Features of GSLV Mark-III

Biggest launch vehicle so far.

By this ISRO’s human spaceflight programme aims to send two astronauts into LEO and bring them back safely.

It is also significant from the perspective of ISRO’s own cryogenic engine.

Stage-1: Solid Boosters

These boosters burn for 130sec and produce a peak thrust of about 5150 kilo newton each.

It has a large nozzle which helps in orientation.

Stage 2: Liquid motor The core stage designated L110, produce 700 Kilo newton uses regenerative cooling.

The core stage designated is a 4 meter diameter carrying 110 tonnes of UDMH and N2O4.

It is the first Indian liquid-engine cluster design and uses two improved Vikas engines.

Stage 3: Cryogenic stage

It is designated as C25, will be powered by the Indian developed CE-20 engine burning LOX and LH2 producing 186 kilo newtons.

CARE separated from the passive C25 cryogenic upper stage of GSLV Mk-III 330.8 seconds after lift-off and began its guided descent for atmospheric re-entry.

After the successful re-entry phase, CARE module’s parachutes opened, following which it gently landed over Andaman Sea about 1600 km from Sriharikota.

The first orbital flight is planned to take place in 2016.

The first flight with a crew on board would take place after 2020

The successful launch of ISRO’s GSLV MARK-III make India fully self dependent in launching heavier communication satellites of INSAT-4 class, which weigh 4500-5000Kg.
