ETHIRAJAN RATHAKRISHNAN, Ph.D., is Professor of Aerospace Engineering at the Indian Institute of Technology Kanpur. He is well-known internationally for his research in the area of high-speed jets. The limit for the passive control of jets, called Rathakrishnan Limit, is the contribution to the field of jet research. The concept of breathing blunt nose (BBN), which reduces the positive pressure at the nose and increases the positive pressure at the base simultaneously, is his contribution to drag reduction at hypersonic speeds. Recently he received a ‘Lifetime Achievement Award’ from International Sustainable Aviation and Energy Research Society (SARES) for his novel scientific contributions to the area of Sustainable Aviation and Energy. He has published a large number of research articles in many reputed international journals. He is a Fellow of many professional societies, including the Royal Aeronautical Society.
Professor Rathakrishnan serves as the Editor-in-Chief of the International Review of Aerospace Engineering (IREASE) and International Review of Mechanical Engineering (IREME) journals. He has authored eleven books including Fundamentals of Engineering Thermodynamics (2nd ed), Helicopter Aerodynamics and Gas Dynamics (7th ed), published by PHI Learning, Delhi.
