ISRO targets 2027 launch for LVM3 semi-cryogenic stage
▪ ISRO is aiming for a 2027 launch for its first LVM3 launch vehicle equipped with a semi-cryogenic propulsion stage.
About LVM3 (formerly GSLV Mk III)
▪ ISRO’s most powerful three-stage rocket.
▪ First experimental flight in December 2014.
▪ Current payload capacity: 4200 kg to GTO (Geosynchronous Transfer Orbit).
▪ The semi-cryogenic stage is designed to enhance payload capability while keeping costs down.
▪ Replaces L110 core stage (liquid propellant) with a semi-cryogenic stage.
▪ Semi-cryogenic engine as a “very complex one” that uses special materials to withstand high
temperatures and oxidiser-rich combustion.
▪ Whereas the liquid-fuelled Vikas engine gives a nominal thrust of 80 tonnes, the SE2000 semicryogenic engine is designed to supply 200 tonnes.
