ANSWER: GSLV Mk III
 
ISRO launches GSLV Mk III cryogenic engineISRO has successfully tested its indigenously developed cryogenic engine.

This is a major step forward for its landmark 'GSLV Mk III' rocket.

The rocket is scheduled for launch within the first quarter this year.

Cryogenic engines are used in the upper stage of a rocket launch.

They provide the maximum thrust to a launcher vehicle.

The cryogenic upper stage, designated as C25, was tested on January 25.

It was tested for 50 seconds at ISRO Propulsion Complex (IPRC) at Mahendragiri in Tamil Nadu.

This was the first test in a series of two tests. The next one was planned for a flight duration of 640 seconds.

The 50 second test is a significant milestone in the development of indigenous cryogenic propulsion technology.

Successful hot test of the stage in the first attempt itself demonstrates the agency's ability to work in new areas like cryogenic technology.

The development of C25 cryogenic stage began with the approval of GSLV MkIII.

This is the next generation launch vehicle of ISRO, capable of launching 4 ton class spacecraft in Geosynchronous Transfer Orbit (GTO).

The vehicle consists of two solid strap-on motors, one earth storable liquid core stage and the cryogenic upper stage.

The C25 stage is the most powerful upper stage developed by ISRO.

It uses Liquid Oxygen and Liquid Hydrogen propellant combination.

The stage carries 27.8 tons of propellants loaded in two independent tanks.

The first flight stage for 'GSLV MkIII-D1' mission is in an advanced stage of realisation.

It is scheduled to launch GSAT-19 during first quarter of 2017.

The flight engine has been successfully tested in the High Altitude Test facility.

It is integrated with the flight stage, ISRO said.

The C25 stage was conceptualised, designed and realised by Liquid Propulsion Systems Centre (LPSC), ISRO's lead Centre for Propulsion.

There is support from various System Development Agencies from other three Centres of ISRO -
  • Vikram Sarabhai Space Centre (VSSC),
  • ISRO Propulsion Complex (IPRC) and
  • Sathish Dhawan Space Centre (SDSC).
GSLV MkIII vehicle consists of two solid strap-on motors, one earth storable liquid core stage and the cryogenic upper stage.

The C25 stage is most powerful upper stage developed by ISRO.

It uses Liquid Oxygen and Liquid Hydrogen propellant combination.

This stage carries 27.8 tons of propellants loaded in two independent tanks. Note:

What is a Cryogenic Engine C-25?
  • Cryogenic engines are used in the upper stage of the rocket launch.
  • They provide the maximum thrust to the launcher vehicle.
  • Development of a cryogenic stage has unique design challenges liquid Oxygen stored at -195 deg C and as liquid Hydrogen is stored at -253 deg C in its tanks.
  • To store these cryogenic fluids, special multi-layer insulation is provided for the tanks and other structures.
  • The successful hot test of the stage in the first attempt itself demonstrates the ISRO’s ability to work in new areas like cryogenic technology.
  • The first flight stage for ‘GSLV MkIII-D1’ mission is in an advanced stage of realisation.
  • It is scheduled to launch GSAT-19 during first quarter of 2017.
