Sponsored Research Projects

Lifetime experiences..

Cited above are the four sponsored research projects that drove a good part of my career. Cumulatively spanning over ten years, these projects were lifetime experiences adding to my learning aside from thinking. Do read on for more details..

VSSC (ISRO)

Project #1, awarded by VSSC, was on development of GENSOLV, for GENetic Structural Optimization of Launch Vehicles. VSSC (Govt of India, Dept. of Space) is the largest center of ISRO, involved in development of launch vehicles. VSSC's family primarily is two- member strong:  PSLV (near earth, polar sun- synchronous orbit) and GSLV (geo- synchronous orbit), both of which are now commercial.

CVRDE (DRDO)

Projects #2, #3 and #4 were sponsored by CVRDE (DRDO). CVRDE (Combat Vehicles Research and Development Establishment) is a premier organization of the DRDO (Govt of India, Min of Defence). CVRDE's mission is centered around development of battle tanks, across all disciplines from armament and armor through electronics and intelligence.


I'm also grateful to DRDO for nominating me for two years as external expert on a 100+ crores mission dedicated to developing a specialist recovery tank for the army. 


For obvious reasons of confidentiality, graphs or other results from my project's reports aren't produced here. Read on for a summary of the three projects.

Aiming issue diagnosis, structural optimization and a novel bubbled armor

Project #2 had to do with diagnosing a performance issue of aiming instability in the so- called EX- tank. To this end, I and my team member carried out thorough tests over a ten- day period, using LDV (Laser Doppler Vibrometry) and accelerometers/ microphones to capture operating responses over much of the tank hull and turret, including bogie wheels. The root cause remained a mystery until at the end of the testing period, when we had a breakthrough from new info in one lucky brainstorming session.


Project #3 was to do with design optimization of a sub- performing structural support component of the EX- tank, identified as  cause of the aiming instability. GENSIZ again proved itself well here, yielding a vast number of structurally efficient designs.


Finally, project #4 had to do with development of a novel bubbled- armor, a concept I'd proposed as an alternative to the traditional high- thickness wall commonly used in the tank's construction. GENSOLV, employed in this study, proved itself by producing optimum bubbled shapes vastly superior not only to the flat wall but also to (non- optimal) bubble shapes of hemispherical  form. The study is described in this paper.
