ULV (Unified LV) |
Indian Space Research Organisation
ULV 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 (L-160) uses Kerosene/LOX. The used conceptual engine RD-810* from Yuzhnoye (Ukraine) with 200 t of thrust, is in development and should be ready in some years. The RD-810 engine is an licensed RD-120MN engine of Energomash. The CE-20 engine from the GSLV MkIII is used for the larger L-30 cryogenic upper stage. Planned is a more powerful engine CE-60 with 600 kN thrust. The smallest version
of the ULV uses six S-13 booster and has a launch mass of 274 t. The payload
is 1.5 t for GTO and 4.5 t for LEO.
HLV
This
HLV concept (one SCE-200 engine and a cryogenic CE-60 engine) is obviously no
longer favored. In a new concept, five SCE-200 engines are planned
(see
Versions, Propulsion).
