Drag
Form Drag

Parasitic Drag

A design that will minimize the impact (Windcut)

Ex. "Sharp/Pointy" nose

Cards forming triangle

Induced Drag

Minamilize

Lightweight Materials, Equipment and Apparatus

Plastic (LIGHTWEIGHT)

Foam core (lightweight)

Skin Friction

Minimalize

Smoother surface

Increase Lift

Buoyancy
Neutral
Positive
Negative
Displacement
Equal to Weight
More than weight
Less than weight

Lift and Thrust System

Delating balloon
Make hole on hull (for the balloon to fit) bigger than the hole underneath the hull (genenrating lift)

A greater SURFACE AREA of the terrain will experience the "wind", so a greater SURFACE AREA of the hovercraft hull will experience the "wind" and help generate lift

The force will be more equally distributed, which will help the hovercraft "float", so generate lift

Plays the same role as the fans
Helped hovercraft glide and create upthrust

Pointed front (triangular)

To help minimize drag

U-Shaped

MAY help minimize drag

To help resist drag, can add something with a sharp edge at the front (ex. two cards forming a triangle)
