EXPERIENCE & PROJECTS

Urban Airspace Technologies, Summer 2012

Intern

Designed a state-of-the-art, remote-controlled floating signage display that is able to float in the air using an aerostat. Performed initial and final calculations and trade studies in order to design, develop and build this product. Using trial-and-error methods to determine and execute the best way to build this product. Used CATIA V5 software to design and render images of the product.

CAD Design & Analysis Projects – CATIA V5

Completed the following CAD design and analysis projects using CATIA V5 software:

• Harley Davidson wheel design

• Motorized can crusher – Design, Motion Analysis and Optimization

• Machine Gun – Design, Motion Analysis, FEA and Optimization

Analysis of Ballistic Impact on Composite Plates

Modeled a projectile and composite plate in HYPERMESH. Used Kevlar 29–epoxy and Kevlar 49–epoxy materials and used 2-d shell elements for modeling. The edges of the plate were fixed. AK-47 bullet was used as the projectile. The steel bullet was modeled with 2-d solid elements and input with a projectile velocity of 700 m/s. The stress/failure analysis was performed on the composite plate at five different ply orientation angles using the ABAQUS solver.

Analysis of Ribs and Spars of an Aircraft Wing

Ribs and spars of a two-seater general aviation aircraft were designed in CATIA and stress analysis was performed in MSC NASTRAN/PATRAN. The shape of the rib was based on an NACA 0012 airfoil. The rib structure was optimized; cut-outs and flanges were optimized based on the stress analysis results. Used an I-beam spar to provide concentration to key loading points due to maximum bending resistance to weight ratio.

Design, Manufacture and Analysis of a Finite Wing

Constructed a finite wing with wood out of an NACA 23018 airfoil with no sweep. Performed wind tunnel tests on the wing at different angles of attack. The results were compared with the CFD results.

Design, Manufacture and Analysis of an Aircraft with Maximum Payload Capabilities

Designed and constructed a model aircraft with maximum payload capabilities using wood. Performed a surface flow visualization in a low speed wind tunnel with a flow speed of 30 m/s. Flow data was measured using pivot tubes that were set up throughout the surface of the model and compared with the CFD results obtained from GAMBIT/FLUENT.

Sonic Boom Mitigation by Aircraft Nose Cone Modification

The sonic boom intensities of five different axisymmetric aircraft nose geometries were studied through analytical method and CFD analysis. The nose geometry was modeled using SOLID WORKS. The CFD analysis was performed using ESI CFD to find geometries of lesser deflection angles producing a relatively lesser sonic boom.

CFD Analysis of Airflow within the Front Wheel Cavity of Automobiles

Performed 2-d and 3-d flow analyses of front wheel cavity of a car using GAMBIT/FLUENT with a rotating boundary condition specified for the wheel. Results indicated drag produced is proportional to the size of the cavity.

Design of an Aerial Firefighting Vehicle

Designed an aerial firefighting vehicle that will replace the fleet of aircraft currently in operation. It is a twin engine amphibious aircraft with a twin tail boom empennage that is designed to carry a payload of 12,500 lbs. This will enable an aircraft to carry 1,200 gallons of water or fire retardant.

CFD Analysis of a Subsonic Joined Wing Aircraft

Modeled a joined wing aircraft in SOLID WORKS. Conducted analysis using ESI CFD in 3 stages: wing tips, wings and interaction between wing and fuselage. The results were obtained to verify increased aerodynamic performance, increased wing structure support, high maneuverability and STOL ability.
