Polar Satellite Launch Vehicle

• Polar Satellite Launch Vehicle - Wikipedia, the free encyclopedia

  • The PSLV has four stages using solid and liquid propulsion systems alternately
  • The first stage is one of the largest solid-fuel rocket boosters in the world and carries 138 tonnes of Hydroxyl-terminated polybutadiene (HTPB) bound propellant with a diameter of 2.8 m. The motor case is made of maraging steel.
  • The second stage employs the Vikas engine and carries 41.5 tonnes (40 tonnes till C-5 mission) of liquid propellant – Unsymmetrical Di-Methyl Hydrazine (UDMH) as fuel and Nitrogen tetroxide (N2O4) as oxidize
  • The third stage uses 7 tonnes of HTPB-based solid propellant and produces a maximum thrust of 324 kN
  • The fourth and the terminal stage of PSLV has a twin engine configuration using liquid propellant
  • (Mono-Methyl Hydrazine as fuel + Mixed Oxides of Nitrogen as oxidiser)
