2.”Fixture Design to Improve the Productivity of Mid-Cabin Curtain Production”
The project was jointly undertaken with a local business aircraft finishing company. The project was considered to be a labor and cost saving measure and was aimed at producing mid cabin curtains for a line of aircrafts produced by the company.
3 “Mini Baja Race Car Project” The project involved evaluation of the previous race performance, identifying systems and components on the vehicle that did not perform well enough in the past, perform the necessary technical and stress analysis, redesign and reconstruct these systems and components, and test the vehicle on a simulated race track to evaluate the design improvements.
4. “Design, Construction and Testing of a Four-Point Vehicle Low-Lift System.” A team of three seniors in mechanical engineering technology conceived the need, analyzed the market demand and conceptually designed a system consisting of four electric-powered scissor-type jacks that are remotely controlled from a portable central platform. The project involved the design, development, construction and testing of a prototype.
