ULV (Unified Launch Vehicle)



India will develops a new series of SLV, which will replace both the PSLV and GSLV. The ULV (Unified Launch Vehicle) marks the renunciation of India for N2O4/UDMH as propellant for space launch vehicle systems.

The ULV is a future expendable launch vehicle concept on base the GSLV MkIII design. It is modular in shape, comprising semi-cryogenics as core stage, a cryogenics as upper stage and strap-ons of different magnitudes made of solid rockets. It can be S-200, S-138 usw., depending on the payload requirement.

The various configurations of the ULV have an identical first and upper stage. The first stage uses kerosene/LOX. The used engine RD-810 from Yuzhnoye (Ukraine) with 200 t of thrust, is in development and should be ready in four to six years. In the first time the CE-20 engine from the GSLV MkIII is used for the cryogenic upper stage of the ULV. Planned is a more powerful engine CE-60 with 600 kN thrust.

The smallest version of the ULV uses six S-12 booster and has a launch mass of 274 t. The payload is 1.5 t for GTO and 4.5 t for LEO.

The second version uses two S-60 booster and has a launch mass of 340 t. The payload is 3 t for the GTO or 10 t for LEO.

The third version uses two S-138 booster and has a launch mass of 560 t. The payload is 4.5 t for GTO and 12 t for LEO.

The most powerful variant is to use the S-200 booster of GSLV MkIII and has a launch mass of 700 t. The payload is 6 t for GTO and 15 t for LEO.

No timelines are given? Does anybody know ? 2030?
why havn't you read this line....

the nuclear propulsion interplanetary vehicle seem like a good idea, semi cryogenic core stage is definitely the next thing in to do list but still I think such a plan should be released after 5th Jan GSLV mkII launch.
