HAL Delivers Crew Module Structural Assembly To ISRO


Hindustan Aeronautics Limited (HAL) delivered the first “Crew Module Structural Assembly” for the Indian Human Spaceflight Program to Vikram Sarabhai Space Centre (VSSC), Thiruvananthapuram of ISRO in Bangalore, recently. The first Crew Module will be further equipped with systems necessary for navigation, guidance, Environmental Control and Life Support System (ECLSS), Crew Escape System by ISRO for experimentation in the forthcoming maiden flight test of GSLV-MK3 launcher. Earlier also HAL has contributed in the India’s space programmes such as “ISRO’s Mars Mission” by providing Satellite Structure, Propellant Tankages and supplied thirteen types of riveted structural assemblies, seven types of welded propellant tankages which include the cryogenic liquid oxygen and liquid hydrogen tanks and cryogenic stage structures for GSLV D5.
 GSLV-MkIII is a three stage heavy lift launch vehicle, designed for launching four tonne class of communication satellites to Geosynchronous Transfer Orbit (GTO). It has three propulsion stages and is 42.4 m tall with a lift-off weight of 630 tonnes. Two identical large solid strap-on boosters (S200) with 200 tonnes of solid propellant are strapped on either side of the core stage (L110) with 110 tonnes of liquid propellant loading. The upper stage is the cryogenic stage (C25) with 27 tonnes propellant loading. Carbon Fibre Reinforced Polymer (CFRP) payload fairing measures 5 m in diameter which can accommodate a payload volume of 100 cu m. GSLV Mk3 will end India's reliance on European Ariane 5 launcher for heavy communication satellites launches weighing more than 2.5 tonnes.
