Must read

New Delhi/Bengaluru: The heaviest semi-cryogenic propellant tank (SC120- LOX) ever fabricated by Hindustan Aeronautics Limited (HAL) has been delivered to the Indian Space Research Organization (ISRO). "The Propellant Tank has been handed over by HAL's General Manager (Aerospace Division) MK Mishra to TKB Kumaresh Babu, GM (LHWC), Head of the resident team of LPSC of ISRO in the presence of P Srinivasa Rao, GD (SR) – LPSC at a function held in HAL", the defence PSU said in an official statement.

"The semi cryo-liquid oxygen (LOX) tank – the first developmental welded hardware is a part of the SC120 stage intended for payload enhancement by replacing the L110 stage in the existing Mk-III launch vehicle", the statement added. 

Last year, HAL had delivered the biggest ever cryogenic Liquid Hydrogen tank (C32-LH2) which is four meters in diameter and eight meters in length, much ahead of the contractual schedule.

HAL has mastered the skills and technologies required for fabricating welded propellant tanks. To date, its Aerospace Division has delivered 244 propellant tanks and 95 water tanks to ISRO for the space programmes of PSLV, GSLV Mk-II and GSLV Mk-III of diameter 2.1, 2.8 and 4 meters where the length of the tank varies from 2.5 meters to 8.0 meters.


As a strategic reliable partner, HAL has been associating with ISRO for India’s prestigious space programs for the last five decades. HAL has delivered critical structures, tankages, satellite structures for the PSLV, GSLV-Mk II and GSLV-Mk III launch vehicles.  Various new projects like PS2/GS2 integration, Semi-cryo structure fabrication and manufacturing of cryo and semi cryo engines are being taken up at HAL, for which installation and commissioning of unique infrastructures are nearing completion.
