== Early life ==
Narasimha was born on 20 July 1933. He was born in a Kannada family tracing its origins to [[Roddam, Anantapur district|Roddam]], a village in the [[Anantapur district]] of [[Andhra Pradesh]].<ref name=":1">{{Cite web|title=Aakaasha Raaya – Bhāvanā|url=https://bhavana.org.in/roddam-narasimha/|access-date=15 December 2020|language=en-US|archive-date=15 December 2020|archive-url=https://web.archive.org/web/20201215030327/http://bhavana.org.in/roddam-narasimha/|url-status=live}}</ref> His father, R.L.

Narasimha completed his schooling at [[Acharya Pathasala Public School|Acharya Pathasala]] in the [[Gandhi Bazaar]] neighbourhood of Bangalore.<ref name=":1" /> He obtained his graduate degree in mechanical engineering from [[University of Visvesvaraya College of Engineering]] in Bangalore, which was affiliated with [[Mysore University]]. During this time he visited the [[Tata Institute]] (now known as the Indian Institute of Science), where the [[Supermarine Spitfire|Spitfire aircraft]] displayed in the aeronautical department caught his interest. After his graduation in 1953, while he was encouraged by his family members to accept a job with the [[Indian Railways]] or with [[Burmah Shell]], but he went on to join the [[Indian Institute of Science]] in Bangalore for his master's degree in engineering, which he completed in 1955.<ref>{{cite web|title=Caltech Aerospace (GALCIT)|url=http://www.galcit.caltech.edu/about/history#1941|access-date=14 April 2018|publisher=Galcit.caltech.edu|archive-date=14 November 2013|archive-url=https://web.archive.org/web/20131114064710/http://www.galcit.caltech.edu/about/history#1941|url-status=live}}</ref> During this time he worked with [[Satish Dhawan]], who later chaired the [[Indian Space Research Organisation]].

==Career==
Narasimha started his research career at [[California Institute of Technology|Caltech]], working on the problem of [[jet engine]] noise reduction. After the launch of the Russian [[Sputnik 1|''Sputnik'']] and the resulting interest in space programs, he shifted focus to [[rarefied]] gas and [[fluid dynamics]], working with [[Hans W. Liepmann]].<ref name=":2">{{Cite web|last=Sandhya Ramesh|date=15 December 2020|title=Aerospace scientist Roddam Narasimha, 'an authority on fluid dynamics', dies at 87|url=https://theprint.in/science/aerospace-scientist-roddam-narasimha-an-authority-on-fluid-dynamics-dies-at-87/567020/|access-date=16 December 2020|website=[[ThePrint]]|language=en-US|archive-date=15 December 2020|archive-url=https://web.archive.org/web/20201215093439/https://theprint.in/science/aerospace-scientist-roddam-narasimha-an-authority-on-fluid-dynamics-dies-at-87/567020/|url-status=live}}</ref> He continued this research at the [[NASA Jet Propulsion Laboratory]], where he went on to study aerodynamics and supersonic flows toward better understanding of the structure of shockwaves.
