Hints to Remember
Indian Space Research Organization (ISRO)
tested its indigenously developed cryogenic engine in a major step forward for its landmark ‘GSLV Mk III’ rocket
published on 27th
The Indian Space Research Organization (ISRO) has recently tested indigenously developed cryogenic engine for the upper stage ‘GSLV Mk III’ rocket.
The cryogenic upper stage, designated as C25, was tested for 50 seconds at ISRO Propulsion Complex (IPRC) at Mahendragiri in Tamil Nadu demonstrating all the stage operations. It was the first test in a series of two tests. The second test is planned for flight duration of 640 seconds.
1. Cryogenic engines are used in the upper stage of a rocket launch as they provide the maximum thrust to a launcher vehicle.
2. The development of C25 cryogenic stage started after approval of GSLV MkIII, ISRO’s next generation launch vehicle, capable of launching heavy four tonne class spacecraft in Geosynchronous Transfer Orbit (GTO).
3. C25 stage was conceptualized, designed and realized by Liquid Propulsion Systems Centre (LPSC) with support from Vikram Sarabhai Space Centre (VSSC), ISRO Propulsion Complex (IPRC) and Sathish Dhawan Space Centre (SDSC).
4. GSLV MkIII vehicle consists of two solid strap-on motors, one earth storable liquid core stage and the cryogenic upper stage.
5. 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.
