Exploring cutting-edge advancements in high-speed impact testing and ballistic research.
This is an ongoing one year consultancy project to carry out the analysis of an Active Protection System (APS) used to counter attack an anti-tank threat, funded by HEMRL.
This is an ongoing one year exploratory project is to carry out the study on Blast Induced Trauma caused by the weak blast loadigng on the head and helmet assmebly. This is funded by ICSR, IITM. The aim is to capture the blast aerodynamics and the structural response of the head-helmet model computationally and experimentally.
This ongoing one year consultancy project is to do the CFD simulations of the flow through improved muzzle brakes and bore evacuator barrels.
This is an ongoing consultancy project from ARDE, Pune, for simulating the projectile motion in an implosion driven launcher. This 1 year project is expected to deliver the design parameters for the implosion driven launcher to be built in ARDE.
This is an ongoing sponsored research project in which I am a co-PI, from DRDO, for the design and the development of a variable camber morphing wing as part of the Center of Propulsion Technology Research Activities, IITM.
This work is to experimentally investigate the short transients and its behavior during the start-up for of an ejector-diffuser system used as a vacuum pump, for various flow and configurations parameters, predict the presence of the recirculation zone and its behavior during the start-up of the vacuum ejector system, predict the nature of oscillations in the secondary and mixing chamber and its damping and estimate the influence of various flow and configuration parameters in the damping of the oscillations.
This is a closed, ISRO funded, In the present project, the flow characterization studies and performance evaluation of an annular aero-spike nozzle equivalent to the an existing engine of ISRO are being carried out. The performance of the engine is being obtained through a as series of cold and hot flow studies at ground level and high altitude conditions with varying back pressure conditions. The performance of the engine are evaluated through the thrust measurements under various nozzle configurations and flow conditions by capturing the pressure data and flow fields using flow visualization methods. The data captured will be used for actual engine development.
This is a closed, 3 year project funded by IC&SR . The objective was to study the unsteady aerodynamics of supersonic projectile in transitional ballistic ragimes. A two stage gas gun is built to accelarte the projectile to supersonic speeds at required Mach numbers. Time resolved schlieren images have been obtained to visualize the transient flow fields and projectile flow-field interactions.
This is a closed, 1 year project. It was funded by Keimyung University. The project obejective was to computationally simulate the launch dyanmics of supersonic projectiles. The influence of viscosity and projectile shapes on the unsteady aerodynamics of the moving projectile in the vicinity of the launch tube was analized. Unsteady drag coefficent of the projectile was estimated for various conditions.
