TEAM 1: ON WINGS LIKE A PENGUIN ENGINEERING 339 – SENIOR DESIGN
Project Description • Build an amphibious air cushion vehicle • Should seat two passengers • Two engines: one for thrust, another for lift. • Approximately 12 x 6 ft, triangular shape • Lift engine will duct air into skirt using air splitters
Design Requirements • Approximately 6.5 horsepower lift engine • Approximately 13 horsepower thrust engine • 26 inch diameter lift fan • 48 inch diameter thrust propeller • Hull will be constructed of extruded polystyrene foam and marine plywood • Fiberglass coating on outer hull and ducts • Cable-controlled throttle • Be able to support 400 pound payload
Current Phase • Defining budget (with contingencies) • Sourcing materials • Determining thrust propeller and lift fan specifications • Working on Autodesk model
Lift Fan Design • 26 in. fan diameter • Four blade design • Constructed out of three 1 in. thick pine boards • Blades with varied “angle of attack” for maximum efficiency
Thrust Propeller Design • 48 in. propeller diameter • Two blade design • Constructed out of five 1 in. thick pine boards • Blades with varied “angle of attack” for maximum efficiency • Analyzed to confirm ideal operation
Craft Balance Issues • Center of gravity will be determined using Autodesk Inventor • Components will be placed strategically to balance craft • Weights will be added for static balance if necessary
Duct Construction • Thrust duct will be constructed by cutting polystyrene sheets at a large radius • Duct will then be wrapped and glued into final shape, and sanded • Lift duct will be built into hull, using marine plywood
