Defence aerospace major Hindustan Aeronautics Ltd (HAL) on Thursday delivered its heaviest semi-cryogenic propellant tank (SC120- LOX) ever fabricated to the Indian Space Research Organization (ISRO).
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.
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.
The propellant tank was handed over by MK Mishra, General Manager, Aerospace Division, HAL, to TKB Kumaresh Babu, General Manager (LHWC), Head of the resident team of Liquid Propulsion Systems Centre (LPSC), ISRO, in the presence of P Srinivasa Rao, Group Director (SR)-LPSC, at a function held in HAL.
HAL has mastered the skills and technologies required for fabricating welded propellant tanks.
