Dr. G K Suryanarayana

Professor

Dr. Suryanarayana obtained his BTech degree in Aeronautical Engineering from the Madras Institute of Technology, Master’s and Doctoral degrees in Aeronautical Engineering from the Indian Institute of Science, Bangalore. After short stint of work as Engineer in Air India, Mumbai he joined the National Aerospace Laboratories, Bangalore as a Scientist in Research and Development in the area of experimental aerodynamics. He has made significant contributions in the development of launch vehicles of ISRO and missiles developed by DRDO laboratories, such as ASLV, PSLV, GSLV, Re-Useable Launch Vehicle, Space-capsule Recovery Module, Scramjet Technology Demonstrator, BrahMos, Nirbhay, LCA, etc. He introduced several new test techniques and test facilities for high-speed wind tunnel testing of models related to national aerospace programmes, such as the Variable Mach number Flexible Nozzle, Passive and Active Ejector systems for testing of air-intake models, Systems for dynamic stability testing for free and forced oscillations, Unsteady pressure measurements, Supersonic air intakes, High-speed Schlieren, etc. He has authored several publications in the AIAA Conferences, Journal of Spacecraft and Rockets, Experiments in Fluids (Springer), The Aeronautical Journal (UK) and Journal of Aerospace Sciences and Technologies (India) and has received international citations from well-known journals. He has also authored a book on reduction on aerodynamic drag of bluff bodies and has a patent on lift generation using vortices. He is currently guiding Doctoral students at IISc and IIT Madras. He has served as Chairman and Member of several Expert Review Committees related to national aerospace programmes and is on the Editorial Board of the Journal of Aerospace Sciences and Technologies, Aeronautical Society of India and is also a reviewer in some of the well known journals. His research interests include reduction of aerodynamic drag, innovations in active and passive flow control, unsteady aerodynamics, air-intake aerodynamics, transonic flows. He is a Research Ambassador of the German Academic Exchange Service, New Delhi. He is also interested in infusing experimental research related to national aerospace programmes into the academic sector. His PhD Students cum Scientists in CSIR-National Aerospace Laboratories, Bangalore have won appreciations for Outstanding Research in the area of Experimental Aerodynamics. He has been working in multi-disciplinary areas of research and has filed Indian Patents on (i) Improved heat transfer and (ii) Nano-Sir Vehicle for low altitude and low-speed flying. In the area of Climate Change, he has developed and transferred technology to a Bangalore-based Start-Up Company for Direct Absorption of Carbon Dioxide from the atmosphere and is planning to build a prototype for commercial production.
