Next Generation Launch Vehicle
The Next Generation Launch Vehicle (NGLV) is a family of three-stage partially reusable medium to super heavy-lift launch vehicle, currently under development by ISRO. The family of these vehicles are designed to replace currently operational systems like the PSLV and GSLV. Previously referred to as Unified Launch Vehicle (ULV), the project is now being called as Project Soorya.
This family of three launchers were previously being designed for replacing the different core propulsion modules of PSLV, GSLV, and LVM3 respectively with a common semi-cryogenic engine and hence it was named as ULV. The initial proposals were planned to be expendable. But the new (Oct 2022) proposals under the name of NGLV suggests launchers having partial reusability.
Dr S. Sivakumar is the program director for ISRO's Space Transportation System and the projector director for NGLV at the Vikram Sarabhai Space Centre (VSSC). In an interview, the former Chairman of ISRO S. Somanath stated that after the integration of the NGLV, all other launch vehicles will be retired, except the LVM3 and the SSLV.The development of the NGLV is projected to be 8 years from December 2024.I
The NGLV launch system has been in development by ISRO since the early 2010s and has gone through various design changes over time. As ISRO's launch vehicles were ageing, the need for a new generation of launchers with interchangeable modular parts was realised. There have been several design changes since the first proposal.
More than a decade after starting the Cryogenic Upper Stage Project in 1994, ISRO began developing a new semi-cryogenic engine that would be used on its next generation of vehicles of Unified Launch Vehicle (renamed to NGLV), Reusable Launch Vehicle (RLV) and a heavy-lift launcher for future inter-planetary missions. On 22 December 2008, the government approved the development of semi-cryogenic engine technology at an estimated cost of ₹1,798 crore (US$213 million), with a foreign exchange component of ₹588 crore (US$70 million), for the completion of the project by 2014, the engine was then named SE-2000 (now called the SE-2000).
In May 2013, the configurations of the launchers were revealed for the first time. They had a common core and upper stage, with four different booster sizes. 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 (now called the SE-2000) 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.
The four booster options were:
A potential heavy-lift variant (HLV) of the ULV, in theory was capable of placing up to 10 ton class of spacecraft into Geosynchronous Transfer Orbit. It was planned to include:
