HAL delivers biggest ever cryogenic propellant tank to ISRO
Hindustan Aeronautics Limited has delivered the biggest cryogenic propellant tank ever fabricated by the company to the Indian Space Research Organisation ahead of its contractual schedule.
The C32-LH2 tank is a developmental cryogenic propellant tank of aluminium alloy designed for improving the payload capability of the GSLV MK-III launching vehicle. The four-meter diametric tank is eight meters in length and can take on 5,755 kg of propellant in the 89 cubic meter space.
HAL said the total length of weld carried out in the tank was 115 meters at different stages to the quality requirement of 100% tests on radiography. Dye penetrant and leak-proof tests were carried out.
The propellant tank was handed over by M S Velpari, Director (Operations) of HAL to Dr V Narayanan, Director (LPSC) of ISRO recently.
