Dr. '''V. N. Krishnamurthy''' (born 12 January 1937) is the former Dy. Director of [[Vssc|VSSC]] and Honorable Director of [[Isro|ISRO]]-[[University of Pune|UoP]] Interaction cell. He obtained his M.Sc. from [[Madras University]] and Ph.D. from [[Iisc|Indian Institute of Science]], [[Bangalore]] in 1967. He joined [[Vssc|Vikram Sarabhai Space Centre]], ([[Isro|Indian Space Research Organization]]) in February 1968 as chief of analytical facility. He became head of the Propellant Engineering Division in 1976, Group Director Propellants Group in 1986, and Deputy Director in 1989 before retiring in February 1997. After retiring, he became the Honorary Director of DRDO-ISRO-UoP Cells, which coordinates the activities undertaken for ISRO and DRDO at University of Pune. His tenure was over in August 2004 and after that he worked as an editor for two different encyclopaedias. Now he spends his time writing books and doing special guest lectures at universities and colleges in India.

==Research==
His main interests are in solid propellants for launch vehicles and sounding rockets, polymers and materials indigenisation. He was responsible for the development of propellants based on HEF20, ISRO polyol, PBAN, CTPB and [[HTPB]] for launch vehicles. He indigenised and scaled up all the polymers used as binders in launch vehicles. His important contributions are development of HTPB based propellants currently used in [[PSLV|Polar Satellite Launch Vehicle]] and [[GSLV|Geostationary Launch Vehicle]] stages, igniters and auxiliary rocket motors.

He established facilities for the synthesis and scale up of polymers and propellants used in launch vehicles and satellite systems for [[India]]. He planned, designed and set up the ammonium perchlorate experimental plant (APEP) at Alwaye and polymer complex at Veli Trivandrum. He planned, established and commissioned a pilot plant at [[Ordnance Factory Itarsi]] as a step towards indigenisation of equipments used in double base propellants.

He has published more than 150 papers in national and international journals and presented more than 150 papers in national and international conferences.<ref>{{cite web|url=http://pubs.acs.org/cgi-bin/article.cgi/cgdefu/2008/8/i03/html/cg070464+.html|title=Role of Poly(vinyl alcohol) in the Crystal Growth of Ammonium Perchlorate|publisher=}}</ref><ref>{{cite journal | doi=10.1016/j.jhazmat.2010.04.073 | pmid=20462689 | volume=180 | issue=1–3 | title=Use of potassium ferrocyanide as habit modifier in the size reduction and phase modification of ammonium nitrate crystals in slurries | journal=Journal of Hazardous Materials | pages=583–589| year=2010 | last1=Vargeese | first1=Anuj A. | last2=Joshi | first2=Satyawati S. | last3=Krishnamurthy | first3=V.N. }}</ref><ref>{{cite journal | doi=10.1016/j.tca.2011.07.009 | volume=524 | issue=1–2 | title=Thermal stability of habit modified ammonium nitrate: Insights from isoconversional kinetic analysis | journal=Thermochimica Acta | pages=165–169| year=2011 | last1=Vargeese | first1=Anuj A. | last2=Muralidharan | first2=Krishnamurthi | last3=Krishnamurthy | first3=V.N. }}</ref>

==Awards==
He was given the NRDC award in 1994 for contributions to propellants and for the development of a new technology of making big solid propellant grains.<ref>{{Cite web |url=http://www.nrdcindia.com/invention_award.htm |title=Archived copy |access-date=22 August 2012 |archive-url=https://web.archive.org/web/20120425052056/http://www.nrdcindia.com/invention_award.htm |archive-date=25 April 2012 |url-status=dead |df=dmy-all }}</ref> He was presented with the FIE foundation award at [[Ichalkaranji]] for overall contributions to polymers and propellants development for space programmes. He was awarded the Materials Research Society (MRSI) award for contributions to materials research for space programmes in 1997.
