Launch Vehicle Technology
-
In the field of launch vehicle technology, India has evolved a four-stage development programme. In the first stage SLV-3 (Satellite Launching Vehicle-3) was developed. Rohini satellite was launched with its help. In the second stage ASLV (Augmented Satellite Launch Vehicle) was developed. In the third stage PSLV (Polar Satellite Launch Vehicle) was developed in which liquid propellant was used for the first time along with solid propellants. In the fourth stage GSLV (Geo-stationary Launch Vehicle) was developed. Its second and fourth stage uses cryogenic engines. They use liquid hydrogen as fuel at -253° C and liquid oxygen at -183° C as oxidiser.
