Computational Design and Optimization of Supersonic Intakes

Dr. Jatinder Pal Singh Sandhu is a senior R&D engineer at Yanxiki Tech., Pune, India. He has nearly a decade of experience in numerical computation and analysis of compressible high-speed flow. His expertise includes passive flow control of shock-wave boundary layer interaction, high-speed intakes, turbulence and transition modeling, and computational flow solver development. He was awarded a PhD by the Indian Institute of Technology Madras, India, for his work on laminar-to-turbulence transition modeling.Dr. Ik Soo Park, an expert in propulsion and control technology for guided missiles and aircraft, currently works at the Agency for Defense Development of the Republic of Korea. With 30 years of experience in the field, he has conducted practical-oriented research, including system design control algorithms for supersonic inlet, combustion instability, rocket thrust vector, and DACS. His invaluable contributions to the development of rockets and air intake propulsion engines have led to the publication of ground-breaking research results, earning him multiple Best Paper awards. Currently residing in Daejeon, South Korea, Dr. Park actively serves as the academic director of the Korean Society of Propulsion Engineering and the Korea Aerospace System Engineering Society. He engages in academic activities through AIAA, IEEE, KSAS, and KSPE. Moreover, Dr. Park maintains regular exchanges with scholars from over 20 renowned research institutes worldwide, conducting international joint research and fostering continuous collaboration in related fields.Dr Narayan Ananthkrishnan is an Independent Consultant presently based out of Mumbai (India) with nearly 30 years experience in academia and industry in multi-disciplinary research and development across a wide spectrum from Flight Dynamics & Control to Airplane Aerodynamics to Combustion Systems. Over the past decade, he has largely worked with businesses in the Mumbai/Pune area and Bangalore in India, and in Seoul and Daejeon, South Korea, and with a few select academic institutes. His recent work has focused on the broad area of Aerospace Systems Design & Integration with emphasis on Multidisciplinary Optimization and Air-breathing Propulsion Systems. He has previously served on the faculty of Aerospace Engineering at the Indian Institute of Technology, IIT Bombay at Mumbai, India, and as a Visiting Faculty Member at the California Institute of Technology at Pasadena, CA, USA. He received the “Excellence in Teaching” award at IIT Bombay in the year 2000. He has authored two textbooks (with NK Sinha), Elementary Flight Dynamics with an Introduction to Bifurcation and Continuation Methods, published by CRC Press, Taylor & Francis (2014, 2nd ed. in 2022, Chinese ed. in 2022) and Advanced Flight Dynamics with Elements of Flight Control, also published by CRC Press, Taylor & Francis (2017). He has also written an e-book on Airplane Systems, Design, and Operations. He received his education in Aerospace Engineering at the Indian Institutes of Technology, majoring in Flight Mechanics & Control, Aerodynamics, Aircraft Design, and Nonlinear Systems. He is an Associate Fellow at American Institute of Aeronautics & Astronautics (AIAA) and has served a term as a member of the AIAA Atmospheric Flight Mechanics Technical Committee.
