Payload fairing left|thumb|PSLV heat shield at HAL Aerospace Museum, Bengaluru Payload fairing of PSLV, also referred as its "Heatshield" consists of a conical upper section with spherical nose-cap, a cylindrical middle section and a lower boat-tail section. Weighing , it has 3.2 meter diameter and 8.3 meter height. It has Isogrid construction and is made out of 7075 aluminum alloy with a 3 mm thick steel nose-cap. The two halves of fairing are separated using a pyrotechnic device based jettisoning system consisting of horizontal and lateral separation mechanisms. To protect the spacecraft from damage due to excessive acoustic loads during launch, the heatshield interior is lined with acoustic blankets.
