Abstract

A surfboard fin can be considered similar to a vertical stabilizer in a flow of water. In accordance to production standards in the aerospace industry, these wings are designed, modeled, and tested to specifications of use. Project S.H.R.E.D. implements common performance enhancing designs onto surfboards to allow for better L/D ratios and more favorable coefficients of drag and side force. The designs under consideration are fins with winglets, fins with vortex generators and fins with free hinges. Upon design, these fins are modeled using CATIA, analyzed in CFD using ANSYS Fluent, and then 3D printed for further testing and use. Printed fins are reinforced with fiberglass so as to be comparable to market competitors. Experimental data is collected by means of using a load testing machine to ensure the fin is structurally sound, and by running the fins in a low speed wind tunnel able to match the Reynolds Number they will be subjected to in water use. Finally, the fins are given a qualitative test in the water by project members and local surfers of Daytona Beach. In short,Project S.H.R.E.D. offers students a means by which to apply their academic knowledge to real world situations, in an attractive yet educational way.
