o Various metal finishing techniques were adopted, and stainless-steel parts were powder coated for better durability.

o Experience with maintenance and servicing the machinery and tools at regular intervals to certify them for ensuring optimal performance and efficient productivity. RESEARCH WORK:

• Mold flow simulation of short cut carbon fiber in epoxy resin - [01/15-12/16] o The project aimed at finding the flow front characteristics of the fiber-resin mixture during molding. o Designed several molds in PTC Creo with different aspect ratios. Different nozzle and chamber dimensions were designed and tested to see the variation in the flow front. Similarly, different geometries were also adopted to observe the variations.

o PTC Creo Plastic injection software was used to simulate the flow front of the composite mixture inside the various molds and the flow fronts were observed.

o Flow front was captured and analyzed. It was learned that the flow front varied with varying fiber volume fractions, nozzle dimensions and temperature of the mixture. o Results were recorded and tabulated for future reference. PROJECTS:

• Micromechanics Simulation Challenge – [01/17-05/17] Multiscale modelling of a 0/90 cross ply microstructure characterized by two perpendicular rows of fibers at different fiber volume fractions.

o Successfully designed a simplified RVE which was analytically solved using the Eshelby’s model and calculated the Eshelby’s stiffness matrix.

o A finite element model of the RVE was modelled in COMSOL Multiphysics and SwiftComp at different volume fractions.

• SAE Aero Design – [06/11-05/13]

o Put together and led a team of 8 to conceive and sketch out the initial design on paper. The actual design was modelled in AutoCAD. The wing design was done in XFLR. o Planned and headed the team to set up and acquire wind-tunnel results for the scaled model. o Meticulously fabricated the aircraft entirely of balsa. Carbon fiber spars were used at critical regions. o Helped the team to conduct flight tests and record performance characteristics. o Tweaked the design post flight tests to improve flight performance. o Set up the electronics required for powering the aircraft. Actively learned Radio-controlled flying.

• Design and Performance analysis and evaluation of a UAV with Selig 1223 airfoil wing – [06/12-12/12] o Efficaciously designed and fabricated a wing with Selig 1223 aerofoil for an existing UAV to increase payload carrying capability and improved flight performance. o Various aerofoils were simulated and studied in XFLR. Selig 1223 performed the best. o Carried out wind tunnel test on a scaled model wing with Selig 1223 aerofoil. These results were compared to the data of the former wing.

o Replaced the former wing on the UAV with a full-scale Selig 1223 aerofoil wing fabricated of balsa and conducted tests. As envisioned the changes made on the UAV successfully improved the flight performance.
