Narayanan joined ISRO in 1966. In the early 1970s, Narayanan predicted the need for liquid-fueled engines in ISRO’s future civilian space programmes. He designed the first thrust liquid propellant motors of around 600kg and introduced the liquid fuel rocket technology in India while A.P.J. Abdul Kalam and his team worked on solid motors. Narayanan’s project was greatly supported by the then ISRO chairman Satish Dhawan and U. R. Rao. He was in charge of the cryogenics division, which is the production of materials at low temperature.

  • In 1992, India made an agreement with Russia for 235 Crore to transfer technology in the development of cryogenic fuels. However, the deal was cancelled due to pressure from the US and France, who intended to offer Russia the same technology for around 950 crore and 650 respectively. Subsequently, India made a fresh agreement with Russia to manufacture four cryogenic engines by a global tender without the transfer of technology. But the deal was also cancelled due to the false espionage scandal that surfaced in 1994.
  • In 1994, Narayanan along with his fellow scientist, D Sasikumaran, and two Maldivian women named Mariam Rasheeda and Fauzia Hassan was falsely charged for leaking vital defence secrets which included confidential pieces of information related to flight test data. The other accused persons were ISRO’s contractor S.K. Sharma and a Russian space agency official K. Chandrasekhar.
