The Indian Institute of Science (IISc) will inaugurate the upgraded Open Circuit Wind Tunnel (OCWT) on January 12. This tunnel is the oldest in India, started in the 1950s and completed in 1959 under Prof. Satish Dhawan's leadership. It was first opened by Maharaja Jaya Chamaraja Wadiyar of Mysore. The OCWT remains the largest wind tunnel facility in India. Over 66 years, it has helped many aerospace and other national projects with over 370 test campaigns. In 2025, the OCWT received a major upgrade supported by TVS and IISc, including a modern fan-motor drive system. This upgrade raises the maximum test speed from 45 meters per second to 70 meters per second, offering better speed control and more automation. The OCWT complex also has a top-tier High-Performance Computing (HPC) cluster. Launched in 2018 with 224 CPU cores, it was expanded in December 2025 to include 1,280 more CPU cores, supported by RWRDC-HAL. These use the latest AMD EPYC processors and will mainly run Computational Fluid Dynamics (CFD) simulations for HAL projects. The department also uses PARAM-Pravega at IISc's Supercomputer Education and Research Centre (SERC) for additional computing needs.
