Hindustan Aeronautics Ltd. (HAL) supplied the cryogenic fuel tanks and the cryo stage structures that formed part of the GSLV‐D5, which was successfully launched on Sunday, the public enterprise has said. HAL integrated and provided the four small ‘L40’ booster rockets strapped on to the first stage. L40 denotes the 40 tonnes of liquid fuel they carry. It also provided the basic structure of the communication satellite GSAT‐14, an assembly of composite and metallic honeycomb sandwich panels with a composite cylinder. HAL routinely supplies these pieces of hardware for the Indian Space Research Organisation’s launch vehicle as well as spacecraft programmes.
