500 health parameters were monitored during the test and the initial data acquired indicated its normal performance.^[9]
