The Hindustan Aeronautics Limited (HAL) has delivered the biggest cryogenic propellant tank (C32 LH2) ever formed by the company to the Indian Space Research Organisation (Isro) much ahead of the contractual schedule at a program held in Bengaluru, Karnataka, recently.
The C32-LH2 tank is a developmental cryogenic propellant tank of aluminium alloy designed for improving the payload capability of GSLV MK-III launching vehicle, HAL said in a press release.
The propellant tank was handed over by MS Velpari, Director (Operations), HAL to Dr V Narayanan, Director (LPSC), Isro in the presence of S Somanath, Director (VSSC) with other senior scientists from ISRO, participating in virtual mode and other senior officials of HAL.
Somanath acknowledged HAL's contributions to India's space program as one of the valuable partners of the Isro in its journey.
While appreciating HAL's capability in absorbing any technological advancements and developments in productionising any types of space hardware and structures for the space launch vehicle, he highlighted HAL's role in developing eco-system by sharing the knowledge among private players towards strengthening the supply chain.
While receiving the hardware, Dr V Narayanan thanked the entire workforce of HAL for successful production of the developmental project.
The four meter diametric tank is of 8 meter length to load 5755 kg propellant in the 89 cubic meter volume. Total length of weld carried out in the tank was 115 meter at different stages to the quality requirement of 100 per cent tests on radiography, Die penetrant check and Leak proof.
The HAL has mastered the skills and technologies required for fabricating welded propellant tank of Aluminium ally to such stringent quality requirement.
The company, as a strategic reliable partner, has been associating with the Isro for the prestigious space programs since last five decades. HAL has supplied critical structures, tankages, 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, for which setting up of necessary infrastructure and facilities is nearing completion.
The HAL has also supported the Isro right from the developmental phase of Crew Atmospheric Re-entry Experiment, PAD Abort test for Crew Escape for Human Space Mission and is currently building hardware for full-fledged launch vehicle GSLV Mk-III for Gaganyaan program.
