The GSLV Mk III , also called LVM3 or "Baahubali", is a heavy Indian launcher . Despite the same name, the Mark III is a completely different rocket from the Geosynchronous Satellite Launch Vehicle Mark I / II.

history

The new development of the GSLV Mark III based on the findings of the GSLV Mark II was decided in 2007. The cost should be around $ 520 million. The year 2008 was initially targeted as the first flight, but it has been postponed further and further. The first test of the first stage solid fuel booster took place on January 24, 2010 at the Satish Dhawan Space Center (SDSC), Sriharikota. The first launch date of the complete rocket was then set for early summer 2014 in 2013, but was postponed again by two months. In the meantime the name has been changed to LVM3. The first flight of the rocket then took place on December 18, during which a non-functional upper stage dummy was carried and so only the Crew Module Atmospheric Re-entry Experiment (CARE) serving as a payload was tested on the suborbital flight . The next launch of the LVM3 took place on June 5, 2017 and put the communications satellite GSAT-19 into orbit. There are plans to further develop the rocket in the future. This should be equipped with four boosters and a stronger core level.

technology

The three-stage rocket consists of two S200 solid rockets (boosters) serving as the first stage, an L110 core stage with two Vikas liquid rocket engines and the cryogenic upper stage C25 with a liquid rocket engine that uses liquid oxygen and hydrogen. The rocket has a launch mass of 630 tons and can put about 8 tons in low-Earth orbit at an altitude of 600 kilometers and about 4 tons on a geotransfer orbit. On the first flight it was a bundle rocket, in which the S200 solid propulsion units on the ground and the core stage were only ignited during the flight, before the S200 was disconnected.
