Objectives/Goals The objective of this project is to learn about how a hovercraft works, determine the factors that affect performance, and improve design. This project studies a number of forces acting on a homemade hovercraft such as weight, gravity, friction, and lift. Methods/Materials The 4-foot (1.22 m) diameter hovercraft was constructed out of a 3/8 inch (9.5 mm) plywood platform and a skirt made from visqueen plastic sheeting. A leaf blower was used to provide lift and duct tape was used to prevent air to escape at interface of the platform with the skirt and engine. A surface test, skirt test, weight test were performed. The surface test analyzed concrete, artificial turf, and natural grass. The skirt test analyzed a six-foot (1.83 m) and a seven-foot (2.13 m) skirt. The weight test examined three different payloads, 39.91 kg, 28.57 kg and 0 kg. The engine test was conducted using three different engine settings with varying flow rates/air velocities. Re
