Hover crafts have not experienced the popularity of cars, boats or planes, but nevertheless the production of the vehicle is continuously increasing as more and more people discover the recreational, utility, and rescue purposes of the hovercraft. Currently, militaries are the most abundant users of hovercraft, but increasingly people are taking on the hobby of building hovercrafts though kits for their own recreational use (Goldstein). Furthermore, hovercrafts have been built on very large scales and designed to ferry large amounts of cargo. These hovercrafts all use a system of fans that circulate air through the cushion as seen in Figure 1.2. Smaller commercial crafts rely on one fan for transportation, diverting most of the power into inflating the skirt and the lesser amount for movement. The larger crafts rely on two or more fans.
