Unified Launch Vehicle


The Unified Launch Vehicle is a development project by the Indian Space Research Organisation 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. 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. As SCE-200 will only fly after the successful completion of the Gaganyaan program, the launcher will not fly before 2022.

Design

As of May 2013, based on ISRO data, the design comprised a common core and upper stage, with four different booster sizes. 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. The core, known as the SC160, would have of Kerosene / LOX propellant and be powered by a single SCE-200 rocket engine. The upper stage, known as the C30 would have of LH2 / LOX propellant and be powered by a single CE-20 engine.
The four booster options are:

A potential heavy-lift variant of the unified launcher capable of placing up to 10 ton class of spacecrafts into Geosynchronous Transfer Orbit would include:
