Abstract
A 4-seat Wing in Ground effect craft was designed informed by an extensive literature review of past efforts in WIG craft engineering. Several designs were considered during concept evolution. The review identified a reverse delta configuration as best meeting the design requirements. A one-fifth scale of the craft was modelled using blue polystyrene foam and flown using an electric motor in pusher configuration. The flight test verified the design concept, and the effectiveness of the design. A key consideration for effective flight is undercambered airfoils to reduce take-off distance. The model was flyable in sea-state 1. It is estimated the full-size craft can get airborne in sea-state 2. A full-scale model is envisaged.
