<p>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.</p>.<p>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. </p>.<p>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. </p>.<p>The propellant tank was handed over by M S Velpari, Director (Operations) of HAL to Dr V Narayanan, Director (LPSC) of ISRO recently.</p>.<p>HAL has previously supplied critical structures, tankages and satellite structures for the PSLV, GSLV-MkII and GSLV-MkIII launch vehicle. Various new projects like PS2/GS2 integration, semi-cryo structure fabrication and manufacture of cryo and semi-cryo engines are being taken up at HAL. The firm is currently also building hardware for full-fledged launch vehicle GSLV Mk-III for the Gaganyaan programme.</p>
