Abstract

The National Trisonic Aerodynamics Facility (NTAF) has proven to be the workhorse for experimental aerodynamic data generation for numerous projects in the country. Since its inception, extremely valuable data has been provided by this facility to its primary stakeholders, viz., VSSC, ADA and DRDO. As of today, the data generated from this facility alone represents a vast body of knowledge. More recently, there have been other facilities in the country which have also made significant contributions to this body of knowledge. More recently, there have been other facilities in the country which have also made significant contributions to this body of knowledge. The National Wind Tunnel Facility (NWTF) and the wind tunnels at IISc are typical examples. Computational Fluid Dynamics (CFD) groups started taking roots in the country by around 1970's and established themselves over the last three decades. Some of the important CFD groups include those active in NAL, ADA, DRDO, IISc, VSSC, IIT Kanpur etc. Over the years, CFD codes have been developed by these groups and applied to several national projects. Such exercise has strengthened the value of these codes. This activity has also resulted in adding to the aerodynamic data. Flight test data adds another dimension that makes this body of knowledge far richer. Thanks to national aircraft projects, there is now a good amount of this data available. The flow past tall structures such as chimneys, multi-storeyed buildings, TV and Communication towers, automobiles, high speed trains and bridges, etc, are being studied in various low-speed wind tunnels in India in aerospace as well as civil engineering disciplines. There is also a renewed interest in indigenous development of wind turbines, requiring generation of wind tunnel data as well as field data. Public funded agencies such as AR amp; DB, DST, UGC, etc., spend considerable amount of funds towards growth of knowledge in aerospace sciences and technologies. The outcome of these grants could be in the form of national and international journal publications, reports, patents, and so on. Availability of this knowledge in a national database not only helps in dissemination o knowledge, but also enables the managers of funding agencies towards efficient monitoring and management of projects through e-governance.
