The Unified Launch Vehicle (ULV) is a development project by the Indian Space Research Organisation (ISRO) whose core objective is to design a modular architecture that could eventually replace the PSLV, GSLV Mk I/II and GSLV Mk III with a single family of launchers.[1] The design may include a heavy-lift variant dubbed HLV, consisting of the SC-160 stage and two solid rocket boosters, as well as a super heavy-lift variant called SHLV with a cluster stage of five SCE-200 engines .[1][12] As SCE-200 will only fly after the successful completion of the Gaganyaan program, the launcher will not fly before 2022.[4]

Design

As of May 2013, based on ISRO data, the design comprised a common core and upper stage, with four different booster sizes.[13] All four versions of the boosters are solid motors, with at least three versions reusing current motors from the PSLV, GSLV Mk I/II and LVM3.[5] The core, known as the SC160 (Semi-Cryogenic stage with 160 tonnes of propellant, in the ISRO nomenclature), would have 160,000 kg (350,000 lb) of Kerosene / LOX propellant and be powered by a single SCE-200 rocket engine. The upper stage, known as the C30 (Cryogenic stage with 30 tonnes of propellant) would have 30,000 kg (66,000 lb) of LH2 / LOX propellant and be powered by a single CE-20 engine.[1][12]

The four booster options are:

  • 6 × S-13, slightly larger than the S-12 on PSLV, to burn longer;
  • 2 × S-60, which appears to be a new solid motor development;
  • 2 × S-139, which is the first stage of PSLV and GSLV Mk I/II;
  • 2 × S-200, like on the LVM3.


Heavy Lift Launch Vehicle (HLV-Variant):-

A potential heavy-lift variant (HLV) of the unified launcher capable of placing up to 10 ton class of spacecraft into Geosynchronous Transfer Orbit would include:[1][14][12]

  • A larger dual S-250 solid strap-on boosters as compared to the S-200 boosters used in LVM3;
  • A L-400 semi-cryogenic core stage, with 400 tonnes of propellant, using a cluster of five SCE-200 engines;
  • A L-27 cryogenic third stage, with 27 tonnes of propellant, using CE-20 engine.
