An entry-level vehicle design course, VHCL 260 Vehicle Systems I uses a tunnel-hull design project to introduce students to forces and moments on vehicles and how they affect vehicle design. A tunnel-hull boat is a high-speed marine vessel that utilizes wing-in-ground effect to support a portion of a vehicle’s weight. The tunnel-hull design project introduces students to aerodynamic and hydrodynamic lift and drag. Students alter vehicle-design parameters such as chord length, tunnel span, tunnel-hull beam, and deadrise angles, and perform calculations for lift, drag, and moments on their conceptual models, in order to build scale physical models of their craft. This project, proposed as an alternative to traditional, entry-level engineering projects, seeks to engage students in a design project early in their academic program. It was used in an introductory course as part of an overhaul of the vehicle-design curriculum at Western Washington University. This paper outlines methods for replicating this project in other courses.
