Roddam Narasimha FRS (20 July 1933 – 14 December 2020) was an Indian aerospace scientist and fluid dynamicist. He was a professor of Aerospace Engineering at the Indian Institute of Science (1962–1999), director of the National Aerospace Laboratories (1984–1993) and the chairman of the Engineering Mechanics Unit at Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR, 2000–2014).[6] He was the DST Year-of-Science Chair Professor at JNCASR and concurrently held the Pratt & Whitney Chair in Science and Engineering at the University of Hyderabad. Narasimha was awarded the Padma Vibhushan, India's second-highest civilian award, in 2013.[7] for his contributions to advance India's aerospace technology.
Early life
Narasimha was born on 20 July 1933. He was born in a Kannada family tracing its origins to

Career
Narasimha started his research career at
He returned to India in 1962, and joined the
He was the ISRO K. R. Ramanathan distinguished professor at the Indian Institute of Science (1994–1999), Director of the National Aerospace Laboratories (1984–1993), Director of the National Institute of Advanced Studies (1997–2004) and the Chairman of the Engineering Mechanics Unit at Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR), Bangalore (2000–2014).[14] He was the DST Year-of-Science Chair Professor at JNCASR and also held the Pratt & Whitney Chair in Science and Engineering at the University of Hyderabad.[12][15] He was also a visiting member of the faculty at international universities including the University of Brussels, Caltech, University of Cambridge, Langley Research Center, University of Strathclyde and University of Adelaide.[12] He served former Prime Minister Rajiv Gandhi's scientific advisory council.[12]
During his time at the National Aerospace Laboratories, Narasimha led the research initiative into parallel computing as a means to solve fluid dynamics problems.[12][16] His efforts lead to first parallel computer in India and development of a code for weather prediction of tropical regions. He was also a contributing member to the team that designed the light combat aircraft.[17]
Over the course of his six decade long academic career he has made significant contributions to fundamental and applied fluid dynamics. At the Indian Institute of Science, his research included the ‘bursting’ phenomenon in a turbulent boundary layer,[18] non-linear vibration of an elastic string,[19] equilibrium and relaxation in turbulent wakes,[20] relaminarization,[21] hydrodynamic instability,[22] wall jets[23] and the study of clouds[24][25] as volumetrically heated jets. At the Engineering Mechanics Unit of the Jawaharlal Nehru Centre for Advanced Scientific Research, Narasimha continued his research on fluid dynamics of clouds via laboratory experiments[26] as well as numerical simulations.[27] He also studied gas turbine blades,[28] turbulent free shear layers[29] and proposed a novel wing design for turboprop aircraft.[30]
He was the longest-serving member of the Indian Space Commission, a policy-making body for space exploration in India.[12] He resigned from this position in February 2012, in protest at the blacklisting of three former ISRO technocrats including G. Madhavan Nair, former ISRO chairman, for their perceived role in a controversial agreement between ISRO's commercial entity Antrix and Devas Multimedia in 2005.[31][32]
